| titleOfInvention | Method for recovering an aqueous alkali metal hydroxide solution of a purified aromatic dihydroxy compound |
| abstract | Disclosed is a high-purity aromatic dihydroxy compound obtained by treating a large amount of waste aromatic polycarbonate resin (for example, information media materials such as CDs that are no longer needed, aromatic polycarbonate resin products such as automobile headlamp lenses, sheets, etc.) at low cost. A method for recovering an aqueous alkali metal hydroxide solution is provided. In a method for depolymerizing a waste aromatic polycarbonate resin and recovering a purified alkali metal hydroxide aqueous solution of an aromatic dihydroxy compound, the waste aromatic polycarbonate resin dissolved in an organic solvent and the alkali metal hydroxide aqueous solution are recovered. And a condensing device for condensing the organic solvent vapor evaporated from the reaction tank, and a process having a storage tank for receiving the condensed organic solvent, the alkali metal of the unpurified aromatic dihydroxy compound after the depolymerization reaction A method for recovering an aqueous alkali metal hydroxide solution of a purified aromatic dihydroxy compound by washing the aqueous hydroxide solution with an organic solvent obtained by condensing vapor evaporated from a reaction vessel.
