A method of isolating and recovering an aromatic carbonate, in which a solvent having a solubility parameter of 7 to 10 is added to a solution of the aromatic carbonate in an aromatic hydroxy compound to precipitate the aromatic carbonate in the form of a crystal and the aromatic carbonate is isolated and recovered. According to the present invention, there is provided an advantageous method in which a high-purity aromatic carbonate in the form of a solid can be isolated from a reaction mixture solution obtained by reacting an aromatic hydroxy compound with carbon monoxide and molecular oxygen in the presence of a catalyst. Further, a method of recovering a catalyst and a method of recycling the catalyst are provided. |
