titleOfInvention | Method for obtaining alkaline aqueous solution of aromatic dihydroxy compound from waste aromatic polycarbonate resin |
abstract | PROBLEM TO BE SOLVED: To provide a method for obtaining an alkaline aqueous solution of a high-purity aromatic dihydroxy compound by treating a large amount of waste aromatic polycarbonate (for example, aromatic polycarbonate products such as CD, CD-ROM, DVD, etc. that are no longer needed) at a low cost. To do. In a method for obtaining an alkaline aqueous solution of an aromatic dihydroxy compound by dissolving a waste aromatic polycarbonate resin in an organic solvent and decomposing the polycarbonate resin in the organic solvent solution in the presence of an aqueous alkali metal hydroxide solution. A method for obtaining an alkaline aqueous solution of a purified aromatic dihydroxy compound, which comprises contacting an aqueous alkali solution after decomposition with activated carbon.
