| titleOfInvention | Method for regenerating reaction solvent, reaction solvent and aqueous urethane resin dispersion |
| abstract | An object of the present invention is to provide a method for regenerating a reaction solvent capable of recovering a reaction solvent from an aqueous urethane resin dispersion and regenerating the reaction solvent to a high-purity one containing almost no basic reaction initiator or water. The present invention relates to a reaction for recovering and regenerating a reaction solvent from an aqueous urethane resin dispersion obtained by dispersing a polymerized urethane resin in water by allowing a basic reaction initiator to be present in the reaction solvent. A method for regenerating a solvent, wherein a recovery step of evaporating and recovering a reaction solvent from the dispersion, and adding an acid to the recovered reaction solvent, the basic reaction contained in the recovered reaction solvent A neutralization step of neutralizing and immobilizing the initiator, and a distillation step of distilling the reaction solvent having passed through the neutralization step to distill the reaction solvent and remove water contained in the reaction solvent, And a membrane separation step of separating and removing water contained in the distilled reaction solvent by a gas separation membrane.
