Resolution of some racemic, D, L aminoacids on an ion exchanger containing iminodi (methanephosphonic) groups in amino-copper form

  • W. Szczepaniak
  • W. Ciszewska


An ion-exchanger with imine (dimethanephosphonic) groups in amino-copper form has been applied for the resolution of several amino acid racemates. It has been shown that there are differences in the partition coefficients of enantiomers measured under static conditions. Ligand-exchange chromatography permitted the separation of tyrosine, phenylalanine, cystine, histidine and tryptophane enantiomers.
