摘要
Abstract
Glycerin monostearate is currently an important additives, emulsifier and so on in food or medicine fields. In this work, the synthesis process of glycerin monostearate catalyzed by stannic chloride, was studied in the presence of boric acid. The effect of catalyst content and the type of water taking regent were mainly investigated. The result shows that stannic chloride has a high catalytic activity. The optimal technical conditions were established as follows: molar ratio of glycerin to boric acid to stearic acid was 2∶1∶2 ; the amount of catalysts was 1 g; the reaction temperature was 160 ℃. Under the conditions toluene acts as water taking regent, the optimal yield could get to 96%. The sample of the product was analyzed by FITR. The melting point is 54～56 ℃.关键词
