摘要：

Gallosilicate and antimonosilicate catalysts modified with a small amount of boron oxide exhibited perfect para-selectivities for the alkylation of ethylbenzene with ethanol. Moreover, the alkylation activities of these zeolites were high compared with that of modified H-ZSM-5, which also exhibits a perfect para-selectivity. The improvement in para-selectivity as a result of the modification is not due to the reduction in effective pore dimension but rather to the reduction in acid strength of MFI zeolites.
