2-氨基苯并咪唑及其衍生物在0.5 mol/L硫酸中对碳钢的缓蚀性能
Corrosion Inhibition of 2-Aminobenzimidazole and Its Derivatives for Carbon Steel in 0.5 mol/L H2SO4
摘 要
采用静态失重法和电化学技术等研究了2-氨基苯并咪唑（ABT）及2-正己氨基-4-（3'-N，N-二甲氨基-丙基）氨基-6-（苯并咪唑-2-基）氨基-1，3，5-均三嗪（BACT）在0.5 mol/L硫酸溶液中对45号碳钢的缓蚀性能。结果表明：在0.5 mol/L硫酸溶液中，BACT比ABT具有更好的缓蚀作用。当缓蚀剂浓度为0.20 mmol/L时，BACT对碳钢的缓蚀率可达86.07%，而ABT对碳钢的缓蚀率仅为42.13%。通过表面张力仪研究了BACT和ABT在0.5 mol/L硫酸溶液中的表面活性。通过量子化学计算和分子动力学模拟方法研究了缓蚀剂在金属Fe界面上的吸附作用。结果表明：BACT的吸附作用明显高于ABT的；BACT分子结构中亲水基、疏水基和三嗪环的引入提高了其在碳钢表面的吸附成膜作用，从而提高了缓蚀剂的缓蚀性能。

Abstract
Weight loss method and electrochemical technology were employed to evaluate the inhibition efficiency of 2-aminobenzimidazole (ABT) and 2-(n-hexylamino)-4-(3'-N,N-dimethylamino-propyl) amino-6-(benzimidazole-2-yl) amino-1,3,5-s-triazine (BACT) for carbon steel in 0.5 mol/L H2SO4 solution. The results showed that BACT had higher adsorption property than ABT in 0.5 mol/L H2SO4 solution. The inhibition efficiency could reach 86.07% with 0.20mmol/L BACT, while 42.13% with ABT of the same concentration. Surface activities of BACT and ABT in 0.5 mol/L H2SO4 solution were studied by surface tension meter. The adsorption ability for BACT and ABT on the surface of carbon steel was studied by quantum chemical calculations and molecular dynamics simulations. The results showed that the adsorption ability for BACT on Fe (100) surface in aqueous solution was much higher than that for ABT. Considering above results, the high inhibition efficiency of BACT should attributed to the enhancement of its adsorption property due to the surface activity of BACT and the addition of triazine group.
