METHOD FOR THE PRODUCTION OF A MIXTURE OF LACTIDE DERIVATIVES
摘要
The present invention relates to three variants for preparing a mixture of cyclic diesters derived from lactic acid and especially a racemate of dilactide. This can proceed, as desired, from the corresponding a-hydroxycarboxylic acids, the corresponding cyclic diesters or oligomers of the corresponding a-hydroxycarboxylic acids.
