摘　　要：采用大孔HUSY沸石催化2-甲基萘与异丙醇反应合成2-甲基-6-异丙基萘,HUSY的活性较好,2,6-位产品选择性较高。结合间硝基甲苯法和低碳醇重结晶法对产物进行分离提纯,获得了2-甲基-6-异丙基萘纯品;采用气-质联用,1H、13C及多种二维核磁共振方法,表征了2-甲基-6-异丙基萘的结构,并用gCOSY、gHSQC、gHMBC等技术完成了1H1、3C NMR谱带的归属,首次给出了该化合物的化学位移数据。2-Methyl-6-isopropylnaphthalene was synthesized through the alkylation of 2-methylnaphthalene with isopropanol in the presence of HUSY zeolite, an active and selective catalyst for 2, 6-isomer. The product was then purified by the eutectic crystallization and solvent crystallization processes. The molecular structure of 2-methyl-6-isopropylnaphthalene was elucidated by mass spectrometry, ^1H,^13C and several 2D NMR techniques （gCOSY, gHSQC, gHMBC）, respectively. The ^1H and ^13C NMR chemical shifts of 2-methyl-6-isopropylnaphthalene were assigned.
