| 摘 要： | 以双三羟甲基丙烷与正辛酸为原料,对甲基苯磺酸为催化剂,采用酸醇酯化法合成了双三羟甲基丙烷正辛酸酯。考察了反应物投料比、反应时间、催化剂用量等对反应的影响。结果证明,最佳反应条件为:酸醇摩尔比4.4∶1,催化剂用量为双三羟甲基丙烷质量的1.0%,带水剂为双三羟甲基丙烷质量的60%,反应温度为120℃,加热回流4 h。在此工艺条件下,产品颜色浅,产率高达97.28%。并用红外光谱、核磁等方法进行了定性分析。

| Abstract: | Di-trimethylolpropane(di-tmp) octanoate was prepared by using di-trimethylolpropane and caprylic acid as raw materials and p-toluenesulfonic acid as catalyst.The effect of the reactants feed ratio,reaction time and amount of catalyst on reaction was studied.The results showed that the optimum reaction conditions were as follows:molar ratio of acid to alcohol is 4.4 ∶1 and catalyst amount is 1.0% percent of the di-tmp and toluene is 60% percent of the di-tmp,the reaction temperature is 120 ℃,and reflux for 4 h.Under this condition,the yield is up to 97.28%.The product was analysed by IR,NMR. |
