2,4-Di-t-butylphenol was synthesized with phenol and tert-butyl alcohol as raw material and phosphoric acid as cata-lyst. The product of high purity was obtained by purification using the chemical properties of hindered phenol. The factors that had influence on the reaction were investigated. The optimal conditions for this reaction were as follows:the molar ratio of phenol to tert-butyl alcohol was 1∶3,the dosage of catalyst of 85%aqueous phosphoric acid was 10mL,the reaction time and temperature were 5h and 60℃ respectively. The yield of 2,4-di-t-butylphenol under such conditions was about 57. 1%.
