1. be that raw material is made saturated mono carboxylic acid and the method that has more than a functional saturated carboxylic acid triglyceride level of acid with the unmodified vegetables oil that contains the unsaturated fatty acids triglyceride level, it is characterized in that comprising the following steps:

  • (a) this unsaturated fatty acids triglyceride level and oxidative compound are reacted in the presence of the catalyzer of the oxidizing reaction of the olefinic double bond that is used for this unsaturated fatty acids, and obtain adjacent glycol as intermediate product;

    (b) make available from the described intermediate product of step (a) and oxygen or oxygenatedchemicals and change into reaction in the presence of the catalyst for reaction of carboxyl at two hydroxyl oxygens that are used for adjacent glycol, and obtain to comprise saturated mono carboxylic acid (i) and have more than a functional saturated carboxylic acid triglyceride level of acid reaction product (ii), described step (b) has 1;

    1 following water/glycol ratio;

    (c) with described saturated mono carboxylic acid (i) with described have more than a functional saturated carboxylic acid triglyceride level of acid (ii) separate.
