preparation
weigh 0.1mol of sodium monomethyl carbonate and combine it with 400g of methanol as a solution; Weigh 0.11mol of diethyl sulfate and add it to the solution, the reaction mixture was maintained at 30 ° C. To 120 ° C. Under a pressure of 0 to 2MPa for 18 hours, and specifically, 100 ° C. And 1MPa for 18 hours. The reaction was completed to obtain a methanol solution of sodium ethyl sulfate. The reaction-completed solution is heated at a reduced pressure of less than 6.0kPa and at 50 ° C., after the methanol is distilled and separated, the temperature is increased from 50 ° C. To 100 ° C., and heated for 1 hour, the monomethyl carbonate, dimethyl carbonate, ethyl methyl carbonate, methanol, carbon dioxide and the like are distilled, wherein methanol and carbon dioxide are generated by thermal decomposition of monomethyl carbonate in very small amounts. After the distillation separation was completed, the monohydrocarbyl sulfate ester salt of this example, I .e., sodium ethyl sulfate, was obtained. After detection, the yield was 99.5%, the water content was 0.08%, the pH value of 1:100 aqueous solution was 6.8, the main content of cation chromatography was 99.3%, and the main content of anion chromatography was 99.5%.
production method
ethyl sulfuric acid is formed by reacting with anhydrous ethanol and fuming sulfuric acid at 35 to 36 ° C. Under normal pressure, and then neutralized with sodium carbonate solution (or sodium hydroxide), and sodium sulfate is filtered off to obtain ethyl sodium sulfate.
