Synthesis of 2,6-dimethylnaphthalene from pentenes and toluene

We report a new technology of more efficiently synthesizing 2,6-dimethylnaphthalene (2,6-DMN) by using pentenes and toluene as low cost feedstocks. The output of 2,6-DMN is maximized and a new technical breakthrough has been made by developing new chemistry with zeolite-based catalysts via a novel hydroisomerization-dehydrogenation sequence.
