Title (EN) METHOD FOR PRODUCING POROUS CELLULOSE MEDIUM
(FR) PROCÉDÉ DE PRODUCTION DE SUPPORT POREUX EN CELLULOSE
(JA) 多孔質セルロース媒体の製造方法
Abstract:
(EN) Provided is a novel method by which a porous cellulose medium is able to be suitably produced from cellulose acetate. A method for producing a porous cellulose medium, which comprises: a step for preparing a cellulose acetate solution wherein cellulose acetate is dissolved in a solvent; and a step for obtaining a mixed solution by mixing the cellulose acetate solution, a deacetylating agent and a catalyst with each other.
(FR) L'invention concerne un nouveau procédé par lequel un support poreux en cellulose poreux peut être produit de manière appropriée à partir d'acétate de cellulose. L'invention concerne également un procédé de production d'un support poreux en cellulose, qui comprend : une étape consistant à préparer une solution d'acétate de cellulose dans laquelle de l'acétate de cellulose est dissous dans un solvant ; et une étape consistant à obtenir une solution mixte par mélange de la solution d'acétate de cellulose, d'un agent de désacétylation et d'un catalyseur les uns avec les autres.
(JA) セルロースアセテートから多孔質セルロース媒体を好適に製造することができる新規な方法を提供する。セルロースアセテートが溶媒に溶解したセルロースアセテート溶液を準備する工程、及び、前記セルロースアセテート溶液と、脱アセチル化剤と、触媒とを混合して混合溶液を得る工程、を備える、多孔質セルロース媒体の製造方法。
