Title:
METHOD FOR HYDROLYZING NYLON
Document Type and Number:
WIPO Patent Application WO/2023/167314
Kind Code:
A1
Abstract:
This method for hydrolyzing nylon involves monomerizing nylon using nylon hydrolase, and comprises: a step for dissolving nylon in an organic solvent in which nylon is soluble so as to prepare a nylon solution; a step for preparing a nylon precipitation liquid by adding the nylon solution to a precipitating solvent for precipitating nylon in the form of particles; a step for removing the organic solvent and the precipitating solvent from the nylon precipitation liquid; a step for adding an aqueous solution so as to prepare a nylon dispersion liquid; and a step for adding nylon hydrolase to the nylon dispersion liquid so as to hydrolyze the nylon.
