COATING TO INHIBIT FOULING OF REACTORS FOR CUMENE HYDROPEROXIDE CLEAVAGE

The disclosure concerns methods comprising forming a phenol and acetone mixture from decomposition of a cumene hydroperoxide or a phenol, acetone, and AMS from the decomposition of a mixture containing dicumyl peroxide in a system comprising one or more reactors where at least a portion of an inner surface of the one or more reactors has a polymer coating and wherein the coating inhibits build-up of a fouling precipitate on the coated inner surface of the one or more reactors as compared to such build-up in the absence of the coating.

Hydroalkylating process comprising an activation of the hydroalkylation catalyst and method of making phenol and cyclohexanone

Disclosed is a hydroalkylation process in which the hydroalkylation catalyst is activated in the presence of a flowing fluid comprising hydrogen and a condensable agent. The presence of the condensable agent enables fast, effective activation of the hydroalkylation catalyst precursor in a cost-effective manner. It also yields superior catalyst performance.

Processes for producing phenol

Disclosed herein is a process for producing phenol. The process includes oxidizing at least a portion of a feed comprising cyclohexylbenzene to produce an oxidation composition comprising cyclohexyl-1-phenyl-1-hydroperoxide. The oxidation composition may then be cleaved in the presence of an acid catalyst to produce a cleavage reaction mixture comprising the acid catalyst, phenol and cyclohexanone. At least a portion of the cleavage reaction mixture may be neutralized with a basic material to form a treated cleavage reaction mixture. In various embodiments, the treated cleavage reaction mixture contains no greater than 50 wppm of the acid catalyst or no greater than 50 wppm of the basic material.
