Two different compounds have formed from liquid enantiomeric (R-) and racemic α-methylbenzylamine (α-MBA, named also as 1-phenylethylamine, 1-FEA) with supercritical fluid CO2. The crystalline solids have been characterized by elemental CHN analysi

A novel co-crystal of trans-(R,R)-1,2-cyclohexanediol and (R,R)-tartaric acid (with 1:1 molar ratio, 1) has been found to be a key crystalline compound in the improved resolution of (±)-trans-1,2-cyclohexanediol by supercritical fluid extraction. Th

A simple method for the resolution of racemic trans -1,2-cyclohexanediol enantiomers is presented in this paper. The chiral discrimination was performed by tartaric acid via diastereomeric complex formation. The diastereomeric complexes were formed b
