Interpretation of distribution coefficients of p-alkylpyridines by a modified regular solution theory.

The hypothetical hexadecane-octane distribution coefficients for the alkylpyridines were deduced from the corresponding oil-water distribution data. The values were analyzed by a modified regular solution theory. A good correlation was noted by including the Flory-Huggins entropy factor in the calculation and by considering the deviation from the geometric… (More)
