Abstract
Liquid-phase benzylation of benzene by benzyl chloride to diphenylmethane o ver H-ZSM-5, H-gallosilicate(MFI), H-galloaluminosilicate(MFI), H-ferrosili cate(MFI) and H-ferroaluminosilicate(MFI) zeolites at 80(degrees)C has been investigated. A complete or partial substitution of Al in H-ZSM-5 zeolite by Fe or Ga results in a drastic increase in the catalytic activity of the zeolite in the benzylation process. The redox function of the zeolite is re latively more important than its acid function in the benzylation process.
