METHOD FOR PRODUCING a-HYDROXYCARBOXYLIC ACID DIMERIC CYCLIC ESTER |
| abstract |
Provided is a method for producing a high purity α-hydroxycarboxylic acid dimeric cyclic ester while heavy-component formation from an α-hydroxycarboxylic acid oligomer is suppressed. An α-hydroxycarboxylic acid dimeric cyclic ester is obtained by performing a depolymerization reaction in the coexistence of an inorganic acid or an inorganic acid salt or a mixture thereof; and an organophosphorus compound. |
