辛烷-磷酸-水三元体系液液相平衡

Liquid-liquid phase equilibrium for the ternary system of octane-phosphoric acid-water

实验测定了不同温度下辛烷 水二元体系和辛烷 磷酸 水三元体系的液 液相平衡数据。用 5参数NRTL方程对液 液相平衡数据进行了关联 ,精度满足工程设计的要求。

The Liquid Liquid equilibrium data of octane water and octane phosphoric acid water system were measured. The phase equilibrium data have been correlated by NRTL equation with five parameters and the accuracy of the calculation is high enough for the design processes. the LLE data about octane water and octane phosphoric acid water system can be used to the azeotropic distillation calculation for concentration of phosphoric acis.
