In the synthesis of hemiesters, maleic anhydride is used as a catalyst, resulting in a mild reaction and a light product color. The operation is as follows: add lauryl alcohol polyoxyethylene (3) ether to the reactor, add nitrogen gas, and heat up for dehydration. After dehydration is qualified, cool to 60 ℃, add a certain amount of maleic anhydride as a catalyst, stir evenly, and then add concentrated sulfuric acid in the amount of lauryl alcohol polyoxyethylene (3) ether and other substances. Measure the initial acid value, and heat up the reaction for a certain time to obtain the semi esterification product. In another reactor, add deionized water, raise the temperature to 80 ℃, and under nitrogen protection, add a semi ester. Dissolve completely and neutralize with triethanolamine. Filter, package, and obtain finished products.
