| 摘 要： | 实验测定了不同温度下,间二甲苯-水二元体系和间二甲苯-磷酸-水三元体系的液-液相平衡数据。研究了磷酸中的杂质Fe~(3+)、Al~(3+)和Mg~(2+)对间二甲苯-磷酸-水三元体系相平衡的影响,以及杂质在两相中的分配情况。研究结果对共沸精馏浓缩磷酸提供了必要的理论依据和基础数据。

| Abstract: | The Liquid-Liquid equilibrium data for m-xylene-water and m-xylene-phosphoric acid-water systems were measured, the effects of impurities such as Fe~(3+), Al~(3+) and Mg~(2+) containing in the phosphoric acid on LLE data and the distribultion of these impurities in phases were investigated. The LLE data obtained can be used in azeotropic distillation calculation for concentration of phosphoric acid. |
