Abstract:
PCT No. PCT/FI97/00095 Sec. 371 Date Sep. 15, 1998 Sec. 102(e) Date Sep. 15, 1998 PCT Filed Feb. 14, 1997 PCT Pub. No. WO97/30012 PCT Pub. Date Aug. 21, 1997The invention concerns a preparation process for 2,6-dimethylnaphthalene in which 1-(p-tolyl)-2-methylbutane and/or 1-(p-tolyl)-2-methylbutene are dehydrocyclisized using a reduced vanadium catalyst. 2,6-dimethylnaphthalene can be used as starting material when manufacturing polyethylenenaphthalate. The conversion of this method is good and the selectivity of 2,6-dimethylnaphthalene can be improved by reducing the catalyst.
