A source for t-butanol
Hello everyone, I have been excitedly reading through the potassium thread and have all the stuff needed to do a few trials of my own except
T-butanol, I have looked many places and aside from making it from methyl magnesium bromide and acetone I cannot find a source for the home chemist.
There are a couple of over the counter cleaners that have T-butanol in them, one of which I found in a computer store for 20 dollars a bottle, seems
to not be worth the price with all the other crap that was in there.
So could someone help direct me to source of T-butanol?
Thank you

You're welcome, hk. I wasn't aware of this fine source either until it was mentioned in passing by Evil Lurker several years ago.
I have been somewhat protective of these good sources, afraid that they would be abused. But my thinking now is that we should give them as much
business as we can. Poor economics is probably more of a threat than the 3-letter agencies.

Bump w/reluctance...mom or rather her attorneys is (eventually) a bigger threat...when they say, well, fuck this.
When I first saw this thread, I thought, oh someone posting something. Oh, a source request thread in disguise, great, and it worked. Bitch bitch
bitch
bitch bitch bitch
ok
that was predictable. Carry on. IMHO liability potential from "us" exceeds profit potential for most of this sort who will deal with individuals.

some brands of glowsticks contain tert-butanol I don't know what percentages though,where I'm from t-butanol is unobtainable,though I managed scavenge
some.

t-amyl alcohol
does anyone know where you can get t-amyl alcohol. Post Apple Scientific doesn't carry it.
I know this thread is on t-butanol... but I'm guess that those who want this teriary alcohol is doing it to make potassium. I want to try it with
t-amyl alcohol, but I can't find any source for it.

Do you have evidence of this, or is it, as you say, IMHO?

Pardon my asking but where did this come from and who/what are you
referencing? How can an alcohol cause anything near this much trouble? Its used in bloody Glowsticks for crying out loud. call me what you will but
still: I don't see the fuss.

The issue is whether or not to publicly reveal valuable sources (chemical suppliers who will sell to individuals). This is an issue which gets
debated periodically on this forum. Perhaps it is time for this important subject to get another good airing.

It's hard to believe but it was an off-topic reply; couldn't resist trolling, that's all. No doubt, all K made by us will be made not-K uneventfully;
no worries about the butanol then. Companies that send some degree of unusual and/or reactive items to residences may face the relevant
degree of possible legal entanglement these days. I wouldn't have posted if PAS was a soap making supplier.
If some criminal case involving some agency happened, one phone call or letter would put the company on notice - which is a thing, especially from the
DEA. Maybe they would restrict only parts of their catalog in such a case. Or not.

I found it once on a site that dealt in research chemicals. It was listed as "2m2b" or 2-methyl-2-butanol rather than "tert-amyl". Apparently some
people drink a few mL of it to mimic ethanol intoxication...
I think the site was called "purechems" or "puritychems" or something similar to that. I think it might have been a .uk site because their items were
listed in pounds. I also somewhat recall that they wouldn't sell to me for some reason... Maybe they couldn't ship it to me

As incredibly nerdy as this sounds, I actually got some t-butanol simply because of its interesting properties (such as, it freezes near room
temperature). That, and the fact that tertiary alcohols are just really neat - chemical properties and everything. There are some interesting
qualitative / test reactions that can be done with it IIRC.

That's the reason I bought some also.

I have already given a source upthread. Why do you want to know where I bought it?

Very sorry, I missed that. I wanted to know where you acquired it to get a feel of the sort of places in the UK that might a) have and b) sell it to
me.

| Quote: Originally posted by Nicodem | The general SN1 substitutions of MTBE go like this (where HNu is the nucleophile):
tBu-O-Me + HNu ---(acid catalysis)---> tBuNu + MeOH
In the case of HNu = HCl:
tBu-O-Me + HCl -----> tBuCl + MeOH
Since methanol is a primary alcohol, it can not undergo SN1 reactions, though it can react under the same conditions in other ways, depending on the
conditions and nature of the nucleophile and catalyst (e.g., if HNu is CH3COOH, then it can obviously get esterified, while if HNu is HI it can
undergo SN2 substitution to yield methyl iodide, etc.).
...
PS: In context of another thread an advice for those that have no distillation apparatus: N-(t-butyl)acetamide is a solid at room temperature (mp
96-98°C). So, if you wander what else you can do with MTBE, do this using the Ritter reaction on acetonitrile. If you have no acetonitrile, you can
use urea as the nucleophile (the patent number for Ritter reactions using urea is already posted in some other thread). |
I was looking for some posts at SyntheticPages and found the contribution "Esterification and Ritter reaction in one pot of cyanoacetic acid;
N-tert butyl malonic acid methyl ester" by R. Ramakrishna (DOI: 10.1039/SP532). I remembered this post where I suggested the use of MTBE for Ritter reactions and ironically in the same post I also
speculate that carboxylic acids would be esterified to their methyl esters under such SN1 conditions. Nice to see how someone actually applied this
property in a preparative reaction, and with excellent yields as well. Looks like an interesting option for the average amateur application of MTBE.
…there is a human touch of the cultist “believer” in every theorist that he must struggle against as being
unworthy of the scientist. Some of the greatest men of science have publicly repudiated a theory which earlier they hotly defended. In this lies their
scientific temper, not in the scientific defense of the theory. - Weston La Barre (Ghost Dance, 1972)

Isobutane is found in some camp stove fuel mixtures.
Radical bromination of isobutane results in a 100% yield of tert-bromo-isobutane. Radical chlorination results in yields nearly as high.
And that is the interesting thing, because apparently radical halogenation can be very selective:
source: http://www.grossmont.edu/martinlarter/Chemistry%20231/Reference/Alkenes7_oxidation_given_Lecture21[1].pdf
"For a chlorine atom, abstraction of a tertiary hydrogen is favored over abstraction of
a primary hydrogen by a factor of about 5 on a per hydrogen basis."
Then just react this with aqueous base to get tert-butyl alcohol. (converting a chlorine group is more difficult, requiring hours of reflux with NaOH,
or a CuI catalyst, but still takes 1 hour reflux)
