| 摘 要： | 测定了压力0.5~3.0 MPa、温度233.15~293.15 K条件下CH4/m-C9H12(即均三甲苯)体系的二元汽液相平衡数据,用PR方程对CH4/m-C9H12体系的汽液相平衡数据进行关联,得到了二元交互作用参数。实验数据的偏差分析证明PR方程适合描述该体系。基于以上结果,并结合文献数据,计算了CH4/C2H4/m-C9H12三元体系的相平衡数据,并绘制了该三元体系的相图。结果表明,CH4和m-C9H12的相容性与C2H4和m-C9H12相比差异较大,m-C9H12是一种适合吸收C2H4的溶剂。

| Abstract: | Isothermal vapor-liquid equilibrium(VLE) data for the CH4/m-C9H12(i.e.mesitylene) binary system have been measured under pressures of 0.5 to 3.0MPa,and temperatures of 233.15 to 293.15K.The VLE data were correlated by means of the Peng-Robinson equation and the interaction coefficient was calculated.Combination of the results with other data in the literature allowed the phase equilibrium data of the CH4/C2H4/m-C9H12 ternary system to be calculated.The phase diagram was also derived.The ternary system phase... |
