The lactide is monomer for production of polylac- tide – biodegradable polymer that use as an ecological packagingmaterial. In an industry the two-stage lactide synthesis is applied. At first, lactic acid condenses into the oligomer using Sn-octanoate catalyst, then oligo- mer depolymerizes to lacti...
