Abstract
Dialkylnaphthalenes, especially 2,6-dialkylnaphthalene can be prepared with good yield for a long time by reacting naphthalene and/or monoalkylnaphthalenes with C.sub.2 -C.sub.4 olefin in the presence of silica-alumina catalyst containing 0.1-15 weight percent of fluorine under suitable conditions.
