Industrially important benzylphenol has been synthesized by alkylation of phenol with benzyl alcohol in the presence of p-toluenesulphonic acid as catalyst under several reaction conditions. The effects of different reaction parameters; such as temperature, molar ratio of phenol to benzyl alcohol and amount of p-toluenesulphonic acid were investigated to optimize the reaction conditions. The alkylated product was characterized by different spectroscopic means. Results showed that the percentage yield of alkylation product increased with an increase in temperature, molar ratio of reactants and amount of catalyst.
