摘　　要：利用沸点仪测定β-苯乙醇与乙醇的汽液相平衡数据,同时实验测得的β-苯乙醇的饱和蒸汽压与温度,采用Lee-Kesler法估算不同温度下β-苯乙醇的饱和蒸气压,得到β-苯乙醇的Antoine方程,应用Wilson方程进行关联,获得相应的模型参数,为β-苯乙醇的分离提纯工艺提供了基础数据与理论依据。β - phenylethano and ethanol vapor - liquid equilibrium data were determined by using ebulliometer. At the same time, the experimental measured β - phenylethanol saturated vapor pressure and temperature. The saturated vapor pressures of β- phenylethanol at different temperatures were estimated by the Lee - Kesler method. The Antoine equation of β- phenylethanol was regressed. Associated with Wilson equation, the corresponding model parameters were obtained. The basic data and theoretical basis of β - phenylethano separation purification process were provided.
