<p>The invention relates to a device for separating a bio-degradable, intermolecular cyclic diester of an alpha-hydroxycarboxylic acid from substance mixtures that also contain the corresponding diester alpha-hydroxycarboxylic acid. Said diester is, in particular, lactic acid with dilactide and acid. The invention also relates to a method for separating dilactide from substance mixtures that is based on a modified, distillation method. The invention further relates to a polymerisation device, in particular for producing polylactide, to intended uses and to the devices as well as to the method.
