摘要

摘要合成了一种新型吡啶衍生物,并用重量法研究了其在1M盐酸环境中对软钢的缓蚀作用。结果表明,吡啶衍生物的缓蚀性能随着缓蚀剂浓度的增加而提高。在303,吡啶衍生物4-羟基-3-(吡啶-2-基氨基甲基)甲苯在抑制剂浓度为0.005M时的抑制效率达到96.2%。抑制机制涉及通过Langmuir吸附等温线在软钢表面由抑制剂分子形成保护层。通过CHN分析证实,4-羟基-3-(吡啶-2-基氨基甲基)甲苯结构中存在氮和氧原子,揭示了抑制剂分子在软钢表面的吸附。

Corrosion inhibition of mild steel using novel pyridine derivative in 1 M hydrochloric acid
Abstract A novel pyridine derivative was synthesized, and its corrosion inhibition effects on mild steel in a 1M hydrochloric acid environment were investigated by gravimetric techniques, The results demonstrated that the inhibitive performance increased with the increasing of inhibitor concentration. At 303, the inhibition efficiency of pyridine derivative 4-hydroxy-3-(pyridin-2-ylaminomethyl)toluene accomplished 96.2% at the inhibitor concentration of 0.005 M. The mechanism of inhibition implicated the forming of a protective layer from inhibitor molecules on the surface of mild steel by a Langmuir adsorption isotherm. The presence of nitrogen and oxygen atoms in the structure of 4-hydroxy-3-(pyridin-2-ylaminomethyl)toluene confirmed by CHN-analysis revealed the adsorption of inhibitor molecules on the surface of mild steel surface.
