Could the bromosafrole? be tested by dropping it into cold H2SO4, and hoping it don't dissolve, or is there some other reliable method. Btw, it can't involve distillation, because my vac-pump was cooked by formic acid.
There is a very reliable way to produce anhydrous HBr, but it might not be for everyone, because I'm guessing that lithium bromide's expensive? Anyway, here's a piece of a patent that gave me a chubby:
US3199953Process For Production Of Anhydrous Hydrogen Bromide From Lithium Bromide Into a turbomixer having approximately a 100ml capacity was charged 61g benzoic acid and 15g (approximately 0.15M) of lithium bromide. The mixture was heated to a temperature in the range 250-260*C with stirring, and nitrogen or carbon dioxide gas at a flow rate of 235ml per minute was passed through the heated mixture. After 1 hour at temperature, approximately 80% of the theoretical amount of hydrogen bromide had been evolved. At 2 hours, 89% of the theoretical hydrogen bromide had been evolved. The reaction is substantially complete after 4 hours of reaction time.

In this reaction, would the lithium bromide be converted to lithium benzoate? How would one go about extracting and re-forming the bromide? Peace!
