dc.description.abstract | The expression that relates the ideal mole fraction solubility of a crystalline compound to physico-chemical properties of the compound includes a term involving the difference in the heat capacities of the solid and liquid forms of the solute, Δ C P . There are two alternate conventions which are employed to eliminate this term. The first assumes that the term involving Δ C P , or Δ C P itself, is zero. The alternate assumption assigns the value of the entropy of fusion to the differential heat capacity. The relative validity of these two assumptions was evaluated using the straight-chain alkyl para-aminobenzoates as test compounds. The heat capacities of the solid and liquid forms of each of the para-aminobenzoates, near the respective melting point, were determined by differential scanning calorimetry. The data lead one to conclude that the assumption that the differential heat capacity is not usually negligible and is better approximated by the entropy of fusion. | en_US |
