Ontario... I asked the guy at Canadian Tire and found some in the back. Apparently they don't put it on the shelf anymore. I did, however, buy a litre
of it off the shelf at a Home Depot

not really chemical, but lab related.
I got the PDF online and then got it printed and bound for a mere 36EUR. now I don't need to fool around with those irritating PDF's

just stopped by the pharmacy to get some diethyl ether.
19.80 EUR for 1l.
It is however not dry, so you need to either put Na in it or redistill it.
they will also sell CHCl3 OTC, but it's 80EUR/l or 30EUR for 250ml

I had an OTC frenzy.
5l acetone
5l MeOH
5l 23% HCl (For cleaning)
5l of NaOCl to titrate (2,5%) to make CHCl3 (0.90eur/5l. I am going to need about 150l to get a bit over a liter of CHCl3 for 45 eur!)
and from the gouden pluim:
1Kg anh. AlCl3
1Kg urea
100g Na2S2O3
2l 37% HCl

I got my Al powder for free from skylighter, they had a deal where if you spent $60 they would give you 5lbs Al free! Money well spent.

From a Polish eBay seller:
- ethanol amine: NH2CH2CH2OH, a colorless liquid, somewhat more viscous, like water
- diethanol amine: NH(CH2CH2OH)2, a colorless liquid, a little more viscous than conc. H2SO4
- triethanol amine: N(CH2CH2OH)3, a colorless liquid, extremely viscous, like a syrup.
- propionyl chloride
- dimethylformamide
The ethanol amines I want to use in ester-experiments with nitrous acid and maybe some other acids as well. The propionyl chloride I purchased,
because I could. It most likely is a one-time occasion, which I could not let go by.
The dimethylformamide is said to be useful in making dimethylamine. I tried that already with NaOH and water, but the reaction is not as smooth as I
hoped. Maybe someone else can comment on that.

Dang, Calcium Chloride Anhydrous is rather expensive, ~$25.23 for 100 grams=$250 for 1Kg

I got mine for about $15 as a dehumidifier refill.
Consultation with the MSDS says that it's practically pure Calcium Chloride.

$15 for 1Kg, that's a great price.... I guess it's a lot more expensive for the 'lab grade stuff'.

I indeed buy anhydrous CaCl2 by the kilo in a hardware store, for just a few euros per kilo. It is good enough for drying purposes and for basic
experiments with calcium salts. Solutions of it are somewhat opalescent, but if I want to experiment with that, I dissolve some in water and set it
aside. The next day, there is a perfectly clear colorless solution above a thin layer of pale brown solid matter. With a syringe I carefully suck away
the clear liquid and the last 10% or so I discard (this can be done, because it is so cheap).

I was recently given around 500g or resorcinol and a bottle of "potassium bromide salt". This was from another home chemist who was getting rid of
their stuff. I thought the "potassium bromide salt" was KBr but it most obviously isn't. Upon adding some ~50% H2SO4 there is an
immediate production of bromine fumes and after a few minutes there is a large blob of elemental bromine accumulated under the undissolved salt. What
could this stuff be? BCDMH?
This person has severe chemical labeling issues apparently.

Maybe potassium bromate? or bromate and bromide salt mix?
I'm not too good at putting label too, I would have to be there if someone was to get my chem, else then that, about 15% would be unlabeled. I
generally put label in the summer, and in the winter I write the molecualr formula on the bottle.
I never asked for this.

I would guess they reacted bromine with potassium hydroxide, producing a mixture of bromide and bromate. Acidification of this mixture will produce
bromine.

That could be, but the amount is ridiculous, something like 3 kilos... ThTs a lot of bromine to waste- or dispose of I guess. Also, it is not of
"salt" consistency like the reagent grade KBr I have, it is a very fine powder clumped together reminiscent of corn starch but denser.

Sulphuric acid can oxidize bromide to bromine. http://www.youtube.com/watch?v=QkTu7yKSyzg

I shall take photos later to demonstrate the difference. When a spatula of KBr is added to one test tube and a spatula of this unknown material is
added to another, 4ml water added to each and then 4-5 drops concentrated sulfuric acid added to each there is a clear difference. The liquid in the
KBr tube becomes orange, and that's about it. The other tube however becomes orange and then quickly the air in the tube becomes orange with Br vapor
and eventually a drop of Br forms.
I read about BCDMH and it states that it has a slightly acetone odor, this stuff does. I think it may be that...
