1. A process for enriching the fraction of 2,6-diisopropylnaphthalene contained in a feed stream of mixed diisopropylnaphthalenes comprising contacting said feed stream with an adsorbant bed containing one or more crystalline molecular sieves being characterized as having twelve membered oxygen rings and pore aperture dimensions between approximately 5.5 Å

  • and 7.0 Å and

    which demonstrate shape selective preference for 2,6-diisopropylnaphthalene over other dialkylated naphthalenes, separating said feed stream from said adsorbant bed and contacting the adsorbant bed with a desorbant capable of substantially desorbing said 2,6-diisopropylnaphthalene from the pores of said crystalline molecular sieves.
