摘要
应用苯甲醛及其衍生物与胺、亚磷酸一步合成出Ｎ－烃基－α－氨基苄基膦酸，并研究了它们对Ａ３钢在碱性介质中的缓蚀作用．试验表明，苯甲醛及其衍生物与胺、亚磷酸一步合成膦酸是可行的；Ｎ－烃基－α－氨基苄基膦酸在ｐＨ８或ｐＨ１２介质的水溶液中对Ａ３钢有较好的缓蚀作用．
N substituted α aminobenzylenephosphonic acids were synthesized by using benzaldehyde and its derivatives with amine, phosphorous acid.Their inhibiting corrosion were also tested on steel. Result showed that benzaldehyde and its derivatives can proceed one pot reaction with phosphrous acid and amine, and the phosphonic acid prossesses excellent corrosion resistance on A 3 steel in water solution of pH8 or pH12.
