Synthesis of 4-octyl phenol byphenol and octyl alcohol with sulfonic acid resin
4-Octyl phenol is synthesized by phenol and octyl alcohol with sulfonic acid resin as catalyst. Using single factor experimental method,the optimum conditions are obtained as follows: reaction temperature is 135-140 ℃,reaction time is about 20 h,the amount of catalyst is about 0. 2 of phenol amount,the mole ratio of phenol to octyl alcohol is 1 ∶1. 2. Under the mentioned condition,the conversion can reach 80% and the selectivity can reach 80%.
