Abstract
The solubilities of hex-1-ene, hexane and cyclohexane have been measured in liquid nitrogen at a temperature of 77.4 K by the filtration method. The solubilities of the C6 hydrocarbons in LN2 at 77.4 K vary from 0.5 × 10–8 mole fraction for cyclohexane, to 0.7 × 10–8 mole fraction for hexane and 0.16 × 10–6 mole fraction for hex-1-ene. The results are compared with the solubilities calculated on the basis of the Scatchard–Hildebrand equation of regular solution theory. Correlation between the solubilities of alkanes, alkenes and cyclic hydrocarbons in liquid nitrogen, and some properties of solutes {normal boiling point (Tb), critical point (Tc), heat of vaporization at normal boiling point (ΔHb), the mean of the heat of vaporization and the enthalpy of melting [(ΔHb+ΔHm)/2] and Lennard–Jones force constant (ε/kB} are presented.
