Employing a method similar to initial derivation and using solubility curve data and effective parameter determination, a mathematical model for calculation of the linear crystal growth rate in crystallization process has been developed. Dilution crystallization is an important unit operation in manufacturing of particles and is used for obtaining crystallization kinetic. The anti- solvent volume is the effective parameter in system at 25 0 C. An advantage of this method is that concentration driving force affects the linear crystal growth rate and crystallization occurs in metastable zone region. The results from this study show that the model is accurate as procedures which use weight and particle size to find crystal properties.
