Characterization of Crystal Populations of Vitamin C by Hyperbolic Tangent Distribution Functions

Abstract

The four parameter hyperbolic tangent distribution family is used for characterizing the size distributions of vitamin C crystals. The crystals were obtained in batch experiments in a laboratory scale agitated crystallizer under different experimental conditions. It is demonstrated by the results of matching that hyperbolic tangent distribution functions describe the experimental data well thus the crystallization process of vitamin C can satisfactorily be characterized by means of these distribution functions.
