Abstract
A method of preparing alkylnaphthalene compounds by reaction of a compound of naphthalene or monoalkylnaphthalene with olefin in the presence of a heteropoly acid catalyst. The method enables to produce highly valuable 2-monosubstituted alkylnaphthalene compounds or 2,6-disubstituted alkylnaphthalene compounds, in a high selectivity and a high yield. The used catalyst may be readily recovered and re-utilized.
