Abstract:

A process for oxidizing a composition comprising contacting an alkylbenzene of the general formula (I):where Rand Reach independently represents hydrogen or an alkyl group having from 1 to 4 carbon atoms, wherein Rand Rmay be joined to form a cyclic group having from 4 to 10 carbon atoms, the cyclic group being optionally substituted, and Rrepresents hydrogen, one or more alkyl groups having from 1 to 4 carbon atoms or a cyclohexyl group; and (ii) about 0.05 wt % to about 5 wt % of phenol, with oxygen in the presence of a catalyst containing a cyclic imide having the general formula (II):wherein X represents an oxygen atom, a hydroxyl group, or an acyloxy group under conditions effective to convert at least a portion of the alkylbenzene to a hydroperoxide.

International Classification:

C07C 45/53
C07C 37/08

Abstract:

In a process for producing phenol and cyclohexanone, a cleavage feed containing greater than 40 wt % and no greater than 95 wt % cyclohexyl-1-phenyl-1-hydroperoxide, and at least 5 wt % and less than 60 wt % cyclohexylbenzene is mixed with at least phenol, cyclohexanone, water, and sulfuric acid to produce a cleavage reaction mixture containing from 15 wt % to 50 wt % phenol, from 15 wt % to 50 wt % cyclohexanone, from 1 wt % to 10 wt % cyclohexyl-1-phenyl-1-hydroperoxide, from 5 wt % to 60 wt % cyclohexylbenzene, from 0.1 wt % to 4 wt % water, and from 10 wppm to 1000 wppm sulfuric acid. The cleavage reaction mixture is then reacted at a temperature from 30 C. and to 70 C., and a pressure of at least 1 atmosphere for a time sufficient to convert at least 50% of said cyclohexyl-1-phenyl-1-hydroperoxide in said cleavage reaction mixture and produce a cleavage effluent containing phenol and cyclohexanone.

Abstract:

A process for producing phenol and/or cyclohexanone is described in which cyclohexylbenzene is contacted with an oxygen-containing gas under conditions effective to produce an oxidation effluent comprising cyclohexylbenzene hydroperoxide and at least part of cyclohexylbenzene hydroperoxide is contacted with a cleavage catalyst under conditions effective to produce a cleavage effluent containing phenol and cyclohexanone. At least one of the oxidation effluent and the cleavage effluent contains at least one phenylcyclohexanol as a by-product and the process further comprises contacting the phenylcyclohexanol with a dehydration catalyst comprising a molecular sieve of the MCM-22 family under conditions effective to convert at least part of the phenylcyclohexanol to phenylcyclohexene.

C07C 29/60

Abstract:

In a process for producing phenol and/or cyclohexanone, cyclohexylbenzene is contacted with an oxygen-containing gas to produce an oxidation effluent containing cyclohexylbenzene hydroperoxide. At least a portion of the cyclohexylbenzene hydroperoxide is then contacted with a cleavage catalyst to produce a cleavage effluent containing phenol and cyclohexanone and by-products including phenylcyclohexanol. The cleavage effluent or a neutralized product thereof also comprises at least one compound comprising an atom not being carbon, hydrogen or oxygen, which is separated from the cleavage effluent and/or the neutralized product thereof to leave a cleavage fraction lean in the compound comprising an atom not being carbon, hydrogen or oxygen and containing at least a portion of the phenylcyclohexanol. At least a portion of the phenylcyclohexanol is then contacted with a dehydration catalyst comprising a molecular sieve of the MCM-22 type to convert at least a portion of the phenylcyclohexanol to phenyl cyclohexene.

In a process for producing phenol and/or cyclohexanone, cyclohexylbenzene is contacted with an oxygen-containing gas to produce an oxidation effluent containing cyclohexylbenzene hydroperoxide and the cyclohexylbenzene hydroperoxide is then contacted with a cleavage catalyst to produce a cleavage effluent containing phenol and cyclohexanone. At least one of the oxidation effluent and the cleavage effluent also contains at least one by-product selected from phenylcyclohexanols and phenylcyclohexanones and the process further comprises contacting the by-product with a dehydration catalyst to convert the by-product to phenylcyclohexene and hydrogenating the phenylcyclohexene to cyclohexylbenzene. The dealkylation and hydrogenation may be conducted in a single stage.

Abstract:

In a process for producing a cycloalkylaromatic compound, an aromatic compound and a cyclic olefin are contacted with a first catalyst under conditions effective to produce a reaction product comprising the cycloalkylaromatic compound and at least one non-fused bicyclic by-product. The at least one non-fused bicyclic by-product is then contacted with a second catalyst under conditions effective to convert at least a portion of the at least one non-fused bicyclic by-product to a converted by-product.
