固体超强酸SO_4^(2-)/ZrO_2-TiO_2催化合成富马酸二甲酯

Synthesis of Dimethyl Fumarate by Solid Superacid ZrO2-TiO2

研究了以SO2-4 /ZrO2 --TiO2固体超强酸为催化剂 ,催化合成富马酸二甲酯 (DMF)的反应。研究了催化剂的制备条件 ,原料配比 ,反应时间 ,催化剂用量等条件对DMF收率的影响。结果表明 :催化剂有较好的催化活性 ,DMF的收率达到91.6 %

Synthesis of dimetyl fumarate(DMF) by esterification of fumaric acid with methanol catalyzed by solid superacid /ZrO2-TiO2 was proposed in the paper. Effects of catalyst preparation,raw material ratio,reaction time on the yield of DMF were investigated.Result showed that the catalyst had good catalytic activity.At optimol reaction conditions,the yield of DMF reaches 91.6%.Reusable experiments of the catalyst showed that /ZrO2-TiO2 had good stability.
