Claims (3)

1. The method of producing metal carboxylates in one stage by the interaction of a carboxylic acid and a metal hydroxide in an aqueous-organic medium under heating and vigorous stirring, characterized in that the higher saturated carboxylic acids or their mixtures are reacted with metal hydroxides or oxides of groups II, IV of the Periodic system elements (Ca, Ba, Zn, Cd, Mg, Pb) or their mixtures in the ratio of the starting reagents acid: base (oxide) = 2: 1 mol / mol and the process is carried out at the solid-liquid interface in two stages in the presence of alcohol-dispersant in an amount of 0.1-1.0 wt.% (relative to the mass of saturated carboxylic acids) with a two-stage temperature increase in the reaction zone, at the first stage, the reaction mixture is heated to a temperature not exceeding 50 ° C and can not stand more than 30 minutes, at the second stage the reaction mixture is heated to a temperature of no higher than 70 ° C and can withstand no more than 180 minutes. 2. The production method according to claim 1, characterized in that the dispersant used is a range of alcohols (methanol, ethanol, propanol, isoprapanol, butanol), polyhydric alcohols (ethylene glycol, glycerol, diethylene glycol). 3. The method according to claim 1, characterized in that as the saturated carboxylic acids use stearic, palmitic, myristic, margaric, lauric acids, synthetic fatty acids (FFA) fractions C ₁₆ -C ₂₂ .
