Preparation method of ethylene sulfate

The invention discloses a preparation method of ethylene sulfate, and belongs to the technical field of organic synthesis.Ethylene sulfite and hydrogen peroxide are fully mixed and reacted through a static mixer under the catalysis of a catalyst, ethylene sulfate is efficiently and continuously prepared through an oil-water separation unit and an oil phase collection unit, the reaction conversion rate can reach 99.9% or above, and the yield can reach 99.9% or above. The yield reaches 90% or above; compared with the prior art, a continuous reaction model is adopted to replace a traditional kettle type reaction model, the supported Mn/TS-1 is used as a catalyst, and hydrogen peroxide is used as an oxidizing agent, so that the use of noble metal ruthenium is avoided, the product stability is improved, and the production cost is remarkably reduced. 本发明公开了一种硫酸乙烯酯的制备方法，属于有机合成技术领域，本发明中亚硫酸乙烯酯与过氧化氢在催化剂催化下经静态混合器充分混合反应、油水分离单元、油相收集单元高效连续制备硫酸乙烯酯，反应转化率可达到99.9%以上，收率达90%以上；与现有技术相比，采用连续化反应模型替代传统釜式反应模型，使用负载型Mn/TS-1作催化剂和双氧水作氧化剂
