Abstract: Some of the more recent methods of obtaining biodiesel fuel are based on heterogeneous catalysis, which has th of multiple uses of a catalyst. Natural minerals, such as dolomite, opoca, and serpentinites, could be promisin biodiesel synthesis. The purpose of this study was to optimize the reaction conditions for biodiesel synthesis fron oil and methanol using dolomite as a catalyst. Optimum reaction conditions for the transesterification of sunflo methanol, using dolomite calcined at the temperature of 850°C, have been identified: the amount of the catab molar ratio of methanol to oil-8:l, the reaction duration-5 hours and the reaction temperature-60°C. The amo acid methyl esters (FAME) of the sunflower oil obtained-97.6%. FAME is in conformity with the requirements o standard when 500 ppm of antioxidant Ionol and 500 ppm of depressant Infineum R-442 are added. The cold filt point of FAME is reduced to 7°C by adding 500 ppm of Infineum R-442. This product can be used in summer in tl that are placed in Class E, including Lithuania. It has been established that dolomite without regeneration can be I transesterification of sunflower oil by 2 times
