Abstract:
1. Process for the production of saturated monocarboxylic acids and triglycerides of saturated carboxylic acids having more than one acid function starting from non-modified vegetable oil containing triglycerides of unsaturated fatty acids, characterised in that it comprises the steps of (a) reacting the triglycerides of unsaturated fatty acids with an oxidizing compound in the presence of a catalyst for the oxidization reaction of the olefinic double bond of the unsaturated fatty acid and obtaining a vicinal diol as intermediate reaction product; (b) reacting said intermediate product obtained from step (a) with oxygen or a compound containing oxygen, in the presence of a catalyst for the oxidation reaction of the two hydroxyl groups of the vicinal diol to carboxylic groups, and obtaining a reaction product comprising saturated monocarboxylic acids (i) and triglycerides of saturated carboxylic acids having more than one acid function (ii), said step (b) having a water/diol ratio of below 1:1; (c) separating said saturated monocarboxylic acids (i) from said triglycerides of saturated carboxylic acids having more than one acid function (ii).
