Title (EN) PROCESSES FOR MAKING CYCLOHEXANONE
(FR) PROCÉDÉ DE PRODUCTION DE CYCLOHEXANONE
Abstract:
(EN) Disclosed are processes for abating 3-cyclohexenone from a feed mixture comprising cyclohexylbenzene, cyclohexanone, phenol, and 3-cylclohexenone and cyclohexanone, comprising feeding the feed mixture to a first distillation column and a hydrogenating a fraction from in the presence of a hydrogenation catalyst under hydrogenation conditions. Hydrogenation can be carried out in a hydrogenation reactor separate from the first distillation column or in a hydrogenation zone disposed inside the first distillation column.
(FR) L'invention concerne des procédés de réduction de la 3-cyclohexénone à partir d'un mélange d'alimentation comprenant du cyclohexylbenzène, de la cyclohexanone, du phénol, et de la 3-cyclohexénone et de la cyclohexanone, comprenant l'alimentation du mélange d'alimentation dans une première colonne de distillation et l'hydrogénation d'une fraction en présence d'un catalyseur d'hydrogénation dans des conditions d'hydrogénation. L'hydrogénation peut être effectuée dans un réacteur d'hydrogénation séparé de la première colonne de distillation ou dans une zone d'hydrogénation disposée à l'intérieur de la première colonne de distillation.
