CCI4、C2HCl3和C2CI4二元及三元体系恒压汽液平衡的测定
Phase Equilibria for Binary and Ternary Systems of CCl4,C2HCl3 and C2Cl4
【摘要】 用改进后的常减压汽液双循环 Rose 釜,在常压下测定了 CCl4-C2HCl3-C2Cl4二元及三元体系的恒压汽液平衡数据。并用 Wilson 方程、NRTL 疗程、UNIQUAC 方程以及 Martin-Hou（侯）-81状态方程进行了关联和预测,计算值与试验值误差甚小,为设计精馏塔提供了依据。
【Abstract】 The VLE data of three binary systems,carbon tetrachloride（CCl4）-trichloro-ethylene（C2HCl3）,carbon tetrachloride-tetrachloroethylene（C2Cl4）,and trichloro-ethylene-tetrachloroethylene,and one ternary system CCl4-C2HCl3-C2Cl4,were deter-mined in an improved Rose Still.The compositions of VL phases were analyzedby means of chromatography and refractometry.The parameters of three binarysystems were correlated by Wilson,NRTL and UNIQUAC equations respectively.The equilibrium temperatures and vapor compositions of the above four systemswere predicted by Martin-Hou equation.Compared with the experimental data,all the calculated values were satisfactory.
