Chiral task-specific solvents for mandelic acid and their impact on solution thermodynamics and crystallization kinetics

Tulashie, Samuel K.; Langermann, Jan von; Lorenz, Heike; Seidel-Morgenstern, Andreas (University of Cape Coast, 2010)

The synthesis and application of enantiopure short-chain mandelic acid esters as chiral task-specific solvents were investigated for the determination of hetereochiral interactions between chiral solutes and chiral solvents. ...
Potential of chiral solvents for enantioselective crystallization. 1. evaluation of thermodynamic effects

Tulashie, Samuel Kofi; Lorenz, Heike; Hilfert, Liane; Edelmann, Frank Thomas; Seidel-Morgenstern, Andreas (University of Cape Coast, 2008)

It can be expected that a chiral solvent possesses a certain potential to discriminate between two enantiomers by creating specific weak interactions and forming disastereomeric complexes which have different physical ...
Solid-liquid equilibria of mandelic acid enantiomers in two chiral solvents: experimental determination and model correlation

Tulashie, Samuel Kofi; Kaemmerer, Henning; Lorenz, Heike; Seidel-Morgenstern, Andreas (University of Cape Coast, 2010)

A study of the ternary solubility phase diagrams of enantiomeric mandelic acid species in the chiral solvents (S)-ethyl lactate and (2R,3R)-diethyl tartrate has been carried out. The solubility measurements were conducted ...
Solid-phase and oscillating solution crystallization behavior of (þ)- and ()-n-methylephedrine

Tulashie, Samuel Kofi; Polenske, Daniel; Seidel-Morgenstern, Andreas; Lorenz, Heike (University of Cape Coast, 2016)

This work involves the study of the solid-phase and solution crystallization behavior of the N-methyl ephedrine enantiomers. A systematic investigation of the melt phase diagram of the enantiomeric N-methylephedrine system ...
Solubility of mandelic acid enantiomers and their mixtures in three chiral solvents

Tulashie, Samuel Kofi; Lorenz, Heike; Seidel-Morgenstern, Andreas (University of Cape Coast, 2010)

A systematic study of the ternary solubility phase diagrams of chiral mandelic acid species in the chiral solvents (S)-methyl lactate, (S)-propyl lactate, and (S)-butyl lactate has been carried out. Solubility measurements ...
Ternary solubility phase diagrams of mandelic acid and n-methylephedrine in chiral solvents with different carbon chain lengths

Tulashie, Samuel Kofi; Heike, Lorenz; Malwade, Chandrakant Ramkrishna; Seidel-Morgenstern, Andreas (University of Cape Coast, 2010)

Ternary solubility phase diagrams of mandelic acid and N-methylephedrine species in chiral solvents, (S)-methyl lactate, (S)-propyl lactate, and (S)-butyl lactate, have been determined. Solubility measurements were performed ...
