Development of a new method based on chiral ligand-exchange chromatography for the enantioseparation of propranolol
A new chromatographic procedure was proposed for the separation of propranolol (PRN) enantiomers based upon enantioselective chiral ligand-exchange chromatography. The separation was carried out on a short C8 column leading to considerably short separation time. L-alanine and Cu2+ were applied as chiral selector and central bivalent complexing ion, respectively. It was found that the kind of co...

متن کاملIsotope effects of neodymium in different ligands exchange systems studied by ion exchange displacement chromatography
The isotope effects of neodymium in Nd-glycolate ligand exchange system were studied by using ion exchange chromatography. The separation coefficients of neodymium isotopes, ε's, were calculated from the observed isotopic ratios at the front and rear boundaries of the neodymium adsorption band. The values of separation coefficients of neodymium isotopes, ε's, for the Nd-glycolate ligand exchang...
متن کاملUsability of online-coupling ion exchange chromatography ICP-AES/-MS for the determination of trivalent metal complex species under acidic conditions
The determination of metal complex species in aqueous solutions by using chromatographic techniques is potentially affected or even impossible due to species decomposition during the separation. An often used technique for slower exchanging metal ions is ion exchange chromatography (IC), which is used for the separation and quantification of 1-1-complexes of trivalent metal ions. The test set c...
متن کاملThe Effect of Temperature on Uranium Isotope Effects Studied by Cation Exchange Displacement Chromatography
The uranium isotope effect in the exchange system uranyl(VI)-malate ligand at 288–343 K has been studied by ion exchange displacement chromatography. At all temperatures 235U is enriched at the front of the uranium band. The single stage separation coefficient, (e =a – 1), increased from (0.9 ± 0.1)× 10 at 288 K to (2.9 ± 0.3)× 10–4 at 343 K. The equilibrium constant of the isotope exchange rea...
متن کاملStructural Investigation of the Ligand Exchange Reaction with Rigid Dithiol on Doped (Pt, Pd) Au25 Clusters
The ligand exchange reaction between heteroatom doped (Pd, Pt) Au25(2-PET)18 (2-PET = 2-phenylethylthiolate) clusters and enantiopure 1,1′-binaphthyl-2,2′dithiol (BINAS) was monitored in situ using chiral highperformance liquid chromatography (HPLC). During the ligand exchange reactions, replacement of two protecting thiols (2PET) with one new entering BINAS ligand on the cluster surface occurs...
