| Abstract: | Studies were carried out on transesterification of waste oil with butyl alcohol catalyzed by the solid acid for the production of fatty acid butyl esters.The effects of different factors such as mole ratio of reactants,catalyst dosage,reaction temperature and reaction time on the conversion rate of fatty acid butyl esters were investigated.Products were analyzed by infrared spectroscopy method.A study for optimizing the reaction conditions for the transesterification of waste oil was performed.Under the optimum conditions of mole ratio of butyl alcohol to waste oil of 16∶1,1.2% catalyst based on the total mass of the reactant,reaction temperature1 of 115 ℃ and reaction time of 4 hours.Then the conversion rate of fatty acid butyl esters from waste oil was over 83%. |
