| Abstract: | The p-t-butylcatechol (4-TBC) was synthesized from catechol and isobutylene using a new catalyst. Effect of process conditions on reaction was investigated. The optimum technology parameters were obtained the yield of 4-TBC was above 93%when the reaction temperature was 125℃,reaction time was 2 h,the mole ratio of catechol to isobutylene was 1 ∶ 0.65,and the catalyst amaunt was 0.1%. |
