| 摘 要： | 采用改进的倾斜式稀释膨胀溶液在298.15K 测定液体苯(1)——环已烷(2)的过量体积,并与文献值比较证明倾斜式稀释膨胀计测得数据可靠。又对未见报导的二甲苯(1)——环已烷(2)溶液在299.15K、288.15K 测定不同浓度下的摩尔过量体积数值,并用 Redich—Kister 方程对全浓度范围内的摩尔过量体积进行关联计算,从而为溶液热力学提供有价值的热力学数据。

| Abstract: | Meaurement of molar of excess volumes of benzene (1)—cyclohexane(2) at 298.15K is made by means of an improved tilting dilution dilatoe-meter,compared with data published,it is proved that the tilting dilutiondilatometer is quite reliable.With it,the molar excess volumes for thesolution,not reported yet,xylene (1)—cyclohexane (2) at 298.15Kand 288.15K are determined under various concentrations.The molarxcess volumes covering all molar concentration is corretively calculatedeby using Redich-Kister equation,therefore providing valuable thermodynamic data for solution thermodynamics. |
