通过失重和电化学方法研究了多胺化合物在环烷酸腐蚀体系 的作用.结果表明：多胺具有抑制环烷酸腐蚀的能力，随着温度的升高覆盖度减低，吸附热 为ΔH＝-51kJ/mol<0,据此,推测了多胺将环烷酸转化为非腐蚀性物质在抑制环烷酸腐蚀 中的贡献.
The adsorption and the inhibiting effect of polyami nes in naphthenic acid/A3 steel system are studied through weight-loss and elect rochemical method.The results show that polyamine has the capability to inhibit the corrosion of naphthenic acid.The coverage lowers down as temperature rise.Th e adsorption heat ΔH=-51 kJ/mol<0.According to that,the contribution of polyami nes turning naphthenic acid into non-corrosion substances is proposed.
