INHIBITION OF COPPER IN AGGRESSIVE ENVIRONMENTS BY QUINOLINE.

Experimental data lead to the following conclusions: Quinoline is an effective cathodic inhibitor of corrosion of copper in H//2SO//4, NaCl, sea water, and acid chloride solutions. The degree of polarization increases with an increase in the concentration of quinoline. Quinoline is not very effective as an anodic inhibitor. The physical adsorption of quinoline on copper results in blockage of active sites for h. e. r. The presence of chloride ions does not impede the adsorption of quinoline on the copper surface. Synergistic interaction is not strong enough to cause chemisorption.
