Abstract
A process for producing 4-hydroxydiphenyl ether, characterized by reacting diphenyl ether with an acylating agent in the presence of an acid catalyst to yield a 4-acyldiphenyl ether represented by the formula (1): (wherein R represents (un)substituted alkyl or aryl), reacting the 4-acyldiphenyl ether with a peroxide to yield 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.
