摘要
采用改进的Ellis平衡釜测定了蒎烷α蒎烯、α蒎烯长叶烯、蒎烷长叶烯三个二元及蒎烷α蒎烯长叶烯三元常压汽液平衡数据,实验数据经Herrington规则检验,表明符合热力学一致性,并分别用Wilson和NRTL模型对三个二元体系汽液平衡数据进行了关联,得到了相应的模型参数,同时用二元Wilson参数对所测的三元数据进行了推算,计算结果与实验值的平均偏差为0.0027.
The vapor liquid equilibrium data for three binary systems of pinane α pinene, α pinene longifolene and pinane longifolene and ternary system of pinane α pinene longifolene were determined at 0.101 3 MPa by the modified Ellis still. The thermodynamic consistency test indicated that the experimental data of three binary systems were reliable. The data were correlated by Wilson and NRTL equation , and the energy parameters have been attained. The calculated values were in good agreement with measured values. Meanwhile, The vapor liquid equilibrium data for ternary system of pinane α pinene longifolene have been estimated by Wilson equation, and the average deviation was 0.002 7.
