Thermodynamics of Oiling-Out in Antisolvent Crystallization. II. Diffusion toward Spinodal Decomposition

The extensive use of antisolvent crystallization for poorly soluble chemicals is hindered by oiling-out. This study delves into solute diffusion kinetics upon antisolvent addition. We conducted time-dependent simulations on a hypothetical…
