実験手順

For example, in the case where 1,5-dimethyltetraline and/or 1,6-dimethyltetraline are/is reacted in a gas phase using a platinum-alumina catalyst to obtain 1,5-dimethylnaphthalene and/or 1,6-dimethylnaphthalene can be prepared efficiently by setting up the catalyst calcination temperature to 300° to 400° C., the catalyst reduction temperature to 400° to 500° C., and the reaction temperature to 350° to 450° C.; or the catalyst calcination temperature to 400° to 500° C., the catalyst reduction temperature to 300° to 400° C., and the reaction temperature to 350° to 450° C.
