【摘要】 文中提出了一种新型的制备HEDP的方法 ,即利用缓蚀剂与阻垢剂联合法制备HEDP。该方法解决了常规方法中存在的污染环境、浪费原料、产品质量较低的问题。实验给出当反应温度为 35～ 40℃ ,原料配比为 1 :0 9,保温时间为 3h ,保温温度为 1 2 0℃时 ,产率较高 ,为最佳反应条件。更多还原

【Abstract】 The preparation of HEDP with corrosion inhibitor and incrustation inhibitor unite method is studied and it fulfils the purpose by the routine method,such as environmental pollution,waste material and finished quality etc.The reaction conditions are determined by experiments,that is reacgione temperature:35～40℃,material proportion:1:0.9,soak:3?h,preserve heat temperature:120℃更多还原
