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: 2066205 9105751 PCTABS00005 The selective alkylation of naphthalene or 2-ethylnaphthalene to diethylnaphthalene while maximizing the yield of the 2,6-diethylnaphthalene isomer is achieved by carrying out the reaction in the presence of a shape selective catalyst such as the zeolite catalyst ZSM-12.

Abstract: The selective isopropylation of a naphthyl compound to diisopropylnaphthalene enhanced in the 2,6diisopropylnaphthalene 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.ANG. to 7.0.ANG.. 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.
