white to off-white flakes | [Uses]
Triethylamine hydrobromide is used to prepare dimethyl -alfa-diethylaminomaleate by reacting with dimethyl acetylenedicarbosylate. It is involved in the preparation of triphenylpropargylphosphonium bromide. | [Synthesis]
Triethylamine hydrobromide can be obtained by reacting triethylamine with hydrobromic acid:
(C2H5)3N + HBr → [(C2H5)3NH]Br
| [Purification Methods]
Equimolar portions of triethylamine and aqueous solutions of HBr in acetone are mixed with cooling. The precipitated salt is washed with anhydrous acetone and dried in vacuum for 1-2hours. [Odinekov et al. J Chem Soc, Faraday Trans 2 80 899 1984.] Recrystallise it from CHCl3 or EtOH. [Beilstein 4 IV 322.] |
