Abstract

PROCEDE DE PREPARATION D'ACIDE TEREPHTALIQUE PAR OXYDATION CATALYTIQUE DU P-XYLENE AU MOYEN D'UN GAZ CONTENANT DE L'OXYGENE. ON EFFECTUE L'OXYDATION A TC DANS LE REACTEUR 10, ON SEPARE, DANS LE CYCLONE 40, UNE PARTIE (DE 60 A 98) DE LA LIQUEUR-MERE DU MELANGE D'OXYDATION, PARTIE QUE L'ON RENVOIE AU REACTEUR D'OXYDATION, ON AJOUTE DE L'ACIDE ACETIQUE CHAUD AU RESTE DU MELANGE D'OXYDATION, ON MAINTIENT LA SUSPENSION OBTENUE A UNE TEMPERATURE COMPRISE ENTRE TC ET 240C, ON SOUMET LE MELANGE A UNE PREMIERE LIXIVIATION A UNE TEMPERATURE DE T A 240C, PUIS A UNE SECONDE LIXIVIATION A UNE TEMPERATURE COMPRISE ENTRE 150 ET 220C, ET ON ISOLE L'ACIDE TEREPHTALIQUE. LE PRODUIT OBTENU CONVIENT PARFAITEMENT POUR LA PREPARATION DE POLYESTERS.
