| Abstract: | The solid base KOH/Al2O3 was used as catalyst to catalyze esterification of polyglycerol and fatty acids of camphor tree seed kernel oil to synthesize polyglycerol medium chain fatty acid ester.The effects of reaction temperature,reaction time,mass ratio of polyglycerol to medium chain fatty acid and dosage of catalyst on esterification rate were studied by single factor tests,and the synthesis technology of polyglycerol medium chain fatty acid ester was optimized by an orthogonal test.The optimal synthesis conditions were as follows: reaction temperature 220 ℃,reaction time 2.5 h,mass ratio of polyglycerol to medium chain fatty acid 2∶ 1,dosage of catalyst 4.5%.Under the optimal conditions,the esterification yield reached 87.5%,and the acid value,saponification value,iodine value,and melting point of the product were 1.86 mgKOH/g,148.4 mgKOH/g,2.9 gI/100 g and 47.3 ℃,respectively. |
| Keywords: | camphor tree seed kernel oil polyglycerol solid base polyglycerol medium chain fatty acid ester |
