采用稳态电化学和重量分析方法研究了2-(烷基(CnH2n+1)二甲基铵)链烷醇溴化物系列表面活性剂对铁在酰氯介质中的缓蚀作用。获得的结果表明这些化合物是非常好的阴极抑制剂并且作用于阴极氢反应放出而不改变其机理。在其临界胶束浓度附近观察到高抑制效率，并且抑制效率随着链长中碳原子的数量而增加。
The inhibitor effect of some surfactants in the series of 2-(alkyl(CnH2n+1)dimethylammonio)alkanol bromides on the corrosion of iron in acid chloride medium have been investigated by steady-state electrochemical and gravimetric methods. Results obtained show that these compounds are very good cathodic inhibitors and act on the cathodic hydrogen reaction evolution without modifying its mechanism. High inhibition efficiencies are observed around their critical micellar concentrations and the inhibition efficiency increases with the number of carbon atoms in the chain length.
