新型苯并三氮唑离子液体的合成及其对铜缓蚀性能的研究

The Study on Synthesis of New Benzotriazole Ionic Liquids and Its Corrosion Inhibition for Brass

用挂片失重法、电化学极化曲线和交流阻抗的方法,研究了合成的两种离子液体与BTA在p H=3的H2SO4溶液中的协同作用,并与BTA在p H=3的H2SO4溶液中对黄铜的缓蚀性能加以比较,结果表明,这两种离子液体与BTA复配后显示了比BTA更好的缓蚀性能。

The synergistic effect of two kinds of synthetic ionic liquid with BTA in the sulfuric acid solution（p H=3） was studied with weight loss, electrochemical polarization curves and alternating current impedance methods. And their corrosion inhibition for brass in sulfuric acid solution（p H=3）was compared with that of BTA. The results indicated that the two kinds of ionic liquid compounded with BTA in the sulfuric acid solution（p H=3）would exhibit a better corrosion inhibition for brass than the BTA did.
