Abstract

L'INVENTION CONCERNE DES PERFECTIONNEMENTS A LA PREPARATION DES ALKYLENE-GLYCOLS. LE LIQUIDE IMPUR 18 A TRAITER CONTIENT DE L'ETHYLENE- OU DU PROPYLENE-GLYCOL, DES CARBOXYLATES INFERIEURS DE GLYCOL, HO, UN ACIDE CARBOXYLIQUE ET UN AGENT FORMANT UN MELANGE AZEOTROPE AVEC LE GLYCOL; ON ELIMINE LA QUASI-TOTALITE DE CET AGENT EN DISTILLANT LE LIQUIDE IMPUR DANS UNE ZONE DE DISTILLATION 20 POUR FORMER UN PRODUIT DE TETE 23 (CONTENANT DE L'EAU ET DE L'AGENT) ET UN PRODUIT DE QUEUE 35 (CONTENANT LE GLYCOL, LES ESTERS ET L'ACIDE CARBOXYLIQUE, SANS CET AGENT MAIS COMPORTANT AU MOINS 1 ENVIRON DU POIDS DE L'EAU INTRODUITE AVEC LE LIQUIDE IMPUR DANS LA ZONE DE DISTILLATION). LES GLYCOLS PURIFIES PEUVENT SERVIR DANS DES COMPOSITIONS ANTIGEL, POUR FABRIQUER DES FIBRES DE POLYESTER, ETC.
