1. A METHOD FOR PRODUCING LITHIUM BROMIDE, beginning by refining a lithium carbonate suspension with an aqueous bromide in the presence of an inorganic reagent, the subsequent separation of mixture from sediment, it's evaporation and crystallization from the product, differentiated so, that, the cost of the process  is deliberately lowered by enhancing yields and conserving the basic qualitative product.  As an inorganic reagent ammoniated water is used.
2. Re: Method no. 1, it is significant that ammoniated water is used at a concentration of 25-30%
3. Re: Method no. 1, it is significant that the refinement with aqueous bromide is initiated at a rate of 60-90 liters/hour maintaining lithium carbonate ratio in the reactive mass at 60-90 grams/liter.  After that a rate of 30-50 liters/hour in the presence of said lithium carbonate.

Damn, I didn't know that producing lithium bromide would be that much of a pain in the ass. Boiling it with benzoic acid produces HBr, so it's worth it!

Bwiti,

Damn, I didn't know that producing lithium bromide would be that much of a pain in the ass

You could simple try this one:
Li2CO3 + 2HBr -> 2 LiBr + H2O + CO2
evap water until cristalls appear, suction filter, dry in evac desic, put in thightly sealed bottle because it's a bit hygroscopic.

Carpe Diem

"it's a bit hygroscopic."

  If I can keep methylamine hydrochloride dry, then lithium bromide won't be a problem.
  Hmmmm, how much does benzoic acid cost these days? 10oz for like $12? Pet ether's cheap..Fuck making bromosafrole with DMSO; Smells like human waste and rotten milk. Peace!
