摘　　要：以棕榈油为原料进行常压酸催化水解工艺研究。考察了反应时间、反应温度、催化剂用量、油水质量比及乳化剂用量对棕榈油水解反应的影响,得出棕榈油一次酸催化水解的最佳反应条件:反应时间7 h,反应温度100℃,催化剂浓硫酸用量7.5%,油水质量比1∶1,乳化剂磺酸用量0.5%;在最佳反应条件下棕榈油水解产物酸值(KOH)为192.77 mg/g,水解率达到91.96%。并研究出一套循环水解的工艺流程,实现油脂水解产物的循环利用,提高了水相中甘油的含量。The hydrolysis of palm oil catalyzed by acid was studied. The effects of reaction time, reaction temperature, catalyst dosage, mass ratio of oil to water and emulsifier dosage on the hydrolysis of palm oil were investigated. The optimal reaction conditions of palm oil hydrolysis were obtained as follows ： reaction time 7 h,reaction temperature 100 ℃ ,mass ratio of oil to water 1：1 ,dosage of sulfonic acid used as emul- sifier 0.5% and catalyst（ concentrated sulfonic acid） dosage 7.5%. Under the optimal reaction condi- tions,the acid value of the hydrolysates was up to 192.77 mgKOH/g and the hydrolysis rate of palm oil was 91.96%. A circulated hydrolysis process was designed, then the recycling of hydrolysates was real- ized, and the content of glycerin in the aqueous phase increased.
