Chiral ionic liquids for enantioseparation of pharmaceutical products by capillary electrophoresis.
A chiral ionic liquid (IL), S-[3-(chloro-2-hydroxypropyl)trimethylammonium] [bis((trifluoromethyl)sulfonyl)amide] (S-[CHTA](+)[Tf(2)N](-)), which can be easily and readily synthesized in a one-step process from commercially available reagents, can be successfully used both as co-electrolyte and as a chiral selector for CE. A variety of pharmaceutical products including atenolol, propranolol, wa...
متن کاملEnantioselective Extraction of Ofloxacin Enantiomers Using Ester Alcohol L-Tartarate as Chiral Selector
The distribution behavior of ofloxacin enantiomers was examined in the aqueous and organic solvent of a two-phase system containing chiral selector L-tartarate. The effect of extraction equilibrium time, buffer pH, organic solvents and length of alkyl chain of L-tartarate on the partition coefficients and enantioselectivity of racemic ofloxacin were investigated, respectively. The L-tartara...
متن کاملCoordinating chiral ionic liquids.
A practical synthesis of novel coordinating chiral ionic liquids with an amino alcohol structural motif was developed starting from commercially available amino alcohols. These basic chiral ionic liquids could be successfully applied as catalysts in the asymmetric alkylation of aldehydes and gave high enantioselectivities of up to 91% ee.
متن کاملSeparation of ibuprofen drugs enantiomers by using chiral carbon nanotube with molecular dynamics simulation
Background: The separation of drug enantiomers in the pharmaceutical industry is of great importance since most organic compounds are chiral. The main purpose of this study was to calculate the binding energy of ibuprofen isomers interacting with the CNT, according to various adsorption configurations. Moreover, we have evaluated the performance of (16.4) chiral carbon nanotube for separation o...
متن کاملEfficient Extraction of Agarose from Red Algae Using Ionic Liquids
We explored the possibility of using ionic liquids (ILs) as medium for efficient extraction of agarose via dissolution of red algae under varying conditions of heating or microwave irradiation. As compared to conventional methods, a very high extraction yield of good quality agarose (as high as 39 wt%) could be achieved depending upon the nature of used IL and applied experimental conditions. P...
