Abstract
L'INVENTION CONCERNE LA DESHYDRATATION DE L'ACETATE DE METHYLE A L'AIDE D'ANHYDRIDE ACETIQUE. CE PROCEDE PEUT S'INTEGRER A UN PROCEDE DE CARBONYLATION DE L'ACETATE DE METHYLE ANHYDRE, QUI PRODUIT L'ANHYDRIDE ACETIQUE NECESSAIRE A LA DESHYDRATATION, ET PLUS GENERALEMENT A UN PROCEDE D'OBTENTION D'ACETATE DE METHYLE PAR ESTERIFICATION D'ACIDE ACETIQUE PAR CHOH DANS UNE ZONE D'ESTERIFICATION, PUIS DESHYDRATATION ET CARBONYLATION DE L'ACETATE DE METHYLE DONNANT DE L'ANHYDRIDE ACETIQUE. SELON LES PROPORTIONS INTRODUITES DANS LE PROCEDE GLOBAL, CELUI-CI PEUT FOURNIR DIVERS INTERMEDIAIRES DE SYNTHESE ORGANIQUE.
