Corrosion Inhibition Performance of Imidazoline Amide for Carbon Steel in HCl/NH4Cl-H2O and H2S/NH4HS-H2O Solution
摘 要
采用失重法、电化学测试法,并结合扫描电镜和原子力显微镜观察,研究了在50 ℃条件下,N-(2-辛基-2咪唑啉)三亚乙基四酰胺(咪唑啉酰胺)分别在HCl/NH4Cl-H2O和H2S/NH4HS-H2O体系中对碳钢的缓蚀性能。结果表明: N-(2-辛基-2咪唑啉)三亚乙基四酰胺加量为15 mg/L时,缓蚀率接近90%,缓蚀效果明显;该缓蚀剂为抑制阳极型缓蚀剂,溶液中加入缓蚀剂后,碳钢试样形成较长的钝化区间,交流阻抗半径大,腐蚀电流明显减小。形貌观察显示N-(2-辛基-2咪唑啉)三亚乙基四酰胺能够在碳钢表面形成致密的保护膜。
Abstract
Weight-loss method, electrochemical methods, scanning electron microscopy and atomic force microscopy were used to study the corrosion inhibition performance of N-(2-octyl-2 imidazoline) triethylenetetramine amide for carbon steel in HCl/NH4Cl-H2O and H2S/NH4HS-H2O solution at 50 ℃. The results showed that the inhibition rate was close to 90% when 15 mg·L-1 corrosion inhibiter was added. The corrosion inhibitor is an anodic type corrosion inhibitor. After adding the inhibitor, long passivation range for the steel was formed, AC impedance radius became bigger, corrosion current decreased obviously. Microscopy result demonstrated that N-(2-octyl-2 imidazoline) triethylenetetramine amide could form a compact film on the surface of the carbon steel specimen to protect it from corrosion.
