摘要
New branched conjugated derivatives with two benzotriazole groups as well as a linear analog containing one benzotriazole segment used as corrosion inhibitors for copper in 3.5 wt% sodium chloride solution containing 90 vol% water and 10 vol% ethanol solvents at 298 K were synthesized. It is shown that the corrosion of copper is inhibited more efficiently by the branched inhibitors. The adsorption mechanism on copper surface was analyzed by Langmuir isotherm and various spectral characterizations, and the results suggest a primary chemisorption adsorption on copper surface. Molecular modeling was performed. Photo and thermal stabilities of the studied inhibitors were investigated.
