Abstract
PROCEDE DE FABRICATION D'ACIDE TEREPHTALIQUE A PARTIR DE TEREPHTALATE DE DIMETHYLE COMME PRODUIT INTERMEDIAIRE. A.L'ACIDE TEREPHTALIQUE EST SEPARE A L'ETAT CRISTALLIN DU MELANGE REACTIONNEL A DES TEMPERATURES DE L'ORDRE DE 300C A 150C. B.LA LIQUEUR MERE EST REMPLACEE PAR DE L'EAU DEMINERALISEE. C.LA SUSPENSION OBTENUE, CONSTITUEE D'EAU DEMINERALISEE ET D'ACIDE TEREPHTALIQUE, EST DETENDUE EN UN OU PLUSIEURS ETAGES ET L'ACIDE TEREPHTALIQUE EST OBTENU AU MOYEN D'UNE OPERATION DE SEPARATION SOLIDESLIQUIDE. D.LA LIQUEUR MERE EST REFROIDIE DE TELLE SORTE QUE L'ACIDE TEREPHTALIQUE ENCORE DISSOUS, AINSI QUE LES PRODUITS SECONDAIRES, PRECIPITENT SEPAREMENT OU EN COMMUN, SOIENT SEPARES SOUS FORME DE MATIERES SOLIDES ET SOIENT TRAITES ULTERIEUREMENT TANDIS QU'ON RECUPERE LE METHANOL. FABRICATION DE MATIERES PREMIERES POUR LES POLYESTERS.
