Excess thermodynamic properties of binary liquid mixtures containing cyclohexylamine at 30�C

Abstract

The excess volumes of mixing of cyclohexylamine with n-hexane, n-heptene, n-octane, n-nonane, benzene, toluene, nitrobenzene, chlorobenzene and bromobenzene have been measured at 30°C. For all systems except for n-hexane, V E is positive over the entire mole fraction range. For the n-hexane mixtures, a sigmoid curve is obtained with negative V E at high mole fraction of amine.
