1,2-环氧丁烷选择性加氢制正丁醇

Selective hydrogenation of 1, 2-epoxybutane to n-butanol

考察了金属催化荆与负载催化剂对1,2-环氧丁烷的选择加氢活性。结果表明,以中性或弱碱性的硅胶为载体、钴为加氢活性金属和氧化镁为助剂的负载型催化剂具有良好选择性加氢效果,1,2-环氧丁烷加氢后转化率达到92.37%,正丁醇选择性为89.29%,仲丁醇选择性为3.19%,正丁烷选择性为1.5%,醇醚等副产物的选择性为5.32%。

Activity of metal catalyst and supported catalysts for selective hydrogenation of 1, 2-epoxybu- tane was investigated. The results showed that the catalyst, prepared using neutral or slightly alkaline silica as the support, Co as tile active metal and MgO as the promoter, exhibited good selective hydrogen-ation activity, with 1, 2-epoxybutane conversion of 92.37%, selectivity to n-butanol of 89.29%, to 2-butanol of 3.19% , to butane of 1.5% and to ethanol-ether by-products of 5.32%.
