2,4-二枯基酚的合成研究

Preparation of 2,4-Di-(1-phenylisopropyl)phenol

研究以苯酚和α 甲基苯乙烯为原料 ,在酸性催化剂存在下进行芳烷基化反应制取 2 ,4 二枯基酚的工艺 ,以DY1为催化剂 ,在 90℃下反应 3h ,2 ,4 二枯基酚收率 6 2 %以上 ,选择性超过 79%

Synthesis of 2,4 di (1 phenylisopropyl)phenol through aryl alkylation of phenol with α mehtylstyrene in the presence of acid catalyst is studied.With DY1 as catalyst,at 90 ℃,over 3 hours,the yield of 2,4 di(1 phenylisopropyl)phenol is above 62% and the selectivity is above 79%.
