Disclosed are a process for abating 3-cyclohexenone from a feed mixture comprising 3-cylclohexenone and cyclohexanone, comprising a hydrogenation step of contacting the feed mixture with hydrogen in the presence of a hydrogenation catalyst under hydrogenation conditions to obtain a hydrogenated mixture, cyclohexanone-containing products comprising 3-cyclohexenone and/or 2-cyclohexenone at low concentrations, and compositions of matter useful for making such cyclohexanone-containing products, particularly by using such processes.

The present disclosure relates to a process for acid-catalyzed decomposition of aryl -hydroperoxide with a continuous flow tubular reactor. The process is a novel process performed in a tubular reactor, taking the aryl -hydroperoxide such as cumene hydroperoxide (CHP) as a raw material and taking acids as a catalyst, performing acid-catalyzed decomposition of the aryl -hydroperoxide solution in a short reaction time ranging from tens of seconds to several minutes, thereby obtaining the phenols; wherein an inert component may be filled in the reactor, so that the effects of heat transmission and mass transfer can be enhanced. The aryl -hydroperoxide and acid are respectively introduced by a metering pump into a mixing module to be mixed, and then enter the tubular reactor to be reacted so as to produce the products such as phenols.
