Abstract:
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.

Claim (Index 2):
The process according to  claim 1  comprising, before step a) the steps of:\n 1) reacting the unsaturated carboxylic acid triglycerides with an oxidising agent and a catalyst activating the oxidation reaction of the olefin double bond to obtain an intermediate compound containing vicinal diols, and \n 2) reacting said intermediate compound containing vicinal diols with an oxidising agent containing molecular oxygen and a catalyst activating the oxidation reaction of the vicinal diols to carboxylic groups, obtaining monocarboxylic acids and triglycerides of carboxylic acids having more than one acid functional group; \n 3) separating out a fraction of said monocarboxylic acids obtaining a mixture comprising said triglycerides of carboxylic acids having more than one acid functional group.
