Title (EN) METHOD FOR PRODUCING ALCOHOL COMPOUND
(FR) PROCÉDÉ DE PRODUCTION D'UN COMPOSÉ ALCOOL
(JA) アルコール化合物の製造法
Abstract:
(EN) A method is provided by which an alcohol compound having a satisfactory purity is obtained from an ester compound in a simple manner. A high-purity alcohol compound can be obtained by: passing a solution which contains both an ester compound and methanol and/or ethanol through a column packed with an anion-exchange resin which has a methoxide or ethoxide as a counter anion, thereby yielding a methyl ester and/or an ethyl ester; and distilling off the ester(s) together with the methanol and/or ethanol.
(FR) L'invention concerne un procédé par lequel un composé alcool ayant une pureté satisfaisante est obtenu à partir d'un composé ester d'une manière simple. Selon l'invention, un composé d'alcool de haute pureté peut être obtenu par le procédé consistant à : faire passer une solution contenant à la fois, un composé ester et du méthanol et/ou de l'éthanol à travers une colonne remplie d'une résine échangeuse d'anions qui a un méthoxyde ou un éthoxyde en tant que contre-anion, ce qui permet d'obtenir un ester méthylique et/ou un ester éthylique ; et distiller l'(les) ester(s) conjointement avec le méthanol et/ou l'éthanol.
(JA) エステル化合物からアルコール化合物を純度よく、且つ簡便な操作で取得する方法を提供する。 エステル化合物とメタノール及び/又はエタノールを含む溶液を、メトキシド又はエトキシドをカウンター陰イオンに持つ陰イオン交換樹脂を充填したカラムに通液して、メチルエステル及び/又はエチルエステルを生成させ、これをメタノール及び/又はエタノールと一緒に留去することで、高純度のアルコール化合物が取得できる。
