There is disclosed a process for the separation of long chain amino acid and long chain dibasic acid, comprising: (1) adding an ammonium salt to the mixture of alkali salts of long chain amino acid and long chain dibasic acid; (2) heating to remove ammonia; and (3) separating long chain amino acid by solid-liquid separation; and (4) acidifying the salt of long chain dibasic acid with an acid to separate long chain dibasic acid.

This invention relates to a process for the purification of dicarboxylic acids obtained from the hydrolysis of carboxylic acid triglycerides having more than one acid functional group. The process comprises in particular the separation of at least some of the glycerine from the hydrolysis product in an aqueous phase, evaporating and/or distilling the resultant organic phase and recovering at least some of the evaporated and/or distilled dicarboxylic acids through at least one crystallisation operation.
