| titleOfInvention | Distillation method and carbonic acid diester production method |
| abstract | Disclosed is a distillation method for distillate containing a plurality of components having different boiling points and high melting points. A distillate containing an unreacted aromatic monohydroxy compound is distilled off from a reaction solution obtained in a step of synthesizing a carbonic acid diester using an aromatic monohydroxy compound and a carbonyl compound as raw materials. Is introduced into the heat exchanger 16a operating at a temperature below the melting point of the aromatic monohydroxy compound, and a part of the condensate L is further circulated upstream of the heat exchanger 16a.
