【摘要】 <正> BF₃和H₃PO₄的分子化合物可用于异构烷烃和烯烃烷基化。BF₃-H₃PO₄-SbF₅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。 BF₃有强夺电子特性,使BF₃-H₃PO₄具有极强的酸性。将此酸载于ZrO₂上,使其固相化,酸强度为-8.2≤H₀≤-5.6。经XPS的测试和IR剖析,推测此固体酸含更多还原

【Abstract】 In this paper, isobutane-butene alkylation has been studied by using BF₃-H₃PO₄/ZrO₂ 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.更多还原
