Popis: | A series of 3-(N-arylamino)-5-amino-1Н-1,2,4-triazoles were prepared by the reaction of S,S-dimethyl cyanodithioimidocarbamate with appropriate anilines. The inhibiting effect of the products on the corrosion of copper of M1 grade in acidic and neutral chloride-containing media was studied using electrochemical and accelerated electroless methods. The maximal degree of protection ensured by commercially available 3,5-diamino-1H-1,2,4-triazole and the synthesized 3-phenylamino, 3-(4-methylphenylamino), 3-(4-chlorophenylamino), and 3-(3-chlorophenylamino) derivatives of 5-amino-1Н-1,2,4-triazole reaches 70–87%. In acid solutions, the synthesized compounds show higher performance than the 3,5-diamino derivative, ensuring up to 92–96% protection. Similar results were obtained in experiments in a salt fog chamber. |
