Preparation of biodiesel from rapeseed via extraction and in-situ transesterification in supercritical methanol was discussed.The main components of the biodiesel were methyl linoleate,methyl oleate,methyl palmitate,methyl stearate and methyl linolenate.Reaction temperature, reaction pressure and mass ratio of rapeseed to methanol had an important effect on the conversion of the rapeseed oil.The 94.3% oil conversion can be achieved at 280℃ and 14 MPa within 10 min at the mass ratio of rapeseed to methanol of 1:4.
