Abstract
A process for producing an alkyl-substituted aromatic hydrocarbon, which comprises alkylating an aromatic hydrocarbon with an alkylating agent in the presence of a heteropoly-acid or a salt thereof such as phosphorus tungstate and silicon tungstate as a catalyst. The process is particularly useful for preparing alkyl-substituted naphthalene or naphthalene derivatives.
