摘　　要：采用方便的方法合成了一系列苯甲腈类化合物 ,并用静态腐蚀失重法测定了它们对碳钢在稀盐酸中腐蚀的缓蚀效率。实验结果表明 :苯甲腈类化合物具有较好的酸性缓蚀性能 ,特别是当苯环上氰基对位具有给电性基团时 。A series of substituted benzene carbonitriles were prepared by convenient method, and their inhibitive efficiency of carbon steel corrosion in dilute HCl solution was determined by method of corrosion weight loss. The result of experiment express: the kind of benzene carbonitrile compounds have good inhibitive ability against acid corrosion. Especially, when there is electron donating group on the paraposition of benzene ring, the aromatic nitrile has higher inhibitive efficiency in acid medium.
