摘要
用电化学极化电阻法研究了某些有机合氮化合物抑制铁腐蚀的结构效应．根据缓蚀剂分子中取代基的类型、数目和空间取向，以及配位体Ｎ上电子与铁空ｄ轨道形成配位键的强弱，解释了有机合氮化合物的结构对其缓蚀效率的影响．
The structural effects of some nitrogen-containing organic compounds on corrosioninhibition of iron in acidic media we-re studied by electrochemical polarization resistancemeasurements. The influence of chemical structure of inhibitors on the corrosion inhibition action was interpreted by the types.numbers and space position of the substituentand the intensity of coordinate covalent bond formed between electrons on nitrogen atomand the outer-shell unoccupied d-electron orbits of iron.
