Action of sulphur containing inhibitors on the corrosion of 63/37 brass in trichloroacetic acidTrichloroacetic acid is highly corrosive to brass. Sodium thioglycolate, sodium diethyl dithio carbamate and carbon disulphide have been studied as corrosion inhibitors for brass (63/37) in trichloroacetic acid. The inhibitive power of sulphur-containing organic compounds is due to chelate formation, the chelate adhering strongly to the metal surface. The efficiencies of above stated inhibitors were found in the following order: \documentclass{article}\pagestyle{empty}\begin{document}$$ {\rm Na - DDC}\,{\rm 〉 }\,{\rm CH}_{\rm 2} {\rm (SH)COONa}\,{\rm 〉 }\,{\rm CS}_{\rm 2} $$\end{document}.
Notes:
Trichloressigsäure greift Messing stark an. Natriumthioglycolat, Natriumdiäthyldicarbamat und Schwefelkohlenstoff sind als Inhibitoren der Korrosion von Messing 63/37 in Trichloressigsäure untersucht worden. Die inhibierende Wirkung von schwefelhaltigen organischen Verbindungen beruht auf Chelatbildung, wobei das Chelat an der Metalloberfläche festhaftet. Die Wirkung der oben genannten Inhibitoren nimmt in der folgenden Reihe ab: \documentclass{article}\pagestyle{empty}\begin{document}$$ {\rm Na - DDC}\,{\rm 〉 }\,{\rm CH}_{\rm 2} {\rm (SH)COONa}\,{\rm 〉 }\,{\rm CS}_{\rm 2} $$\end{document}.
