Abstract
Tributyl citrate was synthesized with citric acid and n-butyl alcohol as raw materils using p-toluene sulphonic acid supported on active carbon as catalyst.The optimum conditions of synthesis were determined:molar ratio of acid to alcohol is 1∶4.1,amount of catalyst is 0.6 g,reaction time is 3h based on 0.1 mol tributyl citrate,the yield of esterification is up to 96.7%.
