摘要：

A variety of new dibenzotriazoles bearing alkylene linker as well as corresponding monobenzotriazoles using as corrosion inhibitors for copper in 3.5 wt% sodium chloride solution at 298 K were prepared. The corrosion inhibition efficiencies of these benzotriazoles were determined by electrochemical methods and weight loss experiments. Furthermore, scanning electron microscopy was utilized to compare corrosion inhibition effect. The results showed that corrosion of copper in NaCl solution could be inhibited more efficiently by dibenzotriazole derivatives comparing to monobenzotriazole ones. The inhibition mechanism of dibenzotriazoles on copper was analyzed by Langmuir isotherm, Fourier transform infrared spectra and X-ray photoelectron spectroscopy. (C) 2016 Elsevier Ltd.
