Abstract
Imidazoline was synthesized on the basis of synthetic-, oxysynthetic- petroleum acids and polyethylenepolyamine in the ratio (1:1), at 230°C for 4 h and their organic and inorganic complexes with hydrochloric and acetic acids were obtained. Solutions of the obtained complexes in isopropanol were prepared in three concentrations (25; 150; 250 mg/l), their effect on sulfate-reducing bacteria vital activity was tested in 7-14 days at 30-32°C. It was determined that imidazoline had 64.5%, imidazoline complex with hydrochloric acid - 87.5%, imidazoline complex with acetic acid - 91% of bacteria-destroying inhibitor-bactericidal effect at a concentration of 250 mg/l. Keywords: microbiological corrosion, imidazoline, synthetic petroleum acid, polyethylenepolyamine, sulfate-reducing bacteria.
