| 摘 要： | 采用静态溶液总蒸气压法测定醋酸——丙酸在298.15k、308.15k、318.20k、328.10k、四组恒温下的气液平衡数据T、P、x.并用Mixom的间接法推算气液平衡时的气相组成(yi)、液相活度系数(γi),以及过量自由焓函数等。利用上述数据,由低压外推到常压,作了常压下的泡点计算。这样获得了由低压到常压的应用范围非常广泛的气液平衡数据。

STATIV METIHOD OF STUDY ON THE ISOTHERMAL VAPOR EQUILIBRIUM OF ACETIC ACID...... ACETONE BINARY |

| Abstract: | In this paper, in order to get four groups T. P. X, static solution of ov all vapor pressure method is used to measure acetic acid——acetone binary mixture in the absolute temperature 298. 15k, 318. 20k, 308. 15k, 328. 20k, MIXon indirect method, when vapor liquid is in equilibrium is abopted to calculate vapor phase composition(y) liquid phase activity cofficient(ri) and overagee free enthalpy function erc. with these data, bubble points calculations are don rom Iow pressure to ordinary pressure thus getting Vapor Iiquid equilibriu m data over the wide range from Iow pressure to ordinary pressure. Imperfections in studying vapor Iiquid eqnilibrium with the tradition "flow cycle method" are avoided. |
