本工作从Wilson参数的物理意义出发,用纯组分液体的摩尔内能,导得了一个单参数Wilson方程,用来关联并进行从等温或等压汽液平衡数据推算其他温度或压力下的汽液平衡数据的计算。结果表明,对已进行计算的三十多个体系,包括烃、醇、醚、醛、酮、酯及卤代物等组成的各类体系,关联和推算都获得了较为满意的结果。 Starting from the physical meaning of the Wilson parameter and using the molar internal energy of the pure component liquid, this work leads to a one-parameter Wilson equation that is used to correlate and derive vapor at other temperatures or pressures from isothermal or isobaric vapor-liquid equilibrium data Liquid equilibrium data calculation. The results show that the correlation and the estimation of the three systems, which have been calculated, including the systems of hydrocarbons, alcohols, ethers, aldehydes, ketones, esters and halides, have achieved satisfactory results.
