| titleOfInvention | Lactide recovery method |
| abstract | The present invention provides a method for highly expressing the catalytic function of magnesium oxide as a depolymerization catalyst in order to efficiently recover high purity lactide from a polymer containing a polylactic acid component. In recovering lactide from a polymer containing a polylactic acid component, magnesium oxide having a surface area of 5 m 2 / g or more is added to the polymer in an amount of 0.1 to 10 per 100 parts by weight of the polylactic acid component in the polymer. A method for recovering lactide by adding parts by weight and heating to a temperature of 200 to 300 ° C. When magnesium oxide is heat-treated in a temperature range of 300 to 600 ° C., or when the surface hydroxyl group of magnesium oxide is replaced with a carbonate radical, lactide with high optical purity can be recovered more effectively.
