  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. |  [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.
