以油酸及甲醇为原料,经过酯化反应先生成油酸甲酯,油酸甲酯进一步与三羟甲基丙烷反应生成三羟甲基丙烷油酸酯。通过实验确定最佳反应条件为:反应温度为160℃,油酸甲酯与三羟甲基丙烷物质的量比为6.5∶1,甲醇钠的用量为总质量的0.5%,反应8h,收率为95.5%。目的产物的结构经红外光谱和核磁氢谱证实。 Oleic acid and methanol as raw materials, after the first esterification reaction into methyl oleate, methyl oleate further with trimethylolpropane reaction of trimethylolpropane oleate. The optimal reaction conditions were as follows: the reaction temperature was 160 ℃, the molar ratio of methyl oleate to trimethylolpropane was 6.5:1, the dosage of sodium methylate was 0.5% of the total mass, the reaction time was 8h, the yield 95.5%. The structure of the target product was confirmed by IR and 1H NMR.
