Among chromite dichromate preparation processes with liquid-phase oxidation decomposition, the salting crystallization method for separation of chromate and caustic alkali is not only high energy consumption but also complex. In addition, there are other issues for the process, such as the chromate crystals produced usually entrain a certain amount of caustic alkali. To solve this problem, Hongbin Xu et al of Institute of Process Engineering proposed a leaching-distillation method for separation of chromate crystals and caustic alkali. It has very important significance to study systematically the effects of the solubility of sodium chromate, sodium hydroxide in methanol aqueous solution on the separation of chromate and caustic alkali with the methanol leaching method. |
