✦ Synopsis

Approximate

analytical solutions to the transport equations describing the heat or mass transfercontrolled growth or dissolution of an isolated sphere are discussed and critically evaluated. The predictions of these equations are compared with finite-difference and similarity solutions. Recommendations are presented for using particular analytical expressions to evaluate the radius-time behavior of the spherical particle for various ranges of the two dimensionless groups of the problem.

Poorly soluble crystals of tolbutamide were modified in the presence of a soluble polymer or surfactant by the spherical crystallization technique, the objective being to improve the dissolution rate and to transform platelet crystals into spherical agglomerates. An HCI solution was added to a tolbu
