FIELD: organic chemistry. SUBSTANCE: invention relates to benzimidazole derivatives, in part, 2-(quinolyl-4')-benzimidazole where compounds HClO4,(CH3)2SO4,CH3-C6H4SO3CH3,CH3I,C2H5I. were used as salt-forming agents. Synthesis is carried out from 2-(quinolyl-2')-benzimidazole and the corresponding salt-forming agent. Yield, %; m. p., C; empirical formula: a) 72; 300-301; H2S-; b) 80; 235; C46H11N3•2HClO4•H2O; c) 76; 215; C20H25N3S2O9;; d) 63; 242-243; C32H31N3S2O6•H2O;; e) 65; 232-233; C19H19I2N3•H2O;. Protection degree of steel (sort St.3) at 30-80 C with new compounds is 80-99.9% (60.4% for the known inhibitor C22H25I2N3•H2O.). These salts exhibit capability to inhibit steel corrosion in acid and ЧМ-containing media that can be used for anticorrosion protection of equipment in chemical and oil production industry. EFFECT: enhanced activity of synthesized compounds. 4 tbl
