- Abstract
- The selective crystallization of either R or ç polymorph of glycine was obtained by both static and dynamic membrane
crystallization. The membrane matrix acts as a selective medium for solvent evaporation by modulating the rate for the achievement
of supersaturation. In static membrane system this was obtained by changing the concentration of the stripping solution inside the
membrane fibers, whereas in dynamic configuration it was obtained by varying the recirculation solution velocity. The increase in
solvent evaporation rate induced an increase in the metastable zone width with effects on the heat and mass transfer during the
nucleation kinetics. The consequent switching between a thermodynamically and a kinetically controlled nucleation stage resulted
in the production of either a stable or metastable form of glycine. As control of polymorphism is critical in many pharmaceutical,
electronic, and food applications, the possibility of inducing polymorph selection during a crystallization process by using membranebased
techniques might represent a remarkable improvement. (literal)
