Transesterification of karanj oil was done in the laboratory of Dept. of Mechanical Engineering and Dept. of Chemistry. In the transesterification process karanj oil was reacted with methanol in the presence of sodium hydroxide to produce glycerol and fatty acid esters (karanj methyl esters) through batch process. Glycerol was drained off while karanj methyl esters were further treated to remove impurities and to have fuel grade biodiesel. Each batch thus produced was tested for purity.
