Abstract

CE PROCEDE EST DU TYPE CONSISTANT A PARTIR DE BUTYROLACTONE, LE CAS ECHEANT SUBSTITUEE, A UTILISER UN ALCOOL ET DU CHLORURE DE THIONYLE. SUIVANT L'INVENTION, ON DISSOUT LA BUTYROLACTONE, EVENTUELLEMENT SUBSTITUEE, DANS DES QUANTITES AU MOINS EQUIMOLAIRES D'UN ALCOOL ABSOLU, ON LA FAIT REAGIR AVEC DES QUANTITES AU MOINS EQUIMOLAIRES DE CHLORURE DE THIONYLE ET ON SEPARE ENSUITE LE PRODUIT DU SO QUI S'EST FORME.THIS PROCESS IS OF THE TYPE CONSISTING FROM BUTYROLACTONE, IF NECESSARY SUBSTITUTED, IN USING AN ALCOHOL AND THIONYL CHLORIDE. FOLLOWING THE INVENTION, THE BUTYROLACTONE, POSSIBLY SUBSTITUTED, IS DISSOLVED IN QUANTITIES AT LEAST EQUIMOLAR WITH AN ABSOLUTE ALCOHOL, IT IS REACTED WITH AT LEAST EQUIMOLAR QUANTITIES OF THIONYL CHLORIDE AND THEN IS SEPARATED FROM THE PRODUCT FROM THE PRODUCT. IS FORMED.
