| abstract | A process for treating a mixture of R,R- and S,S-lactide is provided. The process involves contacting the mixture with an aliphatic alcohol and an enzyme to produce a mixture comprising aliphatic ester of lactic acid corresponding to one lactide enantiomer and the aliphatic ester of lactyllactic acid corresponding to the other lactide enantiomer; separating the mixture from the enzyme, and recycling the enzyme to the process; and separating the aliphatic ester of lactic acid from the aliphatic ester of lactyl-lactic acid by fractional distillation. Also provided are processes for the production of S-lactic acid, S,S-lactide, poly-S-lactic acid, R-lactic acid, R,R-lactide, poly-R-lactic acid and stereocomplex polylactic acid. |
