Direct chiral resolution of tartaric acid in food products by …
WebChiral resolution of native DL-tartaric acid was achieved by ion-pair capillary electrophoresis (CE) using an aqueous-ethanol background electrolyte with (1R,2R)- (-)-1,2-diaminocyclohexane (R-DACH) as a chiral counterion. Factors affecting chiral resolution and migration time of tartaric acid were studied. WebBelow is a list of our chiral resolution method: Chiral resolution by crystallization The separation of racemates into pure enantiomers through crystallization is an important industrial process. The crystallization method has the advantages of simple operation, high product purity, and easy realization of industrial production. greenview county real estate
