FIELD: chemistry.
SUBSTANCE: method involves preparation of plant oil with heating to 80°C, alkaline ethanolysis using potassium hydroxide in ethanol with molar concentration of 2 mol/dm3 to obtain an ether-glycerine mixture which is separated to form two fractions - glycerine and a mixture of ethers. The mixture of ethers (biodiesel fuel) undergoes filtration, sorption purification and dehydration. The obtained biodiesel fuel is stored. Preparation of the plant oil is carried out such that before heating, the plant oil is mixed with 1% aqueous solution of an Ecofriend enzyme-probiotic preparation and the obtained mixture is held for 24 hours at temperature 23-27°C. After holding for 24 hours, the mixture of plant oil and this preparation is heated to said heating temperature. The products are taken in the following ratio, pts.wt: plant oil 5; 1% aqueous solution of Ecofriend enzyme-probiotic preparation 5; potassium hydroxide in ethanol 5.
EFFECT: method increases the amount of the obtained biodiesel fuel.
