Abstract
A detailed knowledge of the metastable zone width (MSZW) and nucleation kinetics is vital for the design of batch cooling crystallization processes. Factors such as cooling rate and impeller speed affect the MSZW and nucleation kinetics. Crystallization and dissolution temperatures were measured as a function of cooling rate and impeller speed during the batch cooling crystallization of p ‐aminobenzoic acid (pABA) from ethanol in a 0.5‐L stirred‐tank crystallizer. The polythermal experimental data were analyzed using the Nyvlt and first principles‐based Kashchiev‐Borissova‐Hammond‐Roberts (KBHR) methods. In all experimental cases, the latter model revealed that the nucleation process of pABA in ethanol was dominated by an instantaneous nucleation mechanism. The Nyvlt and KBHR analyses delivered a range of parameter values associated with a power‐law model describing the nucleation rate as well as the concentration of nuclei.
