Theory and Practice of Alkyl Phenol Synthesis. tert-Octylphenols

Liquid-phase alkylation of phenol with diisobutylenes was studied in the presence of ion-exchange resin Amberlyst 36 Dry. Thermodynamic characteristics were calculated for the reactions that occur in a reaction system. Kinetics of the alkylation process was studied. The conditions of selective synthesis were recommended for 4-tert-octylphenol. Recommendations on the use of obtained data were given.
