| abstract | The invention provides one for the treatment of R, R-lactide and S, the method for the mixture of S-lactide. The method relates to: described lactide mixture is contacted with fatty alcohol and/or alcoholates, thereby form R, R-lactyl lactate aliphatic alcohol ester and S, the mixture of S-lactyl lactate aliphatic alcohol ester; Make subsequently described R, R-lactyl lactate aliphatic alcohol ester and S, the mixture of S-lactyl lactate aliphatic alcohol ester contacts with enzyme, comprises corresponding to a kind of lactic acid aliphatic alcohol ester of lactide enantiomter and corresponding to the mixture of the lactyl lactate aliphatic alcohol ester of another kind of lactide enantiomter to prepare; And recovery product. The present invention also provides for the preparation of S-lactic acid, S, S-lactide, poly--S-lactic acid, R-lactic acid, R, the method for R-lactide, poly--R-lactic acid and the three-dimensional compound of PLA. |
