Abstract
L'INVENTION CONCERNE LA PREPARATION DE 1,1-DIESTERS. LES 1,1-DIESTERS SE PREPARENT PAR LA MISE EN OEUVRE D'UN PROCEDE HETEROGENE CONFORMEMENT AUQUEL ON MET UN ANHYDRIDE CARBOXYLIQUE EN CONTACT AVEC DE L'HYDROGENE, EN PRESENCE D'UN CATALYSEUR D'HYDROGENATION EN METAL INSOLUBLE ET D'UN ACIDE PROTONIQUE FORT. LE PROCEDE SELON L'INVENTION DONNE DES RENDEMENTS BIEN PLUS ELEVES QUE LES PROCEDES DE LA TECHNIQUE ANTERIEURE.
