Apparatus and method both relating to polymer synthesis |
| abstract |
The present invention provides a method and apparatus for producing polylactic acid by depolymerizing lactic acid oligomers and subjecting the obtained lactide to ring-opening polymerization, through which lactide can be efficiently obtained. The present invention relates to a lactide production apparatus for continuously or intermittently producing lactide, comprising: a depolymerization device 11 for subjecting lactic acid oligomers to a depolymerization reaction; a catalyst regeneration device 27 for subjecting a residue in the depolymerization device to a depolymerization reaction in order to reduce the molecular weights of lactic acid oligomers contained in the residue; and a distillation column 29 for condensing lactide generated in a gas form as a result of the depolymerization reaction. |
