α-甲基苯乙烯与苯酚的烷基化反应研究

Study on the Aryl-alkylation of Phenol with α-Methylstyrene

分别以磷酸-冰醋酸,苯酚铝,阳离子型交换树脂及络合物为催化剂,研究了α-甲基苯乙烯与苯酚的烷基化反应。用GC测得各组份的含量,结果表明,用不同的催化剂,可生成不同含量的烷基化产物。烷基化产物以4-枯基苯酚,2,4-二枯基苯酚及2,4,6-三枯基苯酚为主。

The aryl-alkylation of α-methylstyrene with phenol in the presence of various strong acid catalysts were studied. The contents of 4-cumylphenol, 2,4-dicumylphenol and 2,4,6-tricumylphenol were obtained by GC. The different contents of various alkylation products were obtained with different catalysts.
