| Abstract: | Catalytic activity of six inorganic salts in the esterification of high acid value oil with methanol was studied. Results showed that catalytic activity of sodium hydrogen sulfate was the best . The optimal parameters of esterification were as follows ： molar ratio of methanol to oil 10： 1 , reaction temperature 70℃, reaction time 300rain and the amount of sodium hydrogen sulfate 4% ,the transformation rate was 90. 5% , use two steps esterification , the transformation rate was 98%. The catalyst could be recovered easily and used repeatedly. |
