Isobaric vapor-liquid equilibrium (VLE) data for the binary systems of cyclohexanol with isopropanol was measured at 101.3 kPa with a modified equilibrium still.The measured data were verified to satisfy the thermodynamical consistency by the Herington method.The t-x-y and x-y phase diagrams for the system were obtained.The VLE data for cyclohexanol-isopropanol were correlated with the Wilson model using the nonlinear least square method.The obtained model parameters were used to predict the binary VLE data.The predicted values obtained by Wilson equations fit well with the experimental values.%利用改进的平衡釜对环己醇与异丙醇组成的二元体系在常压下的气液相平衡关系进行了研究,测定了该二元体系在常压下的气液相平衡数据,绘制了环己醇-异丙醇在常压下的x-y,t-x-y相图,运用Herington 方程对实验数据进行了热力学检验,均符合热力学一致性.同时运用Wilson方程建立了数学模型,并求出了二元作用参数,预测的相平衡数据,与实验数据吻合.
