摘　　要：用自行设计的液液平衡装置在常压和30℃下测定了3-氰基吡啶、水、苯三元体系的液液平衡数据,并用NRTL方程进行了关联,实验数据和计算结果基本一致。Liquid-liquid equilibrium(LLE)data for the ε-cyanopyridine. water and benzene ternary system have been determined under atmospheric pressure and at 30℃ in an equilibrium equipment designed by the authors. The NRTI, equation is used to correlate the LLE data for this system. The result of the calculated value is in satisfactory agreement with the experiment data.
