摘　　要：利用汽液双循环的玻璃平衡釜测定了327.65K和332.65K下3 羟基丁醛和3 羟基丁酸体系的汽液平衡数据。采用积分法对其进行了热力学一致性检验,并用Wilson模型对该实验数据进行了关联。方程的计算平均误差分别为0.0279和0.0776,这表明Wilson模型适合本体系的汽液平衡数据的关联和预测。The isothermal vapor-liquid equilibrium data for the binary system of 3-hydroxybutysic acid and 3-hydroxybutyraldehyde at 327.65 K and 332.65 K was measured by using a vapor liquid-recycled vapor-liquid equilibrium still. Integral method was used to examine the thermodynamic consistency, and the Wilson mode was used to correlate the experimental data of the system. The calculated mean deviations of the equation were 0.0279 and 0.0776 respectively. The agreement between calculated and experimental data was satisfactory.
