Purification of naphthalene and stearic acid by zone melting was studied. The effects of the crystallization velocity and mixing intensity of the melt on the purity of the crystal were investigated by applying the solution of the diffusion equation where the necessary boundary layer thickness was calculated from correlations in the literature. The calculated values are compared with experimental values. The results can be used for estimation of the optimum mixing intensity and crystallization velocity.
