异丁烷-丁烯在磷钨酸柱撑水滑石上的烷基化反应

摘要

Tungstophosphoric acid pillar double hydroxides with composition of M2Al-PW12 [M=Zn2+, Co2+, Ni2+, Mg2+] have been synthesized and their catalytic activities for isobutane-butene alkylation were studied. The results showed that M2Al-PW12 had higher initial activity and selectivity of product, but lower deactivation rate than parent H3PW12and the activity of the catalysts and selectivity in alkylation appeared in relation with the kinds of elements in double hydroxide.
