Unusual Chemicals, what to do with them ...?
Hi, I have a few questions ... I think everybody faced with this problem. When you have some chemicals ...but you dont know what to do with them  I have a few reagents(from old lab...) with what I don't know what to do and they are
quite expensive nowadays... I have about 2kg of Nitrosomorpholine C4H8N2O2
at http://www.sciencelab.com/page/S/PVAR/SLN1576 here it cost A LOT OF .... 60$ for 1g... Why it's SO expensive...?
Second ... Also few kgs of PHENYLANTHRANILIC ACID. Maybe some suggestions and/or some syntheses involving those materials ? I couldn't find any
syntheses with those reagents. So please, help me Thank you.
EbC: Made title slightly broader, to welcome input not just on expensive chems...

Just save them until you find a use for them. Where did you get those anyway?

I haven't checked nitrosomorpholine but I know a lot of the nitrosamines are carcinogenic. That makes them more difficult to handle and might explain
the high price.

I have another odd one, benztriazole.
(without the extra R1,2,3 phenyl).
What can you do with it? I know it is used in photography, it looks pretty reducing, but I don't know what it can be used for...

I know theres an explosive which uses it in the synthesis; BTX.

Easy if you can make picryl chloride.

I've got 100 ml of Chlorotrimethylsilane that I have yet to find a use for. I used about 2 ml to make some nitrotrimethylsilane for some odd reason
but have yet to find use for the rest. Any resonable suggestions?

I have about 300 lbs of Guanidine hydrochloride I have been trying to find a good use for.
Anyone comes up with a good idea for a useful synth... I'll send you some of it.
Maybe an aminoguanidine something...

BromicAcid 
You can do much with it, a good start would be to enolize acetone ( http://www.orgsyn.org/orgsyn/orgsyn/prepContent.asp?prep=cv8... and simillar http://www.orgsyn.org/orgsyn/orgsyn/prepContent.asp?prep=cv7... ) and try to do an arylation of it with a aryl halide or a diazonium salt (copper
catalysed), I haven't seen this in litterature, but chances are big that you can make phenyl-2-propanones, but beware, plain P2P is illegal to posses.

lbs!!?? Is that a typo? If it is not I would definatly like to hear how you came into that!
I know it is a precursor to tetrazoles
Me, I've got some neodymium and antimony that I don't really have a use for. No ideas whatsoever for the neodymium, but the antimony I plan to make
some chlorides of when I have a place to do it...

It's no typo.
Originally acquired for the synthesis of 3,6-dihydrazino-s-tetrazine but that chemical is no longer of interest, so the GHCl collects dust.

Sweet jesus! What country are you in, I would pay you for some of that! I'd use it to make aminotetrazole and nitrotetrazole, and also a very
interesting high impulse rocket propellant of some complex structure which is the salt of triaminoguanidine. Despite having so little oxygen it has
solid carbon in the exhaust, it has a Isp of 230 or thereabouts. I remember the synth looked doable but needed a fair amount of hydrazine for the
triaminoguanidine, but nothing too exotic.
I just tried a synth of guanidine nitrate (urea + AN) a few days ago, and I would like to get that working, but I wouldn't say no to a pound or two of
the chloride salt.

Uses of neodymium include:
1) Neodymium is a component of didymium used for colouring glass to make welder's goggles.
2) Neodymium colours glass in delicate shades ranging from pure violet through wine-red and warm gray. Light transmitted through such glass shows
unusually sharp absorption bands; the glass is used in astronomical work to produce sharp bands by which spectral lines may be calibrated. Neodymium
is also used to remove the green colour caused by iron contaminants from glass.
3) Neodymium salts are used as a colourant for enamels.
4) Neodymium is used in very powerful permanent magnets - Nd2Fe14B. These magnets are more expensive, but lighter and stronger than samarium-cobalt
magnets. Neodymium magnets appear in high-quality products such as microphones, professional loudspeakers, in-ear headphones and computer hard disks
where low weight, reduced size or powerful magnet are required.
5) Certain transparent materials with a small concentration of neodymium ions can be used in lasers as gain media for infrared wavelengths (1054-1064
nm), e.g. Nd:YAG (yttrium aluminium garnet), Nd:YLF (yttrium lithium fluoride), Nd:YVO4 (yttrium orthvanadate), and Nd:glass.
6) Probably because of similarities to Ca2+, Nd3+ has been reported to promote plant growth. Rare earth element compounds are frequently used in China
as fertilizer.

Thank you for that pdf ,but I am not interested into explosives. Nice thread.... Anyone can ask what to do with that or another reagent ...  Maybe some more ref's on that compounds ?

I also want to mention a few special chemical, which I have. I could not resist buying them, when I could obtain them for just EUR 7,- per liter,
reagent grade quality:
2-methyl 1-propanol: CH3CH(CH3)CH2OH
4-methyl 2-pentanone: CH3COCH2CH(CH3)CH3
triethylamine: N(CH2CH3)3
Besides that, I also have 50 ml of N-(2-hydroxyethyl) piperazine.
If anyone out there knows interesting synths or experiments with these chemicals, then I would be very pleased. At the moment they are stored in their
original bottles, unopened, collecting dust.

I am sort of in the same boat. A while back I bought a liter ofr Triethanolamine N(CH2CH2OH)3. I think the only thing I found via search engine was
mustard gas/war gas(search was done a year ago). Hopefully someone might be able to suggest something a little tamer

Triethylamine is very useful for preparing esters of phosphoric acid from the chlorides and an alcohol. It precipitates out of solution as the
hydrochloride salt, is filtered off, and the products distilled to remove any unwanted esters (mono or di or whatever).

Triethyl perhaps, but triethanol?
Sounds kinda sticky, in an polar way.. a flower of electronegative elements huh?

I think triethylamine can be used in Demethylation of Vanillin it yields protocatechualdehyde. Here is quote from rhodium.
| Quote: | From Rhodium
Vanillin Demethylation with Pyridine and AlCl31
Anhydrous AlCl3 (9.7 g, 0.0724 mol) was suspended in a solution of 10g (0.0658 mol) of vanillin in 100 ml of methylene chloride in an apparatus
protected from atmospheric moisture. While stirring briskly and cooling to maintain the temperature at 30-35°C, 22.9g (0.290 mol) of pyridine was
added slowly. The reaction was vigorous; the resulting clear light orange solution of the reaction complex was heated to reflux (45°C) and maintained
at that temperature with stirring for 24 hours. The solution, which had darkened only slightly during the reflux period, was cooled to 25°C and the
product was hydrolyzed, while stirring and maintaining the temperature at 25-30°C, by the addition of dilute (15-20%) HCl until the mixture was
definitely acidic to congo red indicator. Of the two phases present at this time, the lower methylene chloride layer contained most of the small
amount of the unchanged vanillin, and essentially no protocatechuic acid, the latter was dissolved in the aqueous phase. Evaporation of the methylene
chloride yielded 0.8 g of vanillin. Extraction of the aqueous phase with ether followed by evaporation of the ether left 7.9 g (87%) of pale yellow
crystals of protocatechualdehyde melting at 153-154°C.
Using the cheaper triethylamine in place of pyridine lowered the yield to 61.5%

The latest addition to my collection of impossible to get chems.
Old #72
mw- 178.49
99.89%
Now....what to do with it ?
The nitrate salt sounds interesting

Another one for me: D2O(100ml bottle, 2/3-3/4 full)...Might give that cold fusion experiment a try if I can find that site which gave specifics...
Unless anyone else has suggestions.

D2O- you could prove its identity by growing bacteria in them, or rather, an agar-based medium thereof.... in D2O organisms grow slower, or not at
all. Also, if you are after some metabolite, you could make deuterated versions of it.... which are of great utility in NMR (I.e. glucose, ATP,
whatever). Not quite realistical on such a small scale though.
Ordenblitz... I don't get it... what IS it you are having? Old #72???
Ah got it... Hafnium metal... what on earth could you want with it? You could play a bit of inorg. chem... the lanthanides ... always fun, since they
aren't that well characterised.

I bought an ancient tin of lead arsenate at a flea market. The tin is really cool looking, which is the main reason I bought it. Its also cool to
freak people out when you show them it what with the whole double whammy lead and arsenic mojo. But what the hell to do with it? Damned if I know.

Flow fluorine over it, distill off the AsF5 and dissolve in HSO4F.

bennzatriozole is also known as Kodak AntiFog #1. It takes the light sensitivity down a notch or two. IfIRemember correctly. It helps reduce fog in
both papers and films.
