【Abstract】 The adsorption and the inhibiting effect of polyamines in naphthenic acid/A3 steel system are studied through weight-loss and electrochemical method.The results show that polyamine has the capability to inhibit the corrosion of naphthenic acid.The coverage lowers down as temperature rise.The adsorption heat ΔH=-51 kJ/mol<0.According to that,the contribution of polyamines turning naphthenic acid into non-corrosion substances is proposed.更多还原
