THE RESEARCH OF BIODIESEL PRODUCED BY XANTHOCERAS SORBIFLIA BUNGE OIL

The density、acid value、saponification value and molecular weight of Xanthoceras sorbiflia Bunge seeds oil were determined and the technical terms of producing biodiesel by Xanthoceras sorbiflia Bunge seeds oil through esterification with methanol under the catalization of NaOH were investigated,the reaction time 60min,the operation variables used were molar ratio of methanol to oil,catalyst concentration,and temperature;The experimental results indicated that the most favorable reaction conditions are as follows:reaction temperature at 60℃,molar ratio of oil to methanol 1:6,catalyst amount approximately1wt.% compared to Xanthoceras sorbiflia Bunge seeds oil.Biodiesel made by Xanthoceras sorbiflia Bunge seeds oil are analyzed by Infrared spectrum,main properties of biodiesel obtained are examined which are shown to be well confirming to that of diesel 0#,the biodiesel has very similar properties to diesel 0# in China.
