一种苯胺类席夫碱对N80钢在盐酸介质中的缓蚀性能
Inhibition Performance of an Aniline Schiff Base Inhibitor for N80 Steel in HCl Solution
摘 要
合成了一种席夫碱:4-氯-N-[(吡啶-4基)-亚甲基]苯胺(CNP),并采用失重法、电化学阻抗谱和动电位极化曲线等,研究了CNP对N80钢在1 mol/L HCl溶液中的缓蚀性能.结果表明,在1 mol/L HCl溶液中,当缓蚀剂 摩尔浓度为1.0 mmol/L时,缓蚀率达到86.17%.其在N80钢表面吸附满足Langmuir吸附等温式,是一种混合型缓蚀剂.

Abstract
A Schiff base named 4-chloro-N-(pyridine-4-ylmethylene)aniline (CNP) was prepared.Weight loss method,electrochemical impedance spectroscopy ,potentiodynamic polarization curves,scanning electron microscopy and other methods were used to study the inhibition performance of CNP Schiff base for N80 steel in 1 mol/L hydrochloric acid solution.The results showed that the CNP had excellent inhibiting effect.When the concentration was 1.0 mmol/L,the inhibition efficiency reached 86.17% in 1 mol/L hydrochloric acid solution.The CNP is a mixed type inhibitor and the adsorption of CNP on N80 steel surface obeys the Langmuir adsorption isotherm.
