Abstract

PROCEDE PERFECTIONNE DE PRODUCTION DE COMPOSES POLYHYDROXYLES 2 A 6C A PARTIR DE LEURS CARBOXYLATES INFERIEURS. LE MELANGE INITIAL, CONTENANT LE CARBOXYLATE INFERIEUR, EST HYDROLYSE PAR DE L'EAU EN 6 EN PRESENCE D'UN CATALYSEUR, CE QUI DONNE EN 18 UN PRODUIT, CONTENANT LE COMPOSE POLYHYDROXYLE, L'ACIDE CARBOXYLIQUE, DE L'EAU ET DES FRAGMENTS DE CATALYSEUR, ET QUI EST DISTILLE EN 20 POUR DONNER UN PREMIER PRODUIT DE TETE 22 CONTENANT L'EAU ET UN PREMIER PRODUIT DE QUEUE 35 CONTENANT LE COMPOSE POLYHYDROXYLE ET L'ACIDE CARBOXYLIQUE; CE PRODUIT 35 EST DISTILLE EN 36 POUR DONNER UN DEUXIEME PRODUIT DE TETE 38 CONTENANT L'ACIDE CARBOXYLIQUE, ET UN DEUXIEME PRODUIT DE QUEUE 46 CONTENANT LE COMPOSE POLYHYDROXYLE ET QUI EST TRAITE, EN 80, POUR EN EXTRAIRE LE COMPOSE POLYHYDROXYLE. APPLICATION : OBTENTION D'ETHYLENE- OU DE PROPYLENE-GLYCOL PRATIQUEMENT EXEMPTS DE SOUS-PRODUITS DIMERES.
