ABSTRACT
A mathematical model based on convective diffusion was developed to describe the rate of dissolution form the surface of a compressed compact. Experimental studies were carried out to test the model. The basic experimental apparatus consisted of a modified rotating-filter-stationary basket dissolution test apparatus. Dissolution rates from rectangular and circular surfaces of an homologous series of p-aminobenzoate esters permitted testing the theory with respect to solubility, geometry, and agitation conditions. The correlation between experimental results and theory was reasonalby good considering that the test conditions were somewhat less than ideal.
