<正> 关于腈类化合物对酸性溶液中碳钢的缓蚀作用国外有一些报导。我们曾对苯乙腈类化合物的分子结构与缓蚀性能的关系作过一些探讨。为了进一步探索化合物的分子结构与其缓蚀作用间的关系。我们研究了氰基与苯环直接相连的苯甲腈类化合物的缓蚀性能,并对协同效应作了初步的探讨。
The corrosion-inhibiting abilities of a series of ringsubstituted benzonitriles were investigated. As in the case of benzene-acetonitriles, chemisorption is probably the mechanism of the corrosion-inhibiting effects.Introducing electtondonating groups in the para-position increases the corrosion-inhibiting ability, while introducing of electron-withdrown groups in the para-position decreases the corrosion inhibiting ability, when a substituent is positioned in o, m or P positions,both elec tronic and steric effects of the substituent affect the corrosioninhibiting ability. Besides, synergistic effect was observed when P-chlorobenzonitrile was used together with anionic or cationic dispersion agents.
