| 目的 对 N,N'-二(二苯基膦基)-1-苯乙胺(NPM)的合成、结构表征及其在盐酸介质中对碳钢的缓蚀性能进行研究。 方法 用红外光谱、元素分析和熔点测试等方法对 NPM 的结构进行表征,采用静态失重法、动电位极化曲线法和电化学阻抗法研究 NPM 在盐酸介质中对碳钢的缓蚀作用,研究腐蚀体系温度、HCl 浓度、NPM 浓度和腐蚀体系静置时间对 NPM 缓蚀率的影响,探讨 NPM 在碳钢表面上的吸附机理。 结果 动电位极化曲线法研究结果表明 NPM 是一种混合型缓蚀剂。 NPM 的缓蚀率随 NPM 浓度的增加而增大,当 NPM 的质量浓度为 140 mg/ L 时,NPM 在 25 ℃ 的 1. 0 mol/ L HCl 溶液中的缓蚀率达到94. 71% ;NPM 的缓蚀率随腐蚀体系温度的升高而降低,随 HCl 浓度的增大而减小,但随腐蚀体系静置时间的延长缓蚀率逐渐增大。 NPM 在碳钢表面的吸附符合 Langmuir 吸附等温方程式,属于自发进行的物理和化学吸附。 结论 所合成的化合物 NPM 是一种高效的混合型有机缓蚀剂。 |

| Objective To study the synthesis, structure characterization and inhibition performance of N,N'-bis(di-phenylphos-phino)-1-phenylethylamine (NPM) on carbon steel in hydrochloric acid solution. Methods The structure of synthesized NPM was characterized by means of infrared spectroscopy, elemental analysis and melting point test. And the inhibitive efficiency of NPM on carbon steel in hydrochloric acid solution was investigated using the static weight loss method, potentiodynamic polarization curve and electrochemical impedance. The influences of the corrosion system temperature, NPM concentration, hydrochloric acid concentration and standing time of the corrosion system on the corrosion inhibition efficiency of NPM on carbon steel were studied, and the adsorption mechanism of NPM on carbon steel surface was also discussed. Results The potentiodynamic polarization curves indicated that NMP acted as a mixed-type inhibitor. The results for influencing factors of the inhibitive efficiency of NPM showed that the inhibitive efficiency of NPM increased with increasing NPM concentration, and the inhibition efficiency reached up to 94. 71% at 140 mg / L NPM in 1. 0 mol / L hydrochloric acid solution at 25 ℃ . It decreased gradually with the increase of the corrosion system temperature and the hydrochloric acid concentration, while increased with increasing standing time of the corrosion system. The adsorption process of NPM on carbon steel surface obeyed Langmuir isotherm and belonged to spontaneous physical and chemical adsorption. Conclusion The synthesized organic compound NPM was a highly efficient mixed-type corrosion inhibitor. |
