Coupling Viedma Ripening with Racemic Crystal Transformations: Mechanism of Deracemization

Coupling Viedma Ripening with Racemic Crystal Transformations: Mechanism of Deracemization
Christos Xiouras, Joop H. Ter Horst, Georgios D. Stefanidis, Tom Van Gerven
In this work, we develop a kinetic model to study the mechanisms through which deracemization occurs when a seeded solvent-mediated racemic crystal transformation to conglomerate takes place under grinding−racemization conditions. The model explains recent experimental observations and shows that the new process leads to fast and complete deracemization through a combination of second order asymmetric transformation and Viedma ripening.
