椰子油单乙醇酰胺丙氧基醚的合成研究

以椰子油单乙醇酰胺、环氧丙烷为原料,进行开环聚合反应合成椰子油单乙醇酰胺丙氧基醚,考察了椰子油单乙醇酰胺丙氧基醚合成的条件,实验表明,在催化剂氢氧化钾用量为反应物总物质的量的0.5%,反应物椰子油单乙醇酰胺与环氧丙烷物质的量比为1：2,反应温度145℃,反应时间3h的条件下,环氧丙烷的转化率可达99.9%。经测试,椰子油单乙醇酰胺丙氧基醚与椰子油单乙醇酰胺的稳泡性能相近,具有黏度低,水溶性好的特点。

Studies on synthesis of coconut oil monoethanolamide propoxy esters

The coconut oil monoethanolamide propoxy esters was prepared from coconut oil monoethanolamide and epoxypropane by polymerization method.The reaction conditions of coconut oil monoethanolamide propoxy esters were investigated.The optimum reaction conditions are obtained as follows： The amount of KOH catlyst is 0.5% to total reactant（mol）,The molar ratio of coconut oil monoethanolamide and epoxypropane is 1：2,reaction temperature was 145℃and reaction time was 3 hours,The conversion rate of epoxypropane was 99.9%.The coconut oil monoethanolamide propoxy esters have lower viscosity Higher water-soluble and similar foam stability compared to the coconut oil monoethanolamide propoxy esters by test.
