摘　　要：裂解C_9是乙烯装置的副产,产量很大,对其研究具有重要的经济意义。实验测定裂解C_9汽液平衡数据,计算各组分之间相对挥发度,以确定精馏过程分离条件;测定裂解C_9与溶剂之间汽液平衡数据,计算各主要组分之间的相对挥发度,通过气质联用色谱法分析实验结果,对比分析不同溶剂对相对挥发度的影响,筛选出甘油作为裂解C_9萃取精馏实验的最佳溶剂。本文研究为进一步放大实验、裂解C_9的精馏预处理及萃取精馏提取C_9馏分提供依据。Cracked C9 arene is the important byproduct from ethylene equipment, and its output is enormous, so there is momentous economic significance on the study of C9 arene. Vapor-liquid equilibrium data of C9 arene were received through gas chromatograph-mass spectrometer, and the distillation condition was ascertained. Vapor-liquid equilibrium data of C9 arene-solvent could be also received. The best solvent, diglycerol, was selected by the measurement of vapor-liquid equihbrium data and the analysis of relative volatility, and glycerin will be used in the exaction distillation. The result of this study will provide the basis for further experiment, distillation and exaction distillation of refining trimethylbenzen fraction from C9 arene.
