摘　　要：用五参数NRTL方程 ,对辛烷 -水二元部分互溶全系的汽 -液相平衡数据和液-液相平衡数据进行关联 ,并用液 -液相平衡数据优化所得的参数 ,预测汽液相平衡 。The vapor-liquid and liquid-liquid phase Equilibrium data for the partially miscible system of octane-water have been correlated by NRTL Equation with five parameters.The vapor-liquid Equilibrium dat of octane-water was predicted by parameters obtained from liquid-liquid Equilibrium data of the system.The accuracy of the calculation is high enough for the processes design.

关 键 词：NRTL方程 相平衡 关联 预测
