Title (EN) METHOD FOR PURIFYING ACRYLONITRILE
(FR) PROCÉDÉ DE PURIFICATION DE L'ACRYLONITRILE
(JA) アクリロニトリルの精製方法
Abstract: front page image
(EN)Provided is a method that is for purifying acrylonitrile and that contains a step for distilling a solution containing acrylonitrile, hydrogen cyanate, and water using a distillation tower to which a condenser is connected to the overhead. The method contains a step for fixedly maintaining the temperature of the outlet fluid of the condenser.
(FR)L'invention concerne un procédé de purification de l'acrylonitrile, qui contient une étape de distillation d'une solution contenant de l'acrylonitrile, du cyanate d'hydrogène et de l'eau, utilisant une tour de distillation, un condenseur étant raccordé à la tête de distillation. Le procédé contient une étape destinée à conserver de manière fixe la température du fluide de sortie du condenseur.
(JA) 塔頂に凝縮器が接続された蒸留塔を用いて、アクリロニトリル、シアン化水素及び水を含む溶液を蒸留する工程を含むアクリロニトリルの精製方法であって、 前記凝縮器の出口流体の温度を一定に維持する工程を含む方法。
