关于有机膦、胂合钨、钼聚多酸盐的制备,文献已有若干记载。这类化合物具有“柄状”的结构。所用钨、钼的反应物是Na_2WO_4、Na_2MoO_4(有时用MoO_3或Na_6Mo_7O_(24)),与有机膦酸或胂酸在增加或减低酸度时反应而得到这些柄状化合物。实验表明,从聚多酸盐逐步提高pH值的途径对有机胂柄状物产量有利。由于我们在偏钨酸盐方面已有简捷的制备法,因而本报告中所制得的有机胂合钨化合物,都以此为出
On the organic phosphine, arsenic tungsten, molybdenum polyacid salt preparation, the literature has a number of records. Such compounds have a “handle-like” structure. The tungsten and molybdenum reactants are Na 2 WO 4, Na 2 MoO 4 (sometimes with MoO 3 or Na 6 Mo 7 O 4 (24)) and react with organic phosphonic acid or arsonic acid to increase or decrease the acidity to give these stalk compounds. Experiments show that the gradual increase of the pH value from the polyacid salt is beneficial to the yield of the organic arsine handle. Since we have a simple method for the preparation of metatungstate, so the report prepared in the organic arsenic tungsten compounds, are used as a
