Abstract
Disclosed are a catalyst comprising (A) an aluminosilicate molecular sieve comprising a ferrierite phase and (B) a hydrogenation metal component, and a hydroalkylation process using the catalyst. The catalyst and the hydroalkylation process can be used in the production of phenol and/or cyclohexanone from benzene hydroalkylation.
Claims23
A catalyst comprising:
- (A) an aluminosilicate molecular sieve comprising a ferrierite phase;
- and
- (B) a hydrogenation metal component.
A hydroalkylation process comprising:
- contacting a first aromatic compound with hydrogen in the presence of a hydroalkylation catalyst under hydroalkylation conditions to produce an alkylated aromatic compound, wherein the hydroalkylation catalyst comprises an aluminosilicate molecular sieve comprising a ferrierite phase;
- and a hydrogenation metal component.
A process for making phenol and/or cyclohexanone, the process comprising:
- (A) contacting benzene with hydrogen in the presence of a hydroalkylation catalyst under hydroalkylation conditions to obtain a hydroalkylation product comprising cyclohexylbenzene;
- wherein the hydroalkylation catalyst comprises an aluminosilicate molecular sieve comprising a ferrierite phase;
- and a hydrogenation metal component;
- (B) oxidizing at least a portion of the cyclohexylbenzene in the hydroalkylation product to obtain an oxidation product comprising cyclohexylbenzene hydroperoxide;
- and
- (C) cleaving at least a portion of the cyclohexylbenzene hydroperoxide in the oxidation product in the presence of an acid cleavage catalyst to obtain a cleavage product comprising phenol and cyclohexanone.
