Abstract
SE PRODUCE DIACETATO DE ETILIDENO, MEDIANTE REACCION DE DIMETIL ETER, ACIDO ACETICO, HIDROGENO Y MONOXIDO DE CARBONO, A TEMPERATURA Y PRESION ELEVADAS, EN PRESENCIA DE UN HALURO DE ALQUILO, Y DE UN CATALIZADOR BIFUNCIONAL, HETEROGENEO, QUE ES ESTABLE FRENTE A LA HIDROGENACION Y COMPRENDE UN POLIMERO INSOLUBLE, QUE PRESENTA HETEROATOMOS CUATERNIZADOS COLGANTES, ALGUNOS DE LOS CUALES ESTAN UNIDOS MEDIANTE ENLACE IONICO, A COMPLEJOS DE METALES DEL GRUPO VIII, ESTANDO UNIDOS LOS RESTANTES HETEROATOMOS, A IODURO. A DIFERENCIA DE LOS PROCESOS DEL ESTADO DE LA TECNICA ANTERIOR, NO SE PRECISA ACELERADOR (PROMOTOR), PARA PRODUCIR LA REACCION CATALITICA, Y LOS PRODUCTOS SE SEPARAN FACILMENTE DEL CATALIZADOR POR FILTRACION. SE PUEDE EMPLEAR METIL ACETATO COMO REACTIVO, EN LUGAR DEL DIMETIL ETER Y EL ACIDO ACETICO.
