摘　　要：建立了中低压体系相平衡数据的测定方法,使用静态法测定了正丁烷-1-丁烯-甲乙酮-环丁砜体系的多元气液相平衡数据。利用UNIQUAC热力学模型对所测定的二元TPx或TPxy数据进行了参数回归,并对该体系的三元数据进行了预测。与实验结果对比发现,该模型具有可靠性,对压力预测的平均相对偏差为0.88%,对气相组成预测的平均偏差为1.33%。The determination method of phase equilibrium data from low to medium pressure is established. The gas-liquid equilibrium data of n-butane-1-butene-MEK-Sulfolane are determined with a static method. The activity coefficient models of UNIQUAC are used to correlate and predict the experimental data, the predicted result shows that the UNIQUAC model are basically satisfactory, The average relative error of pressure prediction is 0.88 %, and the average error of gas phase composition prediction is 1.33 %.
