Abstract

Transesterification of soybean oil in supercritical methanol has been carried outin the absence of catalyst. A co-solvent was added to the reaction mixture in order todecrease the operating temperature, pressure and molar ratio of alcohol to vegetable oil.With CO2 as co-solvent in the reaction system, there was a significant decrease in theseverity of the conditions required for supercritical reaction.
