Development of a mathematical model for batch crystallization of fesoterodine fumarate, an active pharmaceutical ingredient, in 2-butanone is presented. The model is based on population, mass and energy balances, and takes into account nucleation, crystal growth and agglomeration. Equilibrium solubility was determined experimentally by ATR-FTIR spectroscopy. Kinetic parameters were determined by fitting of experimental and simulated concentration curves and particle size distributions for six crystallization experiments, performed under different operating conditions. The model was validated and the results show good agreement with experimental data. This work is licensed under a Creative Commons Attribution 4.0 International License.
U radu je prikazan razvoj matematičkog modela šaržne kristalizacije fezoterodin fumarata, aktivne farmaceutske tvari, u 2-butanonu. Model se temelji na populacijskoj bilanci te bilanci tvari i energije, a uzima u obzir nukleaciju, rast kristala i aglomeraciju. Ravnotežna topljivost određena je eksperimentalno pomoću spektroskopije ATR-FTIR. Kinetički parametri su određeni primjenom eksperimentalnih i simuliranih krivulja koncentracije i raspodjele veličine čestica za šest kristalizacijskih eksperimenata provedenih pod različitim uvjetima. Model je validiran i rezultati su u skladu s eksperimentalnim podatcima. Ovo djelo je dano na korištenje pod licencom Creative Commons Imenovanje 4.0 međunarodna.
