Abstract

L'INVENTION CONCERNE L'HYDROLYSE DE CARBONATES D'ALKYLENE EN ALKYLENEGLYCOLS. DES GLYCOLS DE FORMULE HOCHRCHOH SONT PRODUITS PAR HYDROLYSE, DANS UN MELANGE HOMOGENE EN PHASE LIQUIDE, D'UN CARBONATE D'ALKYLENE DE FORMULE: (CF DESSIN DANS BOPI) DANS LAQUELLE R EST UN ATOME D'HYDROGENE OU UN GROUPE METHYLE. L'OPERATION EST CONDUITE EN UTILISANT UNE QUANTITE D'EAU EN EXCES PAR RAPPORT A LA STOECHIOMETRIE ET EN UTILISANT DE PREFERENCE LE CARBONATE DE POTASSIUM COMME CATALYSEUR. LA REACTION EST CONDUITE SOUS PRESSION MANOMETRIQUE DE CO D'AU MOINS 5,6BARS ET LA TEMPERATURE DE REACTION EST AVANTAGEUSEMENT COMPRISE ENTRE ENVIRON 85 ET 500C. LE PROCEDE DE L'INVENTION PEUT ETRE UTILISE POUR PRODUIRE DE L'ETHYLENEGLYCOL DE QUALITE POUR FIBRES EN POLYESTERS.
