ABSTRACT:
A process for separating dimethyl naphthalenes having a component comprising 2,6-dimethyl naphthalene in the form of complexes with a complex-forming compound, which comprises contacting a dimethyl naphthalene isomer mixture comprising at least 2,6-dimethyl naphthalene or a hydrocarbon mixture containing said dimethyl naphthalene isomer mixture with a complex-forming compound selected from the group consisting of nitro compounds of 2,6-naphthalene dicarboxylic acid, trimellitic anhydride and 2-chloro-5-nitrobenzoic acid, thereby to form a mixture of complexes of the dimethyl naphthalenes with said complex-forming compound having a main component comprising a complex of 2,6-dimethyl naphthalene with the complex-forming compound, and separating the complexes in the solid state from the reaction mixture.
