description The invention relates to an ethylene sulfate preparation method, which comprises: (1) dissolving a first raw material ethylene sulfite in an organic solvent to obtain a first intermediate material; (2) dispersing a second raw material sulfur trioxide into the first intermediate material and then reacting to obtain a second intermediate material; (3) removing low-boiling-point substances from the second intermediate material to obtain a concentrated solution; and (4) contacting the concentrated solution with an extraction agent for extraction, and removing the extraction agent in the obtained extraction solution to obtain ethylene sulfate. According to the preparation method of the ethylene sulfate, the ethylene sulfate is synthesized by taking the ethylene sulfite and the sulfur trioxide as raw materials through reaction, the high-purity ethylene sulfate is prepared at high yield, and the preparation method is suitable for large-scale industrial production. 本发明涉及一种硫酸乙烯酯的制备方法，该制备方法包括如下步骤：(1)使第一原料亚硫酸乙烯酯溶解于有机溶剂中
