【摘要】 合成了月桂酰基硫脲缓蚀剂,并通过传统的静态失重法结合现代的电化学测试方法初步考察了其抗CO2腐蚀的缓蚀性能。结果表明,该缓蚀剂在CO2腐蚀介质中,当投加量为0.10 g/L时,缓蚀剂的缓蚀效率达91.49%。通过极化曲线分析可知,该缓蚀剂一种抑制阳极过程为主的阳极型缓蚀剂。电化学阻抗谱测试表明,该缓蚀剂通过负催化效应而起到缓蚀效果。更多还原

【Abstract】 The lauric acyl thiourea derivatives are synthesized,and its inhibition performance for CO2 corrosion is studied by traditional weight-loss method and modern electrochemical method.The results indicate that the inhibition efficiency can reach to 91.49% for the CO2 corrosion when its concentration is 0.10 g/L.The polarization curves analysis reveals that the inhibitor is an anodic type,and the electrochemical impedance spectroscopy(EIS) shows that the inhibitor is due to the negative catalytic mechanism.更多还原
