CHIRAL ADSORBENTS, METHODS OF THEIR PREPARATION, CROSS-LINKED POLYMER, TARTARIC ACID DERIVATIVES AND METHODS OF THEIR PREPARATION Russian patent published in 1998 - IPC

FIELD: polymer sorbents. SUBSTANCE: chiral adsorbents are provided based on cross-linked polymerized derivatives of dicarboxylic acids, diamines, and diols chemically bound to carrier. Derivatives of these compounds can be polymerized through radical polymerization or through hydroxylation in presence of solid carrier. Chiral adsorbents are efficient for chromatographic separation of racemic mixtures of enantiomers. EFFECT: facilitated separation of enantiomers. 22 cl, 4 ex
