PRODUCTION OF POLYPHENOL

摘要

PROBLEM TO BE SOLVED: To provide a method capable of arbitrarily changing the constitution ratio of a phenylene unit containing a hydroxyl group constituting a polyphenol and an oxyphenylene unit containing a C-O bond in a method for producing the polyphenol. SOLUTION: In an oxidative polymerization of a phenol using an enzyme as a catalyst, the constitution ratio of a hydroxyl group-containing phenylene unit and an oxyphenylene unit as constituent units of formed polyphenol is controlled by changing the mixing ratio of an organic solvent and water as a reaction solvent.
