摘要 目前有关布朗斯特酸(Brnsted)离子液体腐蚀的报道较少,且含水量对离子液体的酸性影响较大。利用电化学方法研究了Q235B低碳钢在不同含水量的布朗斯特酸离子液体[(CH2)4SO3HMIm][HSO4]中的腐蚀行为,采用扫描电子显微镜(SEM)、能谱仪(EDS)、核磁共振仪分析了Q235B钢电极电化学试验后的表面形貌及元素组成,讨论了其电化学作用机理。结果表明:随着离子液体含水量的增加,碳钢耐腐蚀性降低;此Brnsted酸离子液体同时具有强酸性和低腐蚀性,易循环使用,有望取代具有强腐蚀性的传统酸,成为工业用酸性催化剂。 The corrosion behavior of Q235 B mild steel in Brnsted acidic ionic liquid[(CH_2)_4 SO_3 HMIm][HSO_4]with different contents of water was studied with electrochemical method.The surface morphology and elemental composition of the mild steel after electrochemical tests were analyzed by scanning electron microscopy,energy dispersive spectrometry,and nuclear magnetic resonance spectroscopy;and its electrochemical action mechanism was discussed.Results showed that the corrosion resistance of the mild steel decreased with the increase of water content in[(CH_2)_4SO_3HMIm][HSO_4]ionic liquid.The Brnsted acidic ionic liquid exhibited strong acidity and low corrosiveness and could be readily recycled,showing promising potential as a kind of acidic catalyst in industry to replace conventional acid.
