Solubility of Solid Hexane and Cyclohexane in Liquid Argon at 87.3 K
Journal of Solution Chemistry(2001)
摘要
The solubilities of solid hexane and cyclohexane in liquid argon at 87.3 K have been measured by the filtration method. The hexane and cyclohexane content in solution was determined using gas chromatography. The solubilities of the C 6 hydrocarbons in liquid argon at 87.3 K are (0.56 ± 0.11) × 10 -7 mole fraction for hexane and (1.04 ± 0.30) × 10 -7 mole fraction for cyclohexane. The Preston–Prausnitz method was used for calculation of the solubilities of solid hexane and cyclohexane in liquid argon in the temperature range 84–110 K. The values of the solvent–solute interaction constant l 12 were also calculated.
