Notes:
A study has been made to show that Maron's theory of the thermodynamic behavior of nonelectrolyte solutions is applicable to systems with low molecular weight solutes as well as polymers. In this connection were investigated three systems of varying degrees of complexity, namely: (1)carbon tetrachloride-cyclohexane, (2)acetone-chloroform, and (3)water-ethyl alcohol. The first of these systems yields a small positive interaction parameter μ which is essentially independent of volume fraction v2 but which decreases with temperature T. On the other hand, the system acetone-chloroform gives μ's which are large, negative, and strongly dependent on both T and v2. Similarly the system water-ethyl alcohol yields μ's which vary with both v2 and T, but in this case they are large and positive. The relations deduced for the μ's as a function of T and v2 reproduce very satisfactorily the available thermodynamic data for these systems. A discussion is also given of the significance of the observed interaction parameters.
