Use of a heterogeneous catalyst acid in the synthesis of ketones alpha, beta-Unsaturated from aldehydes and ketones.

摘要

Use of a heterogeneous catalyst acid in the synthesis of the ketone {}, {} -unsaturated be from aldehydes and ketones. # The invention relates to a process for preparing the ketones {}, {} -unsaturated to be from aldehydes and ketones, using as heterogeneous catalyst a coal fired acidic prepared with sulfuric acid, as described in Spanish patent ES2275415. The use of catalysts in this reaction greatly reduces the reaction time, allows to carry out the process under mild conditions of temperature, thereby increasing the purity of the final product and reducing the production of undesired compounds and, therefore, the overall cost of process.
