摘要
以氧化亚锡为催化剂,由三羟甲基丙烷和棕榈仁油酸合成了三羟甲基丙烷棕榈仁油酸酯。考察了催化剂用量、反应温度、物料配比以及反应时间等对酯化率的影响。得到优化合成工艺条件为:n(棕榈仁油酸):n(三羟甲基丙烷)=2.80:1,催化剂用量为0.050%,反应温度控制在205~210℃,回流反应5.0h。在此条件下,酯化率可达97%。
Trimethylolpropane palmkernelacid ester was synthesized from trimethylolpropane and palmkernelacid using stannous oxide as catalyst.The effects of reaction conditions including catalyst amount,reaction temperature,molar ratio,reaction time on esterrification rate were examined.The optimum reaction conditions were as follows:the amount of catalyst 0.05%base on the total mass of reactants,the n(palmkernelacid):n (trimethylolpropane) =2.80:1,the reaction temperature 205~210℃,the reaction time 5 hours.The esterification rate under optimum conditions reached 97%.
