Abstract

SE DESCRIBE UN NUEVO PROCEDIMIENTO PARA LA PREPARACION DE DIESTERES DEL ACIDO TEREFTALICO Y DE DIOLES DE POLIESTERES. EL PROCEDIMIENTO SE CARACTERIZA POR UNA DESPOLIMERIZACION DEL POLIESTER EN PRESENCIA DE CATALIZADORES DE TRANSESTERIFICACION PARA DICHOS POLIESTERES, Y EN PRESENCIA DE UN ESTER, SEGUIDO DE UNA TRANSESTERIFICACION DE LA MEZCLA REACTIVA PARA DAR EL DIESTER DEL ACIDO TEREFTALICO POR REACCION CON UN ALCOHOL MONOVALENTE. POR MEDIO DEL NUEVO PROCEDIMIENTO PUEDEN RECUPERARSE LOS COMPONENTES DE PARTIDA DE LOS POLIESTERES DE FORMA RAPIDA Y BAJO UNAS CONDICIONES DE REACCION SUAVES.
