Abstract:2,4-Dimethyl-6-tert-butylphenol was prepared from 2,4-dimethylphenol and isobutylene and in the presence of the catalyst sulfuric acid. The structure of the compound was characterized by gas chromatograph,nuclear magnetic resonance spectrum and mass spectrum and infrared spectrum. The influencing factors such as the quantity of isobutylene and reaction time on yield were discussed. And a series of experiments showed that the method had good repetitiveness and stability. The purity of target product was 99% with yield up to 95%.
Key words:2,4-dimethylphenol;isobutylene;alkylation;2,4-dimethyl-6-tert-butylphenol
