摘要
研究了合成的十二烷基二甲基（２－羟基）乙基氯化铵等含羟基季铵盐，对２０＃碳钢在１０％氨基磺酸水溶液中的缓蚀作用。结果表明：这一类季铵盐在酸性介质中有良好的缓蚀作用，随着烷基链的增长，缓蚀效率增加。
The corrosion inhibition for steel in the media of 10% sulfamic acid aqueous solution was studied. The reagents of corrosion inhbition are synthetic quaternary salts,such as decyl dimethyl(2 - hydroxy )ethyl ammonium chloride.The results showed that these quaternary ammonium salts are effective corrosion- inhibitor in acidic media and the effectiveness increases regularly wiith increasing of alkyl chain.
