A process for enriching the fraction of 2,6-diisopropylnaphthalene contained in a quantity of mixed dialkylated naphthalenes. The mixed dialkylated naphthalenes are contacted with an adsorbant bed containing one or more molecular sieves which demonstrate shape selective preference for the 2,6-diisopropylnaphthalene isomer over other dialkylated naphthalenes. The adsorbant bed is then contacted with a desorbant capable of desorbing the 2,6-diisopropylnaphthalene from the pores of the adsorbant. |
