STUDY OF BACTERICIDE-INHIBITOR PROPERTIES AGAINST MICROBIOLOGICAL CORROSION PROCESS OF BROMIDE COMPLEX OF IMIDAZOLINE BASED ON NORBORNENE CARBOXYLIC ACID AND DIETHYLENETRIAMINE

The article investigates the bactericidal-inhibitory properties against microbiological corrosion of imidazoline bromide complex synthesized based on norbornene carboxylic acid and diethylenetriamine. For this purpose, in the first stage, imidazoline was synthesized from the interaction of norbornene carboxylic acid with diethylenetriamine. In the second step, an inorganic anionic complex was obtained from the reaction of imidazoline with allyl bromide. The structure of the obtained compound was confirmed by the IR spectroscopic method. The synthesized complex was tested as a bactericide-inhibitor. Solutions of the complex in two concentrations (25 and 50 mg/l) were prepared, and the effect on the life activity of sulfatereducing bacteria was checked at a temperature range of 30-32˚C for 7-14 days. Based on the test results, it was determined that the obtained complex has a bactericidal effect of 97.3% at a concentration of 25 mg/l and 100% at a concentration of 50 mg/l. It was determined that the obtained complex completely stopped the life activity of SRB. The synthesized complex was compared with industrial inhibitors and it was determined that the inhibitor of Dodigen-414 (Germany) biocidal effect is 45% at a concentration of 25 mg/l, 60% at a concentration of 50 mg/l, and 85% at a concentration of 100 mg/l. The inhibitor of Sever-1 (Russia) biocide effect is 20% at a concentration of 25 mg/l, 35% at a concentration of 50 mg/l, and 60% at a concentration of 100 mg/l. It was determined that the synthesized imidazoline bromide complex completely stopped the life activity of SRB with a high bactericidal effect at all three concentrations.
