Abstract

A new CHIRAL SEPARATION technology, aqueous two-phase extraction, was proposed for the separation of racemic mandelic acid.The distribution behavior of MANDELIC ACID ENANTIOMERS was investigated in aqueous two-phase systems composed of polyethylene glycol and ammonium sulfate containing b-cyclodextrin as chiral selector. The influences of the pH, the mass fraction of polyethylene glycol and ammonium sulfate, the polymerization degree of polyethylene glycol, the initial concentration of b-cyclodextrin, MANDELIC ACID ENANTIOMERS and extractive temperature on the distribution behavior were studied respectively. The results show that b-cyclodextrin is inclined to recognize L-enantiomer; under the optimized conditions, the separation factor reaches 2.46 and the enantiomeric excess is 42.13% in the top phase and 40.43% in the bottom phase, respectively. Aqueous two phase chiral-extraction with strong CHIRAL SEPARATION ability, plays great role in preparative separation of racemic compounds and is important for the development of AQUEOUS TWO PHASE EXTRACTION technique.
