CHEMISTRY AND CHEMICAL ENGINEERING

Abstract

The aim of this work was to obtain corrosion inhibitors. It has been established that heterocyclic compounds, including pyridine and its derivatives, are more frequently used as the active component in the combination of modern inhibitors of carrosion The catalytic reaction of obtaining pyridine and its derivatives by passing a mixture of acetaldehyde and formalin with ammonia was studied. By modifying the mixture of the obtained pyridine bases with urotropine, acrylic emulsion, thiourea, copper salts, etc., compositions are obtained that can serve as inhibitors of hydrochloric acid treatment.
