Entropy of transfer of n-nitroalkanes from n-octane to water at 25�C

1984

Entropy of transfer of nitromethane, nitroethane, 1-nitrobutane, 1-nitropentane, and 1-nitrohexane from n-octane to water at 25°C is calculated using an electrostatic model. The calculations indicate that the electrostatic transfer entropy depends primarily on the dipole moment and the size of the-C−NO2 group, showing a trend which is similar to that previously found for the transfer free energy of the same process.

Free energy of transfer ofn-nitroalkanes fromn-octane to water at 25�C

1983

Calorimetric determinations of the thermodynamics of transfer of nitromethane, nitroethane, 1-nitrobutane, 1-nitropentane, and 1-nitrohexane from n-octane to water at 25°C have been made. Transfer free energies calculated by four different models agree reasonably well with observations. Calculations indicate that the dipolar part of the transfer free energy depends only on the dipole moment and size of the-C−NO2 group and is independent of the length of the alkyl chain in nitroalkanes.
