摘要
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。
Pure α_2-K_8P_2W_(17)VO_(62) was separated from waste liquid from which the (N H_4) _8H_2P_2W_(15)V_3O_(62) and K_9P_2W_(16)V_2O_(62) were prepared and separated by improving reported methods. By means of elementary analysis, IR, NMR spectra, it was determined that the formula of product is α_2-K_8P_2W_(17)-VO_(62) The product obtained by this method has good purity and high yields. This method has many advantages of saving time, using reagents sparingly, and operatin geasily, it is suitable for producing large quantities of products.
