Toxic-gas liberating explosives

madscientist - 20-5-2002 at 20:14

Here are a few ideas for energetic compounds that would liberate toxic gasses when detonated:

(CH2OH)2 + 2HCl --(H2SO4)--> (CH2Cl)2 + 2H2O
(CH2Cl)2 + 2HNO3 --(H2SO4)--> (CHClNO2)2 + 2H2O
(CHClNO2)2 + 2Cl2 --> (CCl2NO2)2 + 2HCl
3(CCl2NO2)2 + 2Na3P --> (CClNO2)6P2 + 6NaCl
(CClNO2)6P2 --> 2CO + CO2 + 3N2 + P2O5 + 3COCl2

CH2Cl2 + HNO3 --(H2SO4)--> CHCl2NO2 + H2O
2CHCl2NO2 --> N2 + CO2 + COCl2 + H2O

CCl3CONH2 + HNO3 --(H2SO4)--> CCl3CONHNO2 + H2O
2CCl3CONHNO2 --> 3COCl2 + CO2 + 2N2 + H2O

(CH2OH)2 + HF --(H2SO4)--> (CH2OH)(CH2F) + H2O
(CH2OH)(CH2F) + 4Cl2 --> (CCl2OH)(CCl2F) + 4HCl
(CCl2OH)(CCl2F) + CH3CH2OH --(H2SO4)--> (CCl2OCH2CH3)(CCl2F) + H2O
(CCl2OCH2CH3)(CCl2F) + NH3 --> (CCl2NH2)(CCl2F) + CH3CH2OH
(CCl2NH2)(CCl2F) + HNO3 --(H2SO4)--> (CCl2NHNO2)(CCl2F) + H2O
(CCl2NHNO2)(CCl2F) --> 2COCl2 + HF + N2

3CH3CHO + 3H2O2 --(H2SO4)--> (CH3CHOO)3 + 3H2O
(CH3CHOO)3 + 12Cl2 --> (CCl3CClOO)3 + 12HCl
(CCl3CClOO)3 --> 6COCl2

CH3CHOHCH2CH3 + HClO4 --> CH3CHClO4CH2CH3 + H2O
CH3CHClO4CH2CH3 + 9Cl2 --> (CCl3)(CCl)(ClO4)(CCl2)(CCl3) + 9HCl
(CCl3)(CCl)(ClO4)(CCl2)(CCl3) --> 4COCl2 + Cl2

(CH2OH)2 + 2HCl --> (CH2Cl)2 + 2H2O
(CH2Cl)2 + HNO3 --(H2SO4)--> (CHNO2Cl)(CH2Cl) + 2H2O
2(CHNO2Cl)(CH2Cl) --> 4CO + 4HCl + H2 + N2

CH3CH2CH2OH + 3Cl2 --> CCl3CH2CH2OH + 3HCl
CCl3CH2CH2OH + HNO3 --(H2SO4)--> CCl3CH2CH2NO3 + H2O
2CCl3CH2CH2NO3 --> 6CO + 6HCl + N2 + H2

CH3COOH + 3F2 --> CF3COOH + 3HF
CF3OOH + CH3CH2OH --(H2SO4)--> CF3COOCH2CH3 + H2O
CF3COOCH2CH3 + HNO3 --(H2SO4)--> CF3COOCH2CH2NO2 + H2O
2CF3COOCH2CH2NO2 --> 8CO + 6HF + N2 + H2

CH3COOH + 3Cl2 --> CCl3COOH + 3HCl
CCl3COOH + CH3CH2OH --(H2SO4)--> CCl3COOCH2CH3 + H2O

Nitrotrichloroacetamide (CCl3CONHNO2) would be a very effective chemical weapon. It is an explosive compound, that, when detonated, would release large quantities of phosgene (COCl2) gas. Approximately 716g of COCl2 would be released when 1000g of CCl3CONHNO2 is detonated. It could be easily prepared by one equipped with a twisted mind. One kilogram of CCl3CONHNO2 would produce enough phosgene to cause ~2148000L of air to have an effectively lethal concentration of phosgene.

Synthesis of CCl3COOH

Acetic acid is reacted with chlorine gas in the presence of ultraviolet light.

Place 60g (58mL) of 100% CH3COOH in a 100mL flask. Set up a "blacklight" (ultraviolet-light emitting lightbulb) directly adjacent to the flask, and turn it on. Keep the temperature of the contents of the flask around 20C. Proceed to gently jet chlorine gas into the flask until the mass of the contents of the flask has reached about 163.5g. Be sure to either use a gas mask, or to be well clear of this reaction; dangerous amounts of HCl gas is produced; and obviously, working with chlorine gas is hazardous.

CH3COOH + 3Cl2 --(UV)--> CCl3COOH + 3HCl

Synthesis of CCl3COOCH2CH3

Trichloroacetic acid (CCl3COOH) is reacted with an excess of ethanol in the presence of concentrated sulfuric acid.

Place 163.5g of CCl3COOH in a 500mL flask. Add 60g CH3CH2OH (76mL) to the beaker. Add 10mL of concentrated sulfuric acid. Allow the contents of the flask to react for several days, keeping the flask stoppered. After the reaction has completed, pour the contents of the flask into an evaporating dish, and allow it to evaporate until all of the water and ethanol has evaporated. Place the CCl3COOCH2CH3 in a 600mL beaker, and carefully rinse it with water for several minutes (this removes the remaining sulfuric acid).

CCl3COOH + CH3CH2OH --(H2SO4)--> CCl3COOCH2CH3 + H2O

Synthesis of CCl3CONH2

Ethyl trichloroacetate (CCl3COOCH2CH3) is reacted with aqueous ammonia at room temperature. The solution is then allowed to evaporate; CCl3CONH2 is the remaining solid.

Place 191.5g of CCl3COOCH2CH3 in a 1000mL beaker. Slowly add ammonia solution until no more CCl3CONH2 is precipitating upon further addition of ammonia solution. Allow the contents of the beaker to evaporate. The resulting solid is CCl3CONH2.

CCl3COOCH2CH3 + NH3 --> CCl3CONH2 + CH3CH2OH

Synthesis of CCl3CONHNO2

Trichloroacetamide is nitrated with mixed acid; the mixed acid is kept cooled in an ice bath. Temperatures are kept below 10C.

Prepare a mixture of 63g HNO3 (42mL) and 98g H2SO4 (55mL) by slowly adding the HNO3 to the H2SO4 (which is in a 1000mL beaker; the beaker is in an ice bath). Keep the temperature of the mixed acid below 10C. Then, *slowly* add 140g of CCl3CONH2 to the mixed acid, keeping the temperature below 10C at all times. Allow nitration to proceed for several hours, monitored at all times. Then, dump the contents of the beaker into a glass fiber filter. Rinse the solid that is filtered with 500mL of very cold water, to remove remaining sulfuric and nitric acid.

CCl3CONH2 + HNO3 --(H2SO4)--> CCl3CONHNO2 + H2O

Detonation of CCl3CONHNO2

Here are a few energetic compositions that would release toxic gasses, and would be very simple to prepare:

5CH2Cl2 + 2NaNO3 --> Na2O + N2 + 5CO + 10HCl

5CH2Cl2 + 4NaNO3 --> 2Na2O + 2N2 + 5H2O + 5COCl2

10CH2Cl2 + 12NaNO3 --> 6Na2O + 6N2 + 20HCl + 10CO2 + 5O2

vulture - 25-5-2002 at 12:38

Sorry to blow your theory and to send all those reactions down the drain, but phosgene is thermodynamically unstable and decomposes above 300C....:(

madscientist - 25-5-2002 at 14:09

Exactly how does it decompose (equation please)? :)

vulture - 26-5-2002 at 05:34

Whaddaya think?
COCl2 -> CO + Cl2 duh......:P

Tsss, all those equations above and you can't figure out this one?

madscientist - 26-5-2002 at 06:56

I have no idea why I asked that question. *smacks forehead* :o

vulture - 8-6-2002 at 12:00

How about a binary of H2 and F2 gas? They still react explosively at -200C :o to form HF, an extremely toxic gas.
Only problem is where to get the fluorine gas.

Madog - 8-6-2002 at 16:17

hehe, even better, an explosive that liberates H2 and F2 so they too explode and then form HF. pretty sick:D

PHILOU Zrealone - 15-8-2002 at 15:54

Sorry Madscientist, but many of the equations you have given are right theorically but practically they are unfeasible or wrong!

5CH2Cl2 + 2NaNO3-->Na2O + N2 + 5CO + 10HCl
5CH2Cl2 + 4NaNO3-->2Na2O + 2N2 + 5H2O + 5COCl2
10CH2Cl2 + 12NaNO3-->6Na2O + 6N2 + 20HCl + 10CO2 + 5O2

Are absolutely wrong! CH2Cl2 boils at 40°C and the volatilisation cools down the reaction very fast; also CH2Cl2 is not very flamable, it only reacts violently with Al ultrafine powder, solid Na or K!
Also:
2HCl + 1/2O2 --> H2O + 1/2Cl2
Na2O + 2HCl --> 2NaCl + H2O
Na2O + CO2 --> Na2CO3
Na2O + Cl2C=O --> 2NaCl + CO2

CCl3-CO-NH-NO2 should be very unstable -maybe so unstable that it doesn't exists; because CCl3 is first a very electroatractive group (thus CCl3-CO- is rather acidic); a good leaving group too, nitramides are much less stable than nitramines; here you have a molecule that should be as (if not more) unstable than dinitrourea.
CCl3-CO-OCH2-CH3 + NH3(dry) -solvant-> CCl3-CO-NH2 + CH3-CH2-OH
But
CCl3-CO-OCH2-CH3 + NH4OH --> CCl3-CO2NH4 + CH3-CH2OH

Finally:
(CH2OH)2 + 2HCl --(H2SO4)--> (CH2Cl)2 + 2H2O
You forgot:
+(CH2O)2SO2 + (CH2)2O + HO-CH2-CH2-Cl

(CH2Cl)2 + 2HNO3 --(H2SO4)-->(CHClNO2)2 + 2H2O
Unfortunately no; aliphatic nitrocompounds aren't made the same way as alcenic/benzenic nitrocompounds!


(CHClNO2)2 + 2Cl2 -->(CCl2NO2)2 + 2HCl
The first one is already very dangerous and unstable see related compounds like CH2Cl-NO2 and CHCl2-NO2!

3(CCl2NO2)2 + 2Na3P --> (CClNO2)6P2 + 6NaCl
Why not, possible, no fuking ID!

(CClNO2)6P2 --> 2CO + CO2 + 3N2 + P2O5 + 3COCl2
Might be P2O3, N2, CO2, CO and Cl2!

CH2Cl2 + HNO3 --(H2SO4)--> CHCl2NO2 + H2O
Maybe at under pressure boiling at reflux (with very big risks of explosion (CH2Cl-NO2 and CHCl2-NO2).

2CHCl2NO2 --> N2 + CO2 + COCl2 + H2O
Nothing new under the sun; it is known for ages that halonitrocarbons like Trinitrotrichlorobenzene, chloropicrine (CCl3-NO2-toxic on its own), haloalkanes mixed with oxydisers like peroxydes, NH4NO3, N2O4, O3, liq O2; H2O2, HNO3 conc, HClO4 conc, ... do produce some free halide, CO and traces of X2C=O + H2O and HX!

CH3CH2OH + 3Cl2 --> CCl3CH2OH + 3HCl
I'm almost sure that will never go this way, but more this way:
CH3-CH2OH + Cl2 --> CH3-CH=O + 2HCl
CH3-CH=O + Cl2 --> CH2Cl-CH=O + HCl
CH3-CH=O <--> CH2=CH-OH
CH2=CH-OH + Cl2 --> CH2Cl-CHClOH
CH2Cl-CHClOH --> CHCl=CHCl + H2O
CH2Cl-CHClOH --> CHCl=CHOH <--> CH2Cl-CH=O
...--> CHCl2-CHCl2 and CCl3-CH=O (chloral)
The action of NaOCl (Javel water) on ethanol provides partially chloral hydrate.

CCl3CH2OH + HNO3 --(H2SO4)--> CCl3CH2NO3 + H2O
CCl3-CH2O- must be quite acidic and thus the ester will not be stable, maybe doesn't exist!

CCl3CH2NO3 --> 3COCl2 + CO + 2H2O + N2

CH3COOH + 3Cl2 --> CCl3COOH + 3HCl
This one is true :o

(CH2OH)2 + HF --(H2SO4)--> (CH2OH)(CH2F) + H2O
And also (CH2F)2!

(CH2OH)(CH2F) + 4Cl2 --> (CCl2OH)(CCl2F) +4HCl
See the reaction of ethanol with Cl2 and extrapolate to this twin brother!

(CCl2OH)(CCl2F) + CH3CH2OH --(H2SO4)--> (CCl2OCH2CH3)(CCl2F) + H2O
Why not!
(CCl2OCH2CH3)(CCl2F) + NH3 --> (CCl2NH2)(CCl2F) + CH3CH2OH
Maybe, maybe not; possible reaction of the halide with the amine...cf CH3-NH2 with CH3-Cl
--> CH3-NH2Cl-CH3 --> (CH3)3NHCl --> (CH3)4NCl

(CCl2NH2)(CCl2F) + HNO3 --(H2SO4)--> (CCl2NHNO2)(CCl2F) + H2O
Primary amine doesn't form nitramines in presence of H2SO4...do you do RDX with H2SO4/HNO3 or with HNO3 conc with other dehydratants than H2SO4? True that H2SO4 is used in NITRAMIDES synthesis not in nitraMINes!
(CCl2NHNO2)(CCl2F) --> 2COCl2 + HF + N2

3CH3CHO + 3H2O2 --(H2SO4)--> (CH3CHOO)3 + 3H2O
I like the idea, but nowhere I have seen any mention of acetaldehyde peroxyde; nor of formol peroxyde!This must mean they are so unstable they decompose immediately at ambiant T or while forming!

(CH3CHOO)3 + 12Cl2 --> (CCl3CClOO)3 + 12HCl
It would be more like: --> HCCl3 + H2O + HCl + CO2 + CCl3-CH=O + CH3-CO2H + CCl3-CO2H

(CCl3CClOO)3 --> 6COCl2
Noway; but CH3-CO-CH3 --> ClCH2-CO-CH3 and ClCH2-CO-CH2Cl that may form a CTAP brother halogenated that will free traces of phosgene
Those halogenated CTAP will have higher densities, better oxygen balance (since Cl2 is an oxydiser) and thus display higher VODs!
Haloacetons are very reactive compounds they can polymerise explosively on their own, they are strong lacrymator and must be suffocating gases like any halogen reactive containing compound (Cl-CN, Cl2, Cl2C=O, Cl2O, ClO2, Cl2S, TiCl4, AlCl3, NCl3, ....).

CH3CHOHCH2CH3 + HClO4 --> CH3CHClO4CH2CH3 + H2O
True but perchloric ester are spontaneously detonating compounds at ambiant T!

CH3CHClO4CH2CH3 + 9Cl2 --> (CCl3)(CCl)(ClO4)(CCl2)(CCl3) + 9HCl
Detonation will occure before the molecule has any chance to react that far!
(CCl3)(CCl)(ClO4)(CCl2)(CCl3) --> 4COCl2 + Cl2
No comments!

(CH2OH)2 + 2HCl --> (CH2Cl)2 + 2H2O
True!

(CH2Cl)2 + HNO3 --(H2SO4)--> (CHNO2Cl)(CH2Cl) + 2H2O
Only under vapour phase at high T (400°C) no need of H2SO4!

PHILOU Zrealone - 15-8-2002 at 16:07

2(CHNO2Cl)(CH2Cl) --> 4CO + 4HCl + H2 + N2
Yep!

CH3CH2CH2OH + 3Cl2 --> CCl3CH2CH2OH + 3HCl
Not accesible that way!

CCl3CH2CH2OH + HNO3 --(H2SO4)--> CCl3CH2CH2NO3 + H2O
Interesting high density, for sure!

2CCl3CH2CH2NO3 --> 6CO + 6HCl + N2 + H2
Yep!

CH3COOH + 3F2 --> CF3COOH + 3HF
F2 often explodes upon contact with organics!
CF4 + CO2 + HF are the results!

CF3COOH + CH3CH2OH --(H2SO4)--> CF3COOCH2CH3 + H2O
Yep!

CF3COOCH2CH3 + HNO3 --(H2SO4)--> CF3COOCH2CH2NO2 + H2O
Nope esters doesn't survive acids!And alkyl nitrocompounds does only form at high T (350-450°C)!
You will more likely form CH3-CH2-ONO2 and CH3-CH2-SO4H with serious risks of explosion owing to the very strong acidic trifluoroacetic acid!

2CF3COOCH2CH2NO2 --> 8CO + 6HF + N2 + H2
Yep, but made via nitroethanol (formol/nitromethane 1/1-10).

CCl3COOCH2CH3 + HNO3 --(H2SO4)--> CCl3COOCH2CH2NO2 + H2O
Same as above!

2CCl3COOCH2CH2NO2 --> 8CO + 6HCl + N2 + H2
Yep!

Doesn't

NH4N3 liberate toxic gases. This might be wrong, I'm a bit tired at the moment but I recall reading about it at E&W forum. However it's currently down.

vulture - 17-11-2002 at 15:16

Nope, just N2 and H2....

If it wouldn't produce N2, it wouldn't be explosive at all, because the triple bond formation releases so much energy.

madscientist - 17-11-2002 at 17:17

Wouldn't ammonia be one of the products of the detonation of ammonium azide? Ammonia has an exothermic heat of formation, if I remember correctly, which would mean that it wouldn't break down into its elements.

I think it`s possible making high nitrated explosives, when bounding phosphorus with other chemicals, for instance
tri(2,3,4,5-tetranitro-1-tetramethyleneiminyl)phosphine.
[TTTIPP]

This explosive must be protected from
agressive chemicals or it will decompose !!!

I post the chemical structure later.

Krypton - 18-2-2003 at 21:45

Here the chemical structure of the pyrrolidine-based component.

Does anybody have ideas for a easy synthesis-way to make this explosive ?

ok, I'm not too good (I actually suck) with these chemical equation things but NI3 does give out iodine gas and iodine is poiosonous

Haggis - 22-2-2003 at 22:45

Yes, Iodine vapor wouldn't be good for you, but the purpose of having an explosive that liberates toxic gas is to actually be able to use the explosive. NI3 would just be too sensitive to have any practicality other than entertaining chemistry students. Wouldn't the equation go like this?
2NI3--->3I2+N2 Wouldn't every 1069.4 grams of NI3 decompose to 761.4 grams of I2? No person is insane enough to deal with a kilogram of NI3, the amount of I2 produced at 5 grams is quite high, 3.56 grams. Although it gives off a lot of I2 per gram of NI3, the explosive part of it is the problem.

DeusExMachina - 23-2-2003 at 10:08

how did Mega set it off? He has some pictures and I tihnk a video of him setting off large pile of it with a feather... isn't that kinda dangerous? someone can set it off like he did

Krypton,
Do you have any reference for the building bloc of your idea?
cyclo(-NH-CHNO2-CHNO2-CHNO2-CHNO2-)
Should be hell of a good explosive on its own...especially the nitramine... perfect OB :D
O2N-N(CHNO2-CHNO2)2 --> 4CO2 + 2H2O + 5/2N2

High density but must be sensitive!

Holy shit, that would be a lethal radius of 12.9 m or over 42 ft. If you wer considering a hemisphere instead of a sphere, that would be a radius of 16.3 m or over 53 ft. :o

I sincerely hope all of this is hypothetical. :o

PHILOU Zrealone - 10-4-2003 at 03:53

716g of Cl2C=O is 7,24 moles
A 100% cloud of phosgene would fill a volume at STP of 162,24 liters but here we are in a detonation process where the heat is much higher (let say 1500°C); volume reaches 1160 liters then under atmospheric pressure.

Of course 100% phosgen is lethal but 1% is lethal too; it is only a mather of time exposure!If toxicity range is known you may know the limit range of lethal action!
From the datas of madscientist: it seems
toxicity is at 0,0075% by volume!

Theoretic - 1-7-2003 at 07:26

"Nitrogen trichloride, also called nitrogen chloride, agene, chlorine nitride, trichloramine, trichlorine nitride, chloride of azode, or Stickstofftrichlorid, is an unstable primary explosive compound. Its preparation is not complicated and the chemicals used are simple, cheap, and readily obtainable. You could pump the stuff out by the liter if it was not so sensitive. Nitrogen trichloride will explode if heated, exposed to sunlight, or mixed with organic compounds. It does not like to be friendly around many other chemicals, shock, sparks, and it will explode if frozen and thawed. The explosive properties were first reported in the 18th century by Sir H. Davy, he had this to say: "The fulminating oil which you mentioned roused my curiosity and nearly deprived me of an eye. After some months of confinement I am again well." Ouch, that must have hurt."

Sounds interesting?
Nitrogen trichloride decomposes like this: 2NCl3->N2 + 3Cl2.
That's how it's made:

"Dissolve 30 g of ammonium nitrate in 70 mL water in a 200-mL Erlenmeyer flask. Prepare a chlorine generator as described in the synthesis section. Place a tube connected to the generator at the bottom of the flask so the chlorine gas can bubble into the liquid, a bubbler will help a lot with the reaction. Gently heat the flask to start the reaction while adding chlorine gas. An oily yellow liquid will begin to appear on the bottom of the flask, that is the nitrogen trichloride. Stop heating the flask when the drops appear. After 20 to 30 minutes the reaction should be complete. Use a medicine dropper to extract the nitrogen trichloride from the flask, transfer it to a small test tube and remove any water accidently sucked up with it. You will need a graduated cylinder for measuring liquids. This explosive will decompose within 24 hours of its preparation.":cool:

On page 140 of "Davis" there is mention of Dinitrochlorobenzene
producing Phosgene.

The normal products of any explosive are not sweet in general and
considered toxic as a rule. Any substance producing products that
are banned by international treaty would itself be banned, and only
of interest to terrorists. Disseminating toxic clouds is best done
by aerosolizing with an explosive charge. This is how chemical
weapons have always been constructed.

For a nasty downwind vapor hazard how about Hydrogen Sulfide
solvated in perchloric acid. SH3ClO4 -> HCl + SO3 + H2O

Or if area denial is your scheme try an explosive salt of a
radio isotope, the kind used in nuclear medicine.

Jome - 5-6-2006 at 02:01

Not explosive in it self, but teflon powder (or teflon in any form) added to an explosive would likely release toxic gas like COF2, PFIB and other nasties due to the thermal decomposition of the material.

Also CuF2 is likely to release the dreaded F2 if heated, just like CuCl2 releases Cl2. Adding these to an explosive would likely lead to "at least" the formation of HF, perhaps if OB was negative the free F would react post-boom with CO to give COF2.

How about dinitro/trinitrofluorobenzene mixed with potassium chlorate? The former could be made by Anilline + nitrous acid at low temps + some fluorinating agent like AlF3, followed by nitration into di-nitro. Dont know how hard that first step would be though, halogens in rings are de-activating after all.
The compound, or at least the mono-nitro fluorobenzene (mix with O+ comp like AN?) is likely to be very toxic by itself.

I (and my former 2000mL flask) beg to differ.

It makes sense to make a LOT at once (enough to last you, well, basically forever), and when purified, washed etc, keeps fairly well sealed under distilled water.

It still isn't useful at all though, I agree, except for putting in keyholes and such.

quicksilver - 6-6-2006 at 07:06

While somewhat differing from a topic of "toxic" there is a marvelous method to release clouds of Oleoresin Capsicum ("pepper spray" CAS# 8023-77-6). This may be obtained for pennies or in USP form for quite a bit more but the product is basically the same. It is contained in a "mirco-prill" which is not distrubed by a "cool" high explosive like nitroguanidine. So long as the initiating explosive does not scorch - the prill is air-bourne. Thus there are the standard shells & gas granades which "push" the OC material but there are also those made by Defense Technology Corp of America which utilize a triple base smokeless powder that is very high in niroguanidine (it's actually mostly Nitroguanidine) with a small det (like a #4). The material is launched into the air in clouds of fine particulate matter as a direct mix with the HE. These are called "Non-continuous Discharge Genade 107 or T-16 Flameless Expulsion Genade" - Same company.
I believe the patent is US5069134 but that may be for a CO2 version (I have the material on another computer).
The "mini-prill" may be made by simply evaporating any of the numorous products on the market which use OC in a carrier of alcohol. The OC material in a carrier of ethylene glycol is already in mini (micro) prill form - just look under a microscope. In bulk OC may be obtained for about $80 a pound but considering that a grenade dose is less than a gram and that will fill a 30' x 30' room....it goes a LONG way!

Mg3N2 + 2 CHF3 => 3MgF2 + 2 HCN

How much actual HCN is made given the temperature evolved is an open question.
Nice thing about this though is that venting the Freon from confinement leaves
the Mg3N2 component inert.

Cyanuric triazide exlodes with formation of cyanogen, formaldoxime is also explosive if fast heated and generates lots of HCN. As it comes to halogenated hydrocarbons flourine based ones are generaly far more toxic, one example is flouroacetates witch can be produced from it's methyl ester witch can be prepared by fusing methylchloroacetate with NaF in autoclave, however stuff is too nasty for somebody to try this. Also one should remember that many compounds as common chemical warfare agents are decomposed in blast wave, however some are able to be volatized in such manner, examples are lacrymators such as CN and nerve agents like sarin.
