Abstract
Cerium modification of H-mordenite was highly effective for the deactivation of acid sites on external surfaces in the isopropylation of biphenyl. The selectivity for 4,4ʹ-diisopropylbiphenyl (4,4ʹ-DIPB) over unmodified H-mordenite decreased with the increase of reaction temperature because of the isomerization of 4,4ʹ-DIPB at the external acid sites. The isomerization was effectively prevented by the ceria modification of H-mordenites.
