含氯N-芳基-α-氨基苄基膦酸的合成及其对钢铁缓蚀性能的研究

SYNTHESIS OF N-ARYL-α-AMINO BENZYL PHOSPHORIC ACID CONTAINING CHLORINE AND EVALUATION OF THEIR CORROSION INHIBITING PROPERTIES FOR IRON AND STEEL

合成了四个新的含氯N 芳基 α 氨基苄基膦酸缓蚀剂 ,用元素分析、红外分析、1HNMR、31PNMR(核磁共振 )确定了它们的结构 ,并用静态腐蚀实验 (失重法 )研究其在不同浓度及 pH条件下对钢铁的缓蚀性能。

Four new N-aryl-α -amino benzyl phosphoric acids containing chlorine were synthesized as corrosion inhibitors. The structures of the acids were examined by using elemental analysis, IR, 1H NMR and 31P NMR spectrum techniques. The corrosion inhibiting properties for steels of the target compounds with different concentrations and pH values were investigated by using weight-loss tests.
