摘要
在超声波辅助下,以[L-Glu]HSO_(4)离子液体作为催化剂,探究了超声波频率、超声波功率、离子液体用量、醇酸物质的量之比和反应时间对油酸与月桂酸酯化反应的影响.结果表明:在超声波频率为35 kHz,功率为450 W,醇酸物质的量之比为7∶1条件下,当离子液体用量为油酸质量的7.5%,反应时间为21 h时,油酸的转化率达到85.84%;当离子液体用量为月桂酸质量的17.5%,反应时间为18 h时,月桂酸转化率达到92.63%.
The esterification of oleic acid and lauric acid ultrasonic-assisted catalyzed by[L-Glu]HSO_(4) was studied.The effects of ultrasonic frequency,ultrasonic power,ionic liquid dosage,the molar ratio of methanol to acid,and reaction time on the esterification reaction of oleic acid and lauric acid were investigated.The results showed under the conditions of ultrasonic frequency of 35 kHz,power of 450 W and the molar ratio of methanol to acid of 7∶1,the conversion of oleic acid reached 85.84%,when the ionic liquid dosage was 7.5%of the mass of oleic acid and the reaction time was 21 h,and the conversion of lauric acid reached 92.63%,when the amount of liquid was 17.5%of the mass of lauric acid and the reaction time was 18 h.
