Disclosed are processes for abating 3-cyclohexenone from a feed mixture comprising cyclohexylbenzene, cyclohexanone, phenol, and 3-cyclohexenone 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.
