摘　　要：以4-叔丁基苯酚和苯乙烯为原料,Keggin型杂多酸12-磷钨酸为催化剂,合成4-叔丁基-2-(α-甲基苄基)苯酚(t-BAMBP),考察了原料摩尔比、反应时间、反应温度以及催化剂用量对t-BAMBP收率的影响。结果表明,较优工艺条件为:n(苯乙烯)∶n(4-叔丁基苯酚)=1.3∶1,反应时间为90 min,反应温度为90℃,催化剂用量为1%[m(12-磷钨酸)∶m(4-叔丁基苯酚)],4-丁基苯酚转化率为95%,t-BAMBP收率为62.4%。The 4-tert-butyl-2-（α-methyl benzyl）phenol（t-BAMBP） was synthesized with 4-tert-butylphenol and styrene as raw materials,Keggin-type 12-phosphotungstic acid as catalyst.The effect of ratio of reactants,reaction time and temperature,catalyst dosage on yield of t-BAMBP were studied.The optimal conditions were as follows：n（styrene） ∶ n（4-tert-butyl-phenol）=1.3 ∶ 1,reaction time was 90 min,reaction temperature was 90 ℃ and the catalyst dosage was 1%[m（12-phosphotungstic acid） ∶ m（4-tert-butylphenol）].Under the optimum conditions,the conversion of 4-tert-butylphenol and the yied of t-BAMBP could reach 95% and 62.4%,respectively.
