改进Pope等合成α_2-K_8P_2W_(17)VO_(62)的方法,在制备和分离出(NH_4)_8H_2P_2W_(15)V_3O_(62)和K_9P_2W_(16)V_2O_(62)的废液中分离出K_8P_2W_(17)VO_(62)。经元素分析,IR和NMR光谱证实为α_2-K_8P_2W_(17)VO_(62)。此法得到的产品纯度好,产量高,具有省时,省物,操作简单,适用于大批量生产等优点。
The method of synthesizing α_2-K_8P_2W_ (17) VO_ (62) by Pope et al was improved and K_8P_2W_ (6) was separated and purified from the waste liquid of preparation and separation of (NH_4) _8H_2P_2W_ (15) V_3O_ (62) and K_9P_2W_ (16) V_2O_ (62) 17) VO_ (62). After elemental analysis, IR and NMR spectra confirmed α_2-K_8P_2W_ (17) VO_ (62). The purity of the product obtained by this method is good, the yield is high, and the method has the advantages of saving time, saving matter, simple operation and being suitable for mass production.
