摘要：
Although extensive isomerization of 4,4'-diisopropylbiphenyl (4,4'-DIPB) occurred at 300oC over H-mordenite, high selectivity for 4,4'-DIPB among DIPB isomers was observed over silica-modified H-mordenite. This is due to the prevention of the isomerization of 4,4'-DIPB by the deactivation of external acid sites.
