三水磷酸氢镁合成小试研究

Study on the Synthesis of Magnesium Hydrogen Phosphate Trihydrate

以浓厚卤处理后得到的晶体氯化镁为原料,和磷酸氢二钠溶液反应合成三水磷酸氢镁,考察了反应温度、溶液的pH值、物料比、反应时间对产品纯度的影响。

In this article,Magnesium hydrogen phosphate trihydrate was prepared by reaction of the crystal magnesium chloride obtained from strong brine treatment with the disodium hydrogen phosphate solution.Effects of the reaction temperature,pH value of the solution,material ratio and reaction time on product purity were investigated.
