Shape selective alkylation of polynuclear aromatics with mordenite-type catalysts: A high yield synthesis of 4,4′-Diisopropylbiphenyl

G. S. Lee; Joseph J. Maj; Stephen C Rocke; Juan M. Garces

Unique dealuminated mordenite zeolites with a high proportion of mesopores behave as shape selective catalysts in the liquid phase alkylation of biphenyl with propylene. Dealumination reduces deactivation and the mesopores enhance diffusion. High yields of 4,4′-diisopropylbiphenyl (> 70%) are observed.
