MANUFACTURING LACTIDE FROM LACTIC ACID

摘要

Disclosed is a method for manufacturing D-lactide from liquid D-lactic acid and a method for manufacturing D-polylactic acid with a weight-average molecular weight 50,000-20,000 g/mol from the prepared D-lactide. The disclosed method is advantageous in that D-lactide can be prepared in high yield through a relatively simple process as compared to the existing method. Thus, the cost for producing D-polylactic acid from the D-lactide can be reduced.
