Zusammenfassung:A process for separating dimethyl naphthalenes the main component of which is 2,6-dimethyl naphthalene in the form of their complexes with m-nitrobenzoic acid, which comprises contacting a dimethyl naphthalene isomer mixture comprising at least 2,6-dimethyl naphthalene or a hydrocarbon mixture containing such dimethyl naphthalene isomer mixture with m-nitrobenzoic acid, to thereby form a mixture of complexes of the dimethyl naphthalenes with m-nitrobenzoic acid the main component of which is a complex of 2,6-dimethyl naphthalene with m-nitrobenzoic acid, and separating the complexes in the solid state from the reaction mixture.
