| Abstract: | Plasticizer tributyl citrate was synthesis catalyzed by KC104 resin coated with bimetallic Lewis acid. The optimal reaction conditions are： the ratio of citric acid to n-butanol is 1/4.5, the catalyst quantity is 8% of the weight of tributyl citrate, reaction temperature is reflux temperature, the yield of citric acid is up to 95% and over, the selectivity is up to 98% and over, the plasticized effect approaches to DOP, the catalyst can use long period. |
