Abstract: In a method for continuously preparing crude ethylene sulfate, a sulfur trioxide solution is prepared by dissolving sulfur trioxide with a solution A, an ethylene oxide solution is prepared by mixing a solution B with ethylene oxide, the sulfur trioxide solution and the ethylene oxide solution are pre-cooled, and introduced into a set of microchannel reactors for a real-time reaction to obtain a mixed solution containing crude ethylene sulfate, and then a post-treatment process is carried out to obtain crude ethylene sulfate. With the process, the reaction selectivity is good, and a microchannel reaction can accurately control the reaction energy level due to its rapid mixing and timely heat transfer, which greatly reduces the safety risk and effectively avoids the occurrence of side reactions. One-step synthesis is realized, the atomic economic benefits are significantly improved, and thus the process is a typical low-carbon green chemical reaction.
