The transesterification of rapseed oil was studied in supercritical methanol with and without catalyst. For a preheating temperature of 350 degree C, 240 s of supercritical treatment of methanol was sufficient to convert rapeseed oil to methyl esters. The prepared methyl esters were virtually the same as those obtained by the more conventional route with a basic catalyst but the yield without catalyst was higher than with. Merits of this new process include shorter reaction time and simpler purification of end-products since no catalyst is used.
