胺类化合物是广为使用的酸性介质缓蚀剂。丙炔醇在酸性介质中还具有抑制氢渗透的能力。结合这两类化合物的有效缓蚀基团,有可能得到在高温浓酸中使用的高效缓蚀剂。我们曾以这两类化合物为原料,合成了二丙炔氧甲基烷基胺系列化合物本工作则采用动电位扫描和交流阻抗方法研究它们的电化学行为。
An investigation of electrochemical behavior of N, N-dipropynoxy methyl alkyl amine compounds was carried out by potentiodynamic and A. C. impedance measurements. It was found that the feature of anodic polarization curves of the compounds reflected desorption transition phenomena of the inhibitors. This type of inhibitors possesses high inhibition efficiency and is more effective in hydrochloric acid than in sulfuric acid. Inhibition action is a mixed type retarding both anodic and cathodic reactions. The inhibition mechanism is discussed.
