BF_(3)-H_(3)PO_(4)/ZrO_(2)催化异丁烷和丁烯烷基化反应

BF_(3)-H_(3)PO_(4)/ZrO_(2) Catalyst for Isobutane-Butene Alkylation

BF_(3)和H_(3)PO_(4)的分子化合物可用于异构烷烃和烯烃烷基化。BF_(3)-H_(3)PO_(4)-SbF_(5)可使异戊烷和乙烯烷基化得高辛烷值燃料,但这些都是液相酸,无现实意义。

In this paper,isobutane-butene alkylation has been studied by using BF_(3)-H_(3)PO_(4)/ZrO_(2) as a catalyst.It was found that the catalyst 404 showed high activity,selectivity and stability at 100℃,1 atm.and with an isoparaffin to olefin ratio of 6.5:1.
