摘要
将地沟油经热过滤除杂、酸解反应而获得地沟油酸。以地沟油酸、三甲胺水溶液和环氧氯丙烷为反应原料,制备了一种新型的基于地沟油的季铵盐型阳离子表面活性剂。考察了反应温度、反应时间和所使用的反应溶剂对产物收率的影响,得出最佳的反应条件:乙腈为溶剂,在50℃时反应6h,收率为84.8%。中间产物与终产物的化学结构使用傅里叶变换红外光谱进行了表征。
In order to alleviate the harm of waste oil to human health effectively,to turn waste into treasure,the waste oil was filtered by heat to removal the impurities,and then was decomposed through acidolysis to obtain the waste oleic acid.Moreover,the novel cationic surfactant agent was prepared by using waste oleic acid,aqueous trimethylamine and epichlorohydrin as raw materials.The optimum reaction conditions were that the solvent was acetonitrile,the reaction time of 6h,the reaction temperature was 50℃,and the yield was 84.8%.Finally,the chemical structure of intermediate and final products were characterized by FT-IR.
