本文报导了用电解酸化法制备二种不同系列的锰钒杂多化合物。(NH_4)_(4、5)H_(0.5)Mn~ⅣV_(11)O_(32)·12H_2O和(NH_4)_5HMn_3~ⅣV_(12)O_(39)·15H_2O。制备时不用外加酸和氧化剂,反应条件容易控制。文献未有给出上述第二个化合物的直接合成方法,是从重结晶第一个化合物的母液析出的晶体中机械分离得到,产率很低。本文给出了直接合成的方法。
This paper reports the preparation of two different series of manganese vanadium heteropoly compounds by electrolytic acidification. (NH_4) _ (4,5) H_ (0.5) Mn ~ ⅣV_ (11) O_ (32) · 12H_2O and (NH_4) _5HMn_3 ~ ⅣV_ (12) O_ (39) · 15H_2O. Preparation without the addition of acid and oxidant, the reaction conditions easy to control. No direct synthesis of the above second compound is given in the literature by mechanical separation from the crystals precipitated from the mother liquor of the first recrystallized compound with a very low yield. This article gives a direct synthesis method.
