FIELD: organic chemistry, chemical technology. SUBSTANCE: invention relates to a field of synthesis of adhesion materials, in part, technology of production of polyatomic carboxylic acids cobalt salts. Method of preparing polyatomic carboxylic acids cobalt salts involves interaction between mixture of polyatomic carboxylic acids sodium salt aqueous solutions and mineral acid cobalt salt followed by filtration and precipitate washing out, separation of primary precipitate and addition of precipitating agent taken among the group H2C2O4, Na2C2O4, Na2CO3, NaOH in the amount 110-120% of stoichiometry required amount to filtrate. The prepared combined precipitate is subjected for thermal treatment at temperature 180-220 C for 0.3-0.5 h. Method provides enhancement of economy of technological process at simultaneous stabilization of main indices of product prepared. Indicated compounds are used widely in tire, rubber-technical, paint and varnish and other branches of industry. EFFECT: improved method of preparing. 2 cl |
