Chromatographic Separation of Racemates of Alcohols Using Porous Coordination Compounds of Zinc and Vanadium(IV) with Lactate and β-Cyclodextrin

It was shown that the efficiency of chromatographic separation of the racemates of 2-butanol, 2-hexanol, 3-hexanol, and 1-phenylethanol on columns with coordination compounds [Zn₂(bdc)(S-Lact)(DMF)]_n (bdc^2- = 1,4-benzenedicarboxylate, S-Lact^– = (S)-lactate) and Na₇{(VO)₇Na₇(H₂O)₇(β-CD)₂} (β-CD = β-cyclodextrin) does not depend on the size of the alcohol molecule. It was found that in the case of the 1-phenylethanol racemate separation with [Zn₂(bdc)(S-Lact)(DMF)]_n the enantiomeric excess of the alcohol varies inversely with the viscosity of the solvent.
