DL-Lactide is a physical mixture of racemic l-and d-monomers in the same proportion. DL-LA is produced by DL-lactic acid polymerization. Because DL-lactic acid itself is racemized, DL-LA does not need to consider the racemization of lactic acid or lactide, Racemic lactide can be synthesized by extensive operation, which has simple process and low cost of raw material.
The disadvantage of DL-LA is that the single yield of DL-LA is not more than 50% , and the other 50% is DL-LA. That is to say, the ratio of the racemic lactide and the racemic lactide produced by DL-lactic acid is 1:1. L-LA with high yield could be obtained by avoiding racemization of l-lactic acid.
Since only l-lactic acid is biologically active in humans, only L-lactic acid-degrading enzymes are present in the body. Only l-lactic acid is used in food and medicine.
For Chemical and light industry lactic acid, no configuration requirements, can be used DL-lactic acid. Similarly, DL-LA has different application range compared with L-la.
