Abstract

Procédé pour produire d'une manière efficace et rapide des esters de cellulose d'acides organiques. Ce procédé comprend une étape de confrication de la cellulose en présence de produits chimiques d'estérification, cette étape de confrication fournissant la force motrice majeure dans la conduite de la réaction d'estérification. Application à la préparation d'acétate de cellulose.
