METHOD OF MAKING DIMENTHYLNAPHTHALENES

摘要

THE METHOD OF THE INVENTION INCLUDES MAKING DIMETHYLNAPTHALENES BY FIRST CONTACTING, IN AN ALKYLATION ZONE, AT ALKYLATION CONDITIONS, A TOLUENE-CONTAINING STREAM WITH A PENTENE-CONTAINING STREAM IN THE PRESENCE OF AND ACID ALKYLATION CATALYST. AT LEAST A PORTION OF THE TOLUENE AND PENTENES REACT TO FORM PENTYTOLUENES. AT LEAST A PORTION OF THE PENTYLTOLUENES IN THEN CONTACTING IN A REFORMING ZONE WITH REFORMING CATALYST, AT REFORMING CONDITIONS. AT LEAST A PORTION OF THE PENTYLTOLUENES IS CONVERTED TO DIMETHYLNAPTHALENES.
