Solubility of pentane, 2-methylbutane, and cyclopentane in liquid nitrogen at 77. 4 K
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 C[sub 5] hydrocarbons in liquid nitrogen at 77.4K vary from 1.8x10[sup [minus]8] mole fraction for cyclopentane, to 3.0x10[sup [minus...

Zusammenfassung: | 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 C[sub 5] hydrocarbons in liquid nitrogen at 77.4K vary from 1.8x10[sup [minus]8] mole fraction for cyclopentane, to 3.0x10[sup [minus]8] mole fraction for pentane and 3.2x10[sup [minus]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[sub b], enthalpy of vaporization at normal boiling point [Delta]H[sub b] and the mean of the enthalpy of vaporization and the enthalpy of melting ([Delta]H[sub b] + [Delta]H[sub m])/2] are presented. |
