The solubility in the water-salt quaternary reciprocal system Na2Cr2O7 + 2NH4Cl ⇆ (NH4)2Cr2O7 + 2NaCl-H2O has been investigated for the first time at 25, 50, and 75°C. Using a formal analytical model, the boundaries of the phase
fields have been determined, and the univariant lines and invariant points have been calculated. The experimental data have
been used to calculate the temperature and concentration parameters of the circular isohydric process of potassium dichromate
preparation with the participation of ammonium salts as intermediates. 相似文献
