A specific solid base obtained by heat treating alumina and an alkali metal carbonate and/or aluminate and an alkali metal exhibits extremely high alkylation activity, and can efficiently produce target alkyl-substituted aromatics with a small amount of catalyst. It was discovered that hydrocarbons can be produced, and that they can be easily separated from the reaction products, and that the solid base has little risk of ignition even when it comes into contact with air or moisture in the atmosphere, and is extremely easy to handle.
