The selectivity for ring-opening of methylnaphthalenes was studied with existence of a NiO-MoO_3/Al_2O_3 at temperatures ranging from 390 to 450℃. Ring-opening proceeded by α-scission of tetrahydro-ring and produced (1-methylbutyl) benzene, pentylbenzene via 1-methyltetralin, 1-butyl-2-methylbenzene, 1-butyl-3-methylbenzene via 5-methyl-tetralin, (2-methylbutyl) benzene, (3-methylbutyl) benzene via 2-methyltetralin and 1-butyl-3-methylbenzene, 1-butyl-4-methylbenzene via 6-methyltetralin. 1-butyl-3-methylbenzene from 1-methylnaphthalene was obtained in highest yield among these products.
