ABSTRACT:
An improved process for the continuous alkylation of phenol with olefins having 6 to 12 carbon atoms in the liquid phase and in the presence of strongly acid ion exchange resin catalysts mounted in a fixed bed. The phenol and olefins are passed in a first stage at temperatures from about 80.degree. to 120.degree. C. over an ion exchange resin catalyst having an exchange capacity of from 50 to 96 m Val per 100 ml of catalyst and then passed in a second stage at temperatures about 110.degree. to 130.degree. C. over another ion exchange resin catalyst having an exchange capacity of from 100 to 180 m Val per 100 ml of catalyst.
