间二甲苯－水二元体系液－液相平衡数据的测定和关联

Determination and Correlation of the Liquid-liquid Phase Equilibrium Data for the System of m-Xylen-Water

实验测定了间二甲苯－水二元体系在不同温度下的液－液相平衡数据．用ＮＲＴＬ方程、五参数ＮＲＴＬ方程及四参数ＶａｎＬａａｒ方程对液－相平衡数据进行了关联．其中五参数ＮＲＴＬ方程关联结果最佳．

The liquid-liquid equilibrium deta for the system of m-xylene-water at various temprature have been determined. The experimental date for the liquid-liquid equilibrium system have been related with NRTL equation,NRTL equation with five parameters and Van Laar equation with four parameters. of these equations, the NRTL equation with five parameters is more suitable for the system of m-xylene-water.
