The current industrial preparation of vinyl sulfate is mainly a synthesis method of ethylene glycol and thionyl chloride and a direct addition method of sulfur trioxide and ethylene oxide. The synthesis method of ethylene glycol and thionyl chloride refers to the reaction of ethylene glycol and thionyl chloride to obtain ethylene sulfite as an intermediate, wherein the ethylene sulfite is oxidized by an oxidant to generate ethylene sulfate, and the oxidant mainly comprises sodium hypochlorite, sodium periodate, potassium permanganate and potassium persulfate. When sodium hypochlorite is used as an oxidant, the oxidation reaction is often incomplete, so that the intermediate ethylene sulfite has higher residue, and the product is difficult to purify and separate; when sodium periodate is used as an oxidant, ruthenium trichloride is used as a catalyst, so that the cost is high and the recycling is difficult; when potassium persulfate is used as an oxidant, the reaction selectivity is poor, side reactions are more, the product yield is low, and more three wastes are generated. The method for preparing the vinyl sulfate by directly adding the sulfur trioxide and the ethylene oxide is characterized in that sulfuric anhydride and the ethylene oxide are simultaneously added into dioxane for reaction, and the raw materials used by the method are high in toxicity and volatility, high in pressure in the production process and high in production facilities and safety countermeasures.
