Chemical Properties:
  1. White crystalline powder
  2. Lactide is a colorless, transparent flake or needle-like crystal, with a melting point of 93-95°C, easily soluble in chloroform, ethanol, but insoluble in water. Easy to hydrolyze, easy to polymerize. It can be used to produce medical high polylactic acid and cyclic esterification agent.
  1. DL-Lactide is used to produce 2-hydroxy-propionic acid 1-(1-phenyl-ethoxycarbonyl)-ethyl ester. It acts as an important raw material and an intermediate used in organic synthesis, pharmaceuticals, agrochemicals and dyes. It is involved in enzymatic alcoholysis to produce both alkyl (R)-lactates and alkyl (S,S)-lactyllactates.DL-Lactide is often used as a protective layer in wound coatings, or as anchors, screws or mesh in surgery, since it degrades in about six months to the innocuous lactic acid.
  2. Enzymatic alcoholysis of this racemic lactide catalyzed by commercial Novozym® 435 produces both alkyl (R)-lactates and alkyl (S,S)-lactyllactates in good yield and high enantiopurity.
  3. The racemic lactide undergoes an enzymatic alcoholysis reaction catalyzed by the commercially available Novozym(R) 435 to generate alkyl (R)-lactate and alkyl (S, S)-lactyl lactate, which has a high The yield and enantiomeric purity.
