摘要
以二甲亚砜为溶剂 ,用芳醛与芳胺、亚磷酸一步合成了 9个未见文献报道的 N-芳基 -α-氨基苄基膦酸 ,并研究了它们与锌盐复配在 p H=8的碱性介质中对 A3钢的缓蚀作用 .试验表明 ,以二甲亚砜为溶剂来合成膦酸是一种较为理想的合成手段 ;N-芳基
Nine N- aryl- α- amino benzylene phosphonic acids are prepared directly from aromatic aldehyde with aromatic amine and phosphorus acid using dimethyl sulfoxide as medium.Their inhibiting corrosions with zinc salt combined are also tested on A3steel in water solution of p H=8.The resultshows the method of synthesis of phosphonic acid is more effective,and N- aryl- a- amino benzylene phosphonic acids have better concerted action with zinc salt combined.
