METHOD OF MAKING DIMETHYLNAPHTHALENES

摘要

The method of the invention includes making dimethylnaphthalenes by first contacting, in an alkylation zone, at alkylation conditions, a toluenecontaining stream with a pentene-containing stream in the presence of an acid alkylation catalyst. At least a portion of the toluene and pentenes react to form pentyltoluenes. At least a portion of the pentyltoluenes is then contacting in a reforming zone with reforming catalyst, at reforming conditions. At least a portion of the pentyltoluenes is converted to dimethylnaphthalenes.
