α-蒎烯、β-蒎烯体系汽液平衡的研究

Study of vapor-liquid equilibrium on α-pinene and β-pinene

采用改进的Ellis平衡釜测定了α 蒎烯、β 蒎烯体系常压下的汽液平衡数据 ,经检验符合热力学一致性。以VanLaar模型、Wilson模型进行实验数据的关联 ,得到了相应的能量参数和配偶参数 ,结果表明 ,对α 蒎烯、β 蒎烯体系的汽液平衡计算 ,Wilson模型优于VanLaar模型。

The vapor liquid equilibrium data of α pinene and β pinene system were determined at 0 1013MPa by the modified Ellis still The thermodynamic consistency test indicated that the experimental data were reliable The data were correlated by Wilson and Van Laar equation ,got the energy parameters The calculated values were in good agreement with the measured values
