Abstract
A process of preparation of carboxylic acids by oxidative cleavage of compounds having substituted or non-substituted, linear or branched, saturated or unsaturated alkyl chains containing at least one vicinal diol or an epoxide in the presence of an oxidant comprising molecular oxygen and a heterogeneous catalyst comprising a copper oxide.
Claims7
Process for the preparation of carboxylic acids comprising
- subjecting to oxidative cleavage compounds having substituted or non-substituted, linear or branched, saturated or unsaturated alkyl chains containing at least a vicinal diol or epoxide in the presence of an oxidizing agent comprising molecular oxygen and a heterogeneous catalyst consisting of a copper oxide in supported form, a copper ferrite or solid solutions between two metal oxides of Cu and Fe of variable composition or a mixture thereof, wherein the support of said copper oxide is selected from the group consisting of:
- alumina, silica, CeO2, TiO2 and a mixture of two or more thereof.
