Abstract
A gas-phase isomerization process wherein a feed containing one or more members of the 2,6-DMN isomer triad is selectively isomerized over a lower-acidity, supported, molecular-sieve-based catalyst composition to form essentially thermodynamic equilibrium amounts of the members of the 2,6-triad and reduced amounts of outside-the-triad products.
