Process for acid-catalyzed decomposition of aryl α-hydroperoxide with continuous flow tubular reactor

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.

Method of synthesizing cyclohexanone

A method of synthesizing cyclohexanone can include oxidation of cyclohexane to produce a mixture including cyclohexanone, cyclohexanol, and cyclohexane, and separating cyclohexanone from the mixture using a pervaporation method. The pervaporation method includes contacting the mixture with a first side of a poly(styrene-maleic anhydride-dihydropyrane) membrane and receiving the cyclohexanone from a second side of the poly(styrene-maleic anhydride-dihydropyrane) membrane as a low-pressure vapor. The method can be performed in a pervaporation unit including a reactant portion for receiving the cyclohexane, a permeate portion for receiving the cyclohexanone, and a poly(styrene-maleic anhydride-dihydropyrane) membrane separating the reactant portion from the permeate portion.
