Abstract: 2064016 9101286 PCTABS00003 The invention relates to a process for the separation of various dialkyl multinuclear aromatic compounds from a feed stream of mixed isomers of those compounds. A shape selective adsorbent is employed resulting in a process that is more efficient than processes based upon prior separation techniques. Of special interest are combination processes involving synthesis steps followed by sorption steps using the same shape selective materials.

Abstract: A process for the selective manufacture of 2,6-diisopropylnaphthalene from naphthalene advantageously combines an equilibration reactor to enhance the amount of monoisopropylnaphthalene fed to the alkylation reactor, and the use of a shape selective catalyst in the alkylation reactor, to obtain an alkylation reaction product in which the 2,6-diisopropylnaphthalene isomer comprises greater than 39 mole percent of the total diisopropylnaphthalene obtained. Further, this combination of reaction steps and conditions produces a reaction product in which the ratio of 2,6-diisopropylnaphthalene to 2,7-diisopropylnaphthalene is greater than 1.0, preferably greater than 1.2. Recycled process components are fed to the equilibration reactor where they are combined with fresh naphthalene feed to provide a monoisopropylnaphthalene enriched feed to the alkylation reactor.

Abstract: The selective isopropylation of a naphthyl compound to diisopropylnaphthalene enhanced in the 2,6-diisopropylnaphthalene isomer is obtained in the presence of an acidic crystalline molecular sieve catalyst having twelve membered oxygen rings. The catalyst pore aperture dimension ranges from 5.5 ANGSTROM to 7.0 ANGSTROM . The use of these shape selective catalysts results in a diisopropylnaphthalene stream which is enhanced in beta isomers and enhanced in the desired 2,6-diisopropylnaphthalene isomer. A particularly preferred catalyst is synthetic Mordenite. Specific catalyst modifications are also described to improve selectivity to the desired 2,6-diisopropylnaphthalene isomer.
