Abstract The solubilities of pentane, 2-methylbutane (isopentane) and cyclopentane were measured in liquid nitrogen at 77.4 K by the filtration method. The solubilities of the C5 hydrocarbons in liquid nitrogen at 77.4 K vary from 1.8×10−8 mole fraction for cyclopentane, to 3.0×10−8 mole fraction for pentane and 3.2×10−7 mole fraction for 2-metylbutane. Correlations between the solubilities of alkanes, alkenes and cyclic hydrocarbons in liquid nitrogen, and some properties of solutes [normal boiling point T b , enthalpy of vaporization at normal boiling point ΔH b and the mean of the enthalpy of vaporization and the enthalpy of melting [(ΔH b +ΔH m )/2] are presented.
