| 摘 要： | 将二氢噻唑衍生物与其它缓蚀剂进行了复配。用静态挂片失重法研究了它们的缓蚀效率。结果表明二氢噻唑和硫脲及表面活性剂的混合物对抑制CO2的气液两相的腐蚀有良好的效果。通过极化曲线和扫描电镜研究了该缓蚀剂的缓蚀机理。

| Abstract: | Dihydrothiazole was synthesized and mixed with normal corrosion inhibitors. The efficiency of the inhibitors was studied by static weight-loss method. Dihydrothiazole used together with thiourea and surfactant was a good corrosion inhibitor for controlling CO2 corrosion both in vapor and liquid phases. The mechanism was explained by polarization curves and SEM. |
