| titleOfInvention | Process for preparing mono- and dicarboxylic acids from unsaturated fatty acids and/or their derivatives |
| abstract | The present invention relates to a process for the preparation of carboxylic acids from unsaturated fatty acids and / or their derivatives.n n n une étape qui consiste à oxyder un acide gras insaturé sous forme d'acide et/ou d'ester par le peroxyde d'hydrogène, en présence d'un oxyde métallique ou d'un acide carboxylique éventuellement associé à un catalyseur à base de ruthénium, une étape qui consiste à faire réagir le milieu réactionnel issu de l'étape précédente, avec de l'acide nitrique en présence d'un catalyseur à base de vanadium, éventuellement associé à un co-catalyseur, puis une étape de récupération des acides mono- et dicarboxyliques. The method of the invention is characterized in that it comprises the following steps: a step which consists in oxidizing an unsaturated fatty acid in the form of an acid and / or of an ester with hydrogen peroxide, in the presence of a metal oxide or a carboxylic acid optionally combined with a ruthenium-based catalyst , a step which consists in reacting the reaction medium resulting from the previous step, with nitric acid in the presence of a vanadium-based catalyst, optionally combined with a cocatalyst, then a step of recovery of mono- and dicarboxylic acids. n n n It is particularly well suited for the preparation of saturated mono- and dicarboxylic acids obtained from unsaturated fatty acids such as oleic acid or from oils and fats. |
