All kinds of liquid hydrocarbonic fuel possess low specific electroconductivity and are inclined to intensive electrization. Liquid hydrocarbons are capable to keep an electrostatic charge in volume during long time. In connection with that formation of charges of a static electricity are in direct dependence on speed of streams of mineral oil frequently in order to prevent explosions and fires to have to limit speed of movement of a stream that finally results in sharp decrease in intensity of technological operations with mineral oil. As it is established, the most effective means of decrease in specific electric resistance of a liquid and by that liquidation of accumulation of charges of a static electricity is additions to oil and mineral oil of antistatic additives. Under action of an additive there is an increase specific volumetric, electroconductivity hydrocarbonic system as a result of which there is a relaxation of charges between a place of their formation and a place where presence of charges causes the greatest danger. As such an additive is offered the big number of connections which basically concern to a category of organic salts and complexes. At creation of antistatic additives it is necessary to take into account that some organic complexes especially containing in the structure inorganic anion or molecules of water, are badly dissolved in hydrocarbonic fuels. We synthesize various salts of oil acids from Baku oils. Reactions have been lead in the hydrocarbonic environment and consequently into structure of received salts do not enter inorganic anions. Thus, have been received Ca, Zn, Mn, Ba, Cu, Ni, Pb and Cr-salt of natural oil acids. Additives have been added to the diesel fuel received from Baku oils within the limits of 0.0002-0.3 % of weights. As a result of the realize researches it has been established, that among salts of a distilled oil acid higher antistatic property chromic and nickel salts possess.
