摘要：
A method for preparing a dialkylnaphthalene in one step by contacting an dialkylbenzene compound with a solid catalyst in a gas or liquid phase in the presence of hydrogen, using a catalyst having composition (I) or (II) below:(1)(M.sup.1).sub.a.(M.sup.2).sub.b.(SiO.sub.2.XAl.sub.2 O.sub.3).(Al.sub.2 O.sub.3).sub.c (I)(2) Mixture of II-(i) and II-(ii):(M.sup.3).sub.d.(Al.sub.2 O.sub.3) II-(i)(M.sup.4).sub.e.(SiO.sub.2.XAl.sub.2 O.sub.3) II-(ii)wherein M.sup.1 is a metal selected from the group consisting of metals belonging to group VIII of a periodic table and rhenium;M.sup.2 is a member selected from the group consisting of zinc, gallium, and oxides thereof;M.sup.3 is a metal belonging to group VIII of a periodic table;M.sup.4 is at least one alkali metal; anda, b, c, d, e, and X represent proportions, respectively.
