Abstract

A new process of biodiesel production by transesterification cottonseed oil with ethanol using tetrahydrofuran (THF)as cosolvent was investigated. The result shows that triglyceides and ethanol could easily dissolve each other with THF in reaction mixture. The order of factors effect on conversion is as follows: molar ratio of ethanol/oil >; reaction temperature >; concentration of cosolvent>;reaction time>;amount of catalyst. The maximal conversion of 88.73% was observed after 1.5h with ethanol/oil of 14:1, reaction temperature of 78°C, the amount of KOH of 1.25wt% and the ratio of THF/oil of 1:1.
