Abstract
SE PRESENTA UN PROCESO PARA PRODUCIR UN ESTER DE ACIDO CARBOXILICO ALFA , BETA-INSATURADO QUE COMPRENDE LA REACCION CATALITICA DE UN ESTER DE ACIDO ALFA-HIDROXICARBOXILICO CON UN CATALIZADOR DE ALUMINOSILICATO CRISTALINO, Y LA POSTERIOR REACCION CATALITICA DEL PRODUCTO DE REACCION RESULTANTE CON UN CATALIZADOR ACIDO SOLIDO. DE ACUERDO CON EL PROCESO, SE PUEDE PRODUCIR UN ESTER DE ACIDO CARBOXILICO ALFA, BETA-INSATURADO DE UNA ALTA PUREZA Y UNA GRAN CALIDAD, DE FORMA ALTAMENTE EFICIENTE.
