Title
(EN) METHOD FOR RECOVERY OF FLUORINATED ALCOHOL
(FR) PROCÉDÉ DE RÉCUPÉRATION D’ALCOOL FLUORÉ
(JA) 含フッ素アルコールの回収方法
Abstract
(EN)
A method for recovering a fluorinated alcohol comprising the step of adding an inorganic salt to a mixed solution comprising the fluorinated alcohol and water to cause two-phase separation. This method can recover a fluorinated alcohol by separating water from a mixed solution of the fluorinated alcohol and water which is produced during a CD-R or DVD-R production process.
(FR)
La présente invention concerne un procédé pour la récupération d’alcool fluoré qui comprend une étape d’ajout d’un sel inorganique à une solution mixte comprenant de l'alcool fluoré et de l'eau pour provoquer une séparation en deux phases. Ce procédé peut récupérer un alcool fluoré par séparation de l'eau d'une solution mixte d'alcool fluoré et d'eau qui est produite durant un procédé de fabrication de CD-R ou de DVD-R.
(JA)
 CD-RやDVD-Rの製造によって発生する、含フッ素アルコールと水とを含有する混合液から水を分離し、含フッ素アルコールを簡便に回収する方法を提供する。  含フッ素アルコールおよび水を含有する混合液に無機塩を添加し、2層分離させる工程を有することを特徴とする含フッ素アルコールの回収方法。
