摘要
以乙二胺、三氯化磷、甲醛为原料,在乙二醇作用下,合成了乙二胺四甲撑基膦酸(EDTMP),研究了EDTMP对次氯酸钠溶液的有效稳定作用,结果表明,以乙二醇作介质合成EDTMP具有产率高、纯度高的优点,对次氯酸钠溶液的稳定效果优于其它稳定剂。
From the paper described a method to synthesis 1,2-ethanediylbis[nitrlobis(methylene)] tetraphosphonic acid EDTMP by using phosphorus trichloride, formaldehyde and ethylenediamine in glycol. Besides which, studed stability of EDTMP for sodium hypochlorite Solution. Their result has been shown both are higher for yield and purity of EDTMP, under the action of glycol, when applied of stabiliting Sodium hypochlorite, its effect is better than other stabilizer.
