A KINETIC STUDY ON MALENISATION OF SOYBEAN OIL

Malenisation of soybean oil with maleic anhydride was inve stigated.The effect of variations in weight percent ratio of reactants on rate of reaction has been studied. Sodium bisulphate and sodium bisulphite are used as catalys t for the malenisation of soybean oil. The reaction kinetics is estimated for soybean oil � maleic anhydride ranging from 75:25 to 90:10 . T he optimum conditions are found to be 85:15 soybean oil:maleic anhydride weight percent ratio and 2 % catalyst at 230 0 C for 330 minutes with conversion of 82.48% and yield of 95%.
