Sažetak
Crystallization is an important unit operation used in many branches of industry because it is energy efficient way of separating and purifying compounds.[1] It is one of the most important unit operations in the pharmaceutical industry. The industrial control of crystallization is a difficult task because of the stochastic and often unpredictable behavior of the system. With the development of process analytical technology crystallization control has become possible because it has enabled real-time measurement of critical quality attributes. ATR-FTIR spectroscopy has been used to track the concentration during crystallization [2] but the procedure of developing calibration models is time-consuming. The rapid development of the calibration model is done by slowly heating excess solute in a solvent and collecting temperature and spectra. It is assumed that for each temperature the solubility equilibrium has been reached and spectra correspond to the solubility concentration. In this work, the excess amount of glycine was heated from 5 °C to 55 °C during the span of 4.5 hours. The amount of glycine was 5 % higher than the solubility at 55 °C. The particles were grounded with pestle and mortar to achieve a small size of crystals that dissolve quickly. The spectra were recorded every minute together with the temperature. The PLS calibration model relating spectra to saturation temperature was built. The model was tested on an independent data set obtained by repeating the experiment. The results indicate that the model can predict saturation temperature with relatively good accuracy (RMSEP=0.73).
