Preparation of p-1,1,3,3-Tetramethylbutylphenol by Using Nafion-H Catalyst

p-1,1,3,3-Tetramethylbutylphenol was prepared by the alkylation of the phenol with Nafion catalyst in extremely high yield.Various reaction conditions were investigated,including the reaction temperature,reaction time,ratio of the starting material,amount of the Nafion catalyst and the recycle times of the catalyst.
