  • CLEANING DEVICE FOR SEPARATING DILACTIDE FROM MIXTURES, POLYMERISATION DEVICE, METHOD FOR SEPARATING DILACTIDE FROM MIXTURES AND USE THEREOF
    Publication number: 20100249364
    Abstract: The present invention relates to a device for separating a biodegradable, intermolecular cyclic diester of an alpha-hydroxycarboxylic acid from material mixtures which contain in addition the alpha-hydroxycarboxylic acid of the diester corresponding thereto. In particular, the diester is thereby dilactide and the acid lactic acid. Furthermore, the present invention relates to a method for separating dilactide from material mixtures, which is based on a modified, distillative method. In addition, the present invention describes a polymerisation device, in particular for preparing polylactide. Likewise, purposes of use of both the devices and of the method are indicated.
