Will NaBr + H2SO4 (conc.) and shaking ,gassing then the HBr with a device like for gassing compounds with hydrogen chloride work?
Are there any other OTC method to do that?

Well some people told me that NaBr + H2SO4 (conc.) will work but it's unstable, so idk , me it's for brominating parsley oil which contains apiole, to
bromoapiole
Thank you anyways.DJF90 - 30-8-2011 at 05:32
People aren't going to help you if you can't help yourself, especially as you look interested in synthesising compounds that are close intermediates
for questionable compounds. H2SO4 is reduced partially by HBr to yield sulfur dioxide and bromine, but you'd know that if you'd have bothered looking
hard enough.ThatchemistKid - 30-8-2011 at 06:12
Maybe you arnt aware that HBr can hydrolyze ethers, of which your compound has four, depending on the conditions... Let me guess do you plan on doing
a substitution of the Br with a certain amine?
I'm not so sure I have seen EX cooks on here before, a refreshing brand of stupid ...if you are not at all interested in the chemistry...you won't be
spoon fed here.AndersHoveland - 30-8-2011 at 06:32
As DJF90 suggested perhaps hydrobromic acid isn't the best choice if you want to conserve the ether bonds in your product (which I assume you do).
Maybe rearrangement to the propenyl derivative and oxidation to the ketone would be a better idea. Not that I particularly want to encourage you to
make anything illegal, I just hate when people shoot down one idea without offering any alternatives. I'm also not entirely sure my suggestion would
work, but it seems to be well documented with similar compounds.Sergititob - 30-8-2011 at 13:14
Sorry for my bad english it's for making bromoapiole dibromide.
Not for anything illegal guys, so for brominating what i can do with simple methods? and a entire method to make bromoapiole dibromide?
thank you anyways! i'm very interested in chemistry but i didn't have the time to study it in the past.
Any help will be specially appreciated!Nicodem - 30-8-2011 at 13:45

If you want to make "bromoapiole dibromide" then why are you bothering us with questions about how to generate HBr gas? You need bromine (Br2) for
that! At least do some article reading before posting obsolete questions.simba - 30-8-2011 at 13:59
I don't think hydrobromic acid is so harsh on ethers, specially on this situation where not much heat is involved. I've seen people doing the reaction
between sulfuric acid and bromide salt successfully before. Even if some sulfuric acid gets reduced by hydrobromic acid, I think adding an excess of
bromide will minimize this side reaction.Sergititob - 30-8-2011 at 14:20
So adding the br2 to the parsley oil is good? well actually i'm triying to make a psychedelic for personal use only in my country is legal it's
called DMMDA so will adding bromine to parsley oil would yield bromoapiole?
thank you very much infact.UKnowNotWatUDo - 30-8-2011 at 14:32
Adding elemental bromine to apiole will not give you the monobrominated product. DMMDA (or DMMDMA) is what most of us are assuming you are trying to
make. If it is legal in your country, good for you. In any case my previous comment stands. The only way to see if hydrobromic acid would deteriorate
the ether bonds would be to experiment. But if your funds/supplies are limited this might not be an appealing option for you. Which is why I suggested
rearrangement to the propenyl and oxidation to the ketone. If you are making DMMDA you would then perform a reductive amination with ammonia. But this
is all much more difficult than simply adding something to parsley oil and such. If you are already confused by our suggestions (or even the compound
you are trying to make) I would encourage you not to try any of this. Let alone eat whatever happens to be created in your flask by the end!Sergititob - 31-8-2011 at 02:44
Could you or anyone tell me how i can brominate the compound without deterioring it?
Thank you!Retard-3000 - 31-8-2011 at 04:11
No one is going to spoonfeed you here Sergititob, You obviously have a lack of chemistry knowledge so won't be able to pull off the experiment
successfully let alone safely. Sergititob - 31-8-2011 at 07:31
Okay, sorry guys.
Thank you all for the info anyways, congrats for the forum.
See you!chemrox - 31-8-2011 at 10:45
I took a book off my shelf, looked in the index and went to the page. There is a method other than the mixing elements one. I looked on my shelves
and voila; the reagents needed are there should I want to waste precious lab time on something I can order by phone. If you don't know why NaBr and
H2SO4 doesn't work don't mess with it. Organic chemistry is not a blind cookbook sort of activity. It is a science and discipline. You must know
what is likely to happen when you start mixing things. Organic compounds or known to ignite, detonate, run-away in reactions, give off lethal fumes,
etc., etc. Also I think there are cookery forums you can join and ask for spoon feeding but this isn't one of them.Bot0nist - 31-8-2011 at 10:57
I think he has been told enough.
Sergititob ~ Next time, just Google some phrases like bromonation of X, etc, etc. You will find papers and patents and web-pages galore 9 times out of
10. Read these pages and look for anything that could relate to your intended workup. Then, if you don't get much from them post links to them here,
along with a description of what you read and what you don't understand.
You will be greeted in a much warmer and helpful fashion.
EDIT: When I said "bromonation of X" I meant 'X' as a variable, not mdma of course.
