摘要
本文报导应用亚磷酸、甲醛和二乙撑三腕合成二乙撑三胺五甲撑基膦酸的方法并研究了它在硬水中对金属缓蚀，阻垢的性能，试验表明，二乙撑三胺五甲撑基膦酸对２０＃碳钢具有优良的缓蚀性能，并能与苯并三氮唑复配，对水中钙、镁离子具有较好的抑制沉淀作用。
In this paper, we described a method about synthesis of diethylenetriamine pentamethylene phosphonic acid by using phosphorous acid, formaldehyde, diethylenetriamine and investigated its character for inhibiting corrosion and stale to metal inhard water. Test shown DETAPP possessed a cxcellent capacity inhibiting corrosion tosted and can prevent deposit for Ca and Mg in hard water.
