Alcohols In Non-polar Solvents Research Articles

Statistical Thermodynamics of Associated Solutions

Thermodynamic data for the solutions chloroform+benzene, acetone+chloroform, ethanol+chloroform, ethanol+acetone, and ethanol+ether are discussed in the light of a model for associated solutions which has been described previously. The theory in its original form, previously found satisfactory for solutions of alcohols in nonpolar solvents, proves satisfactory for the first two of these systems. To interpret the data for the remaining more complicated systems it is necessary to generalize the model to allow for interaction free energies which depend on temperature (presumably because of changes in vibration frequencies). The necessary generalization of the theory is described, and a consistent set of interactions for the ethanol systems is derived. The generalized theory should apply, with the limitations inherent in lattice theories, to most nonaqueous associated solutions.

Orientation Effects in Solutions of Alcohols

An attempt is made to relate the free energy, heat, and entropy effects involved in the solution of alcohols in nonpolar solvents with the molecular interactions in the solutions. A simple model for the alcohol molecules is proposed, and the thermodynamic functions for a one-dimensional array, and in a simple case for a three-dimensional array, are determined by the methods of statistical mechanics. The results for the three-dimensional array are used to examine the assumption of ``repeatable step'' association with a definite equilibrium constant, and cast some doubt on the justification for this assumption. It is concluded that a more complete treatment of the three-dimensional array should provide a satisfactory basis for the complete description of the experimental facts.
