A method for producing 4-hydroxydiphenyl ether,
characterized by reacting diphenyl ether with an acylating agent in the presence of an acid catalyst to obtain a 4-acyldiphenyl ether represented by the formula (1):
wherein R represents a substituted or unsubstituted alkyl or aryl group,
reacting the 4-acyldiphenyl ether with a peroxide to obtain a 4-acyloxydiphenyl ether represented by the formula (2):
wherein R has the same meaning as defined above, and solvolyzing the ester bond of the 4-acyloxydiphenyl ether, is provided.
