The long-chain alkylation of β-methylnaphthalene with α-dodecene in the presence of Aluminum muriate and over HY zeolite catalyst has been investigated in contrast and the products are analyzed and characterized by gas chromatography and gas chromatography-mass spectrometry. 以气相色谱质谱联用技术为主要分析手段,研究了三氯化铝或HY沸石分子筛催化β甲基萘的长链烷基化,这里以1十二烯烃为烷基化剂。
