研究了制备磷钼酸的乙醚萃取法、王水法和三氧化铝十磷酸法。设计了制备磷钼酸的一种新方法——乙醇溶解法。磷钼酸是一种重要的化学试剂。除特别标明外,一般指化合物 H_3PO_4·12M_0O_3·xH_2O,(X 从3—30)。易溶于水、醇及乙醚。易还原成钼兰。我们重复了文献上记载的制备磷钼酸的“乙醚萃取法”和“王水法”,并且调查了生产上采用的“M_0O_3+H_3PO_4法”。在总结这些方法的基础上,提出制备磷钼酸的乙醇溶解法。
The preparation of phosphomolybdic acid ether extraction method, aqua regia and alumina triphosphoric acid method. A new method of preparing phosphomolybdic acid was designed-ethanol dissolution method. Phosphomolybdic acid is an important chemical reagent. Unless otherwise specified, generally refers to the compound H_3PO_4 · 12M_0O_3 · xH_2O, (X from 3-30). Soluble in water, alcohol and ether. Easy to restore to molybdenum. We repeated the literature on the preparation of phosphomolybdic acid “ether extraction method” and “aqua regia law” and investigated the production of “M_0O_3 + H_3PO_4 method.” On the basis of summarizing these methods, an ethanol dissolution method for preparing phosphomolybdic acid is proposed.
