Abstract

PROCEDIMIENTO CONTINUO PARA LA OBTENCION DE UN MALEATO DE DIALQUILO PRACTICAMENTE EXENTO DE ACIDO, P.EJ. MALEATO DE DIETILO, PARTIENDO DE UNA CORRIENTE DE ALIMENTACION QUE CONTIENE UNA CANTIDAD IMPORTANTE DE MALEATO DE DIALQUILO Y UNA CANTIDAD MENOR DEL CORRESPONDIENTE MALEATO DE MONOALQUILO. EL PROCEDIMIENTO CONSISTE EN DESTILAR EN FORMA CONTINUA LA CORRIENTE DE ALIMENTRACION EN UNA ZONA PRIMARIA DE DESTILACION QUE PUEDE CONSISTIR EN UNA SOLA COLUMNA DE DESTILACION O EN UN CONJUNTO DE ESTAS CONECTADAS EN SERIE, PARA DAR (I) UNA FRACCION DE FONDO QUE CONTIENE MALEATO DE MONOALQUILO Y MALEATO DE DIALQUILO MEZCLADOS (II) UNA FRACCION EN FORMA DE VAPOR QUE CONTIENE ALCANOL Y (III) UNA FRACCION INTERMEDIA PRACTICAMENTE EXENTA DE ALCANOL Y CONTIENE UNA PROPORCION ALTA DE MALEATO DE DIETILO Y UNA CANTIDAD MENOR DE ANHIDRIDO MALEICO. LA FRACCION INTERMEDIA (III) SE REDESTILA EN UNA ZONA SECUNDARIA DE DESTILACION PARA PRODUCIR (I) UNA FRACCION DE CABEZA QUE CONTIENE ANHIDRIDO MALEICO Y (II) UNA FRACCION DE FONDO QUE CONTIENE MALEATO DE DIALQUILO EXENTO DE ACIDO. LA CORRIENTE DE VAPOR PUEDE CONDESARSE PARA RECUPERAR ALCANOL PARA RECICLARLO A UNA INSTALACION DE PRODUCCION DE MALEATO DE DIALQUILO.
