| Abstract: | The catalytic decomposition of cumene hydroperoxide into phenol and acetone with solid acid catalyst was studied.A supported catalyst using β-zeolite as support,phosphotungstic acid as active component and Ti(SO4)2 as promotor showed good catalytic activity and selectivity.Meanwhile,the optimal reaction conditions were investigated.Experimental results showed when the feed proportion was CHP 20%,acetone 78%,and catalyst 2%,the reaction temperature was 60℃,and the reaction time was 4 h,the conversion of cumene hydroperoxide reached 99.5%,and the selectivity to phenol reached 92.6%. |
