FIELD: chemistry.
SUBSTANCE: invention relates to the field of chemical technology, in particular to a method for producing biodiesel fuel from vegetable oils, and can find application in industries that use diesel engines. Method for producing biodiesel in supercritical dimethyl carbonate includes the methylation of vegetable oil. Process is carried out in one stage using a non-toxic methylating agent (NTMA), and the transesterification is carried out with dimethyl carbonate under supercritical conditions at a temperature of 225–325 °C and pressure of 20–30 MPa for 3–20 minutes.
EFFECT: increase the degree of transesterification of the oil.
