INVESTIGATION OF Na, K, NH4 COMPLEXES OF SULFONIC ACIDS SYNTHESIZED ON THE BASIS OF LIGHT GAS OIL FRACTION AS BACTERICIDE

Abstract

The article is devoted to the preparation of Na, K, NH4 salts of alkylarylsulfonic and oligoalkylarylsulfonic acids synthesized on the basis of the light gas oil fraction obtained from the catalytic cracking process, the preparation of solutions of these salts in a mixture of ethyl alcohol+water and isopropyl alcohol+water, and the application of the synthesized samples as bactericide against sulfate-reducing bacteria. As a result of the research, it was determined that the bactericidal effect of the solutions of Na, K, NH4 salts of alkylarylsulfonic acid in a micture of ethyl alcohol+water at a concentration of 150 mg/l was 95%, 91.7%, 93%, respectively. While the solution of potassium salt prepared in a mixture of isopropyl alcohol+water at a concentration of 150 mg/l showed a lower result of 78.8% bactericidal effect, the solutions of sodium and ammonium salts taken at the same concentration in a mixture of isopropyl alcohol+water showed a bactericidal effect of 92% and 91%, respectively, and the number of bacteria minimized. The bactericidal effect of solutions of Na, K, NH4 salts of oligoalkylarylsulfonic acid in a mixture of ethyl alcohol+water at a concentration of 150 mg/l was 90.5%, 83%, 92.4%, accordingly. The solution of sodium salt prepared in a mixture of isopropyl alcohol+water showed a 94% bactericidal effect at a concentration of 150 mg/l and significantly reduced the number of bacteria. Also, it was determined that many samples of solutions of both alkylarylsulfonates and oligoalkylarylsulfonates prepared in a micture of alcohol+water at a relatively low concentration of 75 mg/l show an effect of more than 80%.
