摘　　要：实验测定了水-醋酸-二异丙醚三元体系在293.15 K、303.15 K的液液相平衡数据。分别采用Othmer-Tobias和Bachman方程对实验数据进行了可靠性检验,相关性系数均大于0.983。绘制了三元液液平衡相图。Liquid–liquid equilibrium（LLE） data for the ternary system of water ＋ acetic acid ＋ diisopropyl ether at 293.15 K and 303.15 K have been measured under atmospheric pressure.The experimental data were correlated by the equations of Othmer-Tobias and Bachman,respectively.All the linear correlation coefficients are greater than 0.983.The LLE phase diagram of the investigated system at different temperature was given.
