Application of Direct Crystallization for Racemic Compound Propranolol Hydrochloride

Journal of Pharmaceutical Sciences, 2007
The application of direct crystallization integrating with chromatography to the resolution of a racemic compound propranolol hydrochloride was studied and the crystallization progression was clearly illustrated in terms of the diagram of solubility and metastable zone widths with different enantiomeric compositions.

Application of preferential crystallization to resolve racemic compounds in a hybrid process [PDF]

Chirality, 2006
AbstractThe application of preferential crystallization is at present limited to conglomerate forming systems, which cover only a minor part of chiral substances. In this paper, a hybrid process is proposed that extends the applicability of the preferential crystallization principle to the more common racemic compound forming systems.

Potential of different techniques of preferential crystallization for enantioseparation of racemic compound forming systems. [PDF]

Chirality, 2009
Recently the feasibility of preferential crystallization for enantioseparation of racemic compound forming systems has been demonstrated (Lorenz et al., Application of preferential crystallization to resolve racemic compounds in a hybrid process ...

Phase Diagram of a Chiral Substance Exhibiting Oiling Out. 2. Racemic Compound Forming Ibuprofen in Water [PDF]

, 2012
This work investigates the ternary phase behavior of the two enantiomers of ibuprofen and water. The two enantiomers crystallize as a racemic compound and exhibit a thermodynamically stable liquid-liquid phase separation (LLPS), which extends over the ...

Racemic compound versus conglomerate: concerning the crystal chemistry of the triazoylketone, 1-(4-chlorophenyl)-4,4-dimethyl-2-(1H-1,2,4-triazol-1-yl)pentan-3-one [PDF]

, 2014
The triazoylketone discussed in this paper crystallises from racemic solutions as a conglomerate. Here, we report the ternary phase diagram confirming the conglomerate behaviour of this molecule. Through computation we also explore the underlying reasons
