Abstract
The possibility of using Na2В4O7 and Na2В4O7∙10H2O as catalysts for transesterification of triacyl glycerides (with sunflower oil as example) with methanol to obtain biodiesel fuel was examined. At the molar ratio of sunflower oil to methanol of 1 : 12, temperature of 65°С, reaction time of 2 h, and catalyst concentration of up to 5 wt %, the maximal yield of the methyl esters of the fatty acids was 65 and 95% with Na2В4O7∙10H2O and Na2В4O7, respectively. Na2В4O7 can be used as a triglyceride transesterification catalyst no less than three times without appreciable change in the yield of fatty acid methyl esters. Na2В4O7 can be recommended as a catalyst for transesterification involving other esters and alcohols.
