Title: METHOD FOR RECOVERING DECOMPOSITION PRODUCT OF THERMOSETTING RESIN CURED PRODUCT AND METHOD FOR PRODUCING REGENERATED MATERIAL
Abstract:
Provided is a method for recovering a decomposition product of a thermosetting resin cured product, which comprises: a step wherein an object to be processed containing a thermosetting resin cured product is brought into contact with a processing liquid that contains an alkali metal compound and an alcohol solvent, thereby decomposing and dissolving the thermosetting resin cured product; a step wherein an acidic aqueous solution and the processing liquid, in which a decomposition product of the thermosetting resin cured product is dissolved, are mixed with each other, thereby separating the mixture into an aqueous layer and an organic layer that contains the decomposition product; and a step wherein the organic layer is recovered.
