✦ Synopsis
The interfacial energies between m-acetotoluide and four saturated hydrocarbon solvents, n-hexane, n-heptane, cyclohexane, and decahydronaphthalene, were determined using the Ostwald-Fruendlich equation. Dissolution rates were determined in a descending direction to obtain interfacial control. The dissolution rates were found to decrease as the interfacial energy increased. The dissolution rates were also found to decrease as the saturation solubility of m-acetotoluide in the four solvents increased. An interfacial dissolution model, in which the interfacial region is associated with the solid phase rather than the liquid phase, is postulated.
