ABSTRACT:
An improvement to the process for preparing a polyhydric alcohol bromohydrin from the group consisting in the polymethylol-alkanes, penta-erythritols, amino-substituted polyhydric alcohols by the action of hydrobromic acid on the said polyhydric alcohol, consisting of effecting the reaction in an acetic medium with an aqueous solution of hydrobromic acid, eliminating the water during the course of the reaction by distillation of a water-acetic acid mixture rich in water, by means of an apparatus comprising a distillation column adapted to extract vapours at a temperature lower than 103.degree.C, collecting the resultant product, subjecting this latter to a transesterification reaction with a monohydric-alcohol of low molecular weight from the methanol group, and subjecting said product to a purification treatment.
