摘　　要：以三氧化硫(SO_(3))、环氧乙烷(EO)为原料,以二氯乙烷为溶剂,利用微通道反应器合成了硫酸乙烯酯粗品,经升华得到硫酸乙烯酯纯品,其结构经^(1)HNMR确证,考察了原料配比n(SO_(3))∶n(EO)、反应温度、停留时间和原料质量分数等对硫酸乙烯酯收率的影响。结果表明,在原料配比n(SO_(3))∶n(EO)为1∶1.0、反应温度为0℃、停留时间为30 s、原料质量分数为10%的最佳条件下,硫酸乙烯酯收率为93.2%。Taking sulfur trioxide(SO_(3))and ethylene oxide(EO)as raw materials,and dichloroethane as a solvent,we synthesized the crude ethylene sulfate by microchannel reactor,and obtained pure ethylene sulfate through sublimation.Moreover,we confirmed its structure by^(1)HNMR,and investigated the effects of raw material ratio n(SO_(3))∶n(EO),reaction temperature,residence time,and mass fraction of raw material on the yield of ethylene sulfate.The results show that the yield of ethylene sulfate can reach 93.2%under the optimum conditions as follows:the raw material ratio n(SO_(3))∶n(EO)is 1∶1.0,the reaction temperature is 0℃,the residence time is 30 s,and the mass fraction of raw material is 10%.
