| Abstract: | The tri n butyl citrate was synthesized by esterification of citric acid with butyl alcohol in the catalysis of p methyl toluenesulfonic acid (PTSA) under microwave irradiation. Under the optimum reaction conditions (citric acid 5.0g, PTSA 0.3g, n butyl alcohol 20ml, microwave irradiation time 30min), the yield of tri n butyl citrate was 91.2%. The reaction was 6 times faster under microwave irradiation than conventional heating. |
