摘要：
Alkylation of benzene with 1-alkenes (C6–C18) was performed in liquid phase at 160–200 °C over beta zeolites with Si/A molar ratio 12.5–75.0. With increasing alkyl chain length, the conversion of 1-alkene decreased. The alkylation activity decreased with increasing Si/Al ratio of beta-zeolite. The increase of Si/Al molar ratio was connected with the enhancement of the portion of Lewis acid sites in total acidity of beta zeolites, resulting in greater dimerization/oligomerization activity and consequently in more rapid deactivation of beta-zeolites.
