| Catalystic Synthesis of Triethyl Citratr by Activated Carbon Supported Ferric Chloride |
| TAO Xian-ping（Department of Chemical Engineering; Nantong Vocational College; Nantong 226007; China） |
| Abstract：The triethyl citrate was prepared from citric acid and ethanol with activated carbon supported ferric chloride as catalyst.Through examining the effect of factors on the yield,the optimum synthesis conditions were as follow: catalyst amount was 8.0 g,molar ratio of citric acid to alcohol was 1 ∶6.0,and reaction time was 9.0 h(based on 0.3mol citric acid).The yield of esterification reached 87.0 %.This catalyst had many advantages such as easy reuse and less pollution to environment. |
| Key words：triethyl citrate; solid acid; catalyst; esterification |
