Study on a new process of making hypophosphorous acid

次磷酸的新型生产方法的研究

Based on the literatures, in this paper, the preparation principle of organic substances of hypophosphorous acid are discussed.

本文在查阅文献资料的基础上，对几种典型的有机次膦酸的制备原理及应用进行了综述。

However, organic acids ( critric acid and ascorbic acid) are better than the hypophosphorous acid clearly.

然而，有机酸（抗坏血酸和柠檬酸）的效果明显好于次磷酸。

The best hydrolysis temperature of diazonium is 50~ 55 ℃, the highest yield can be obtained if 0.5% catalyst is added while reacting with hypophosphorous acid.

重氮盐最佳水解温度为50～55℃，与次磷酸反应的时候加入质量分数为0.5%的催化剂时，可得到最高收率。
