An experimental study of the process of obtaining biodiesel fuel by reaction of transesterification of rapeseed oil in an ethanol medium in supercritical fluid conditions in the temperature range 623 - 653 K, pressure 30 MPa, molar ratios "ethyl alcohol-rapeseed oil" 12: 1, 18: 1. The influence of heterogeneous catalysts on the amount of product obtained is established.
