[0002] Methylnaphthalene is a colorless, oily liquid with a naphthalene-like odor that evaporates with steam. It is flammable, insoluble in water, and soluble in ether and ethanol. Its relative density (20°C) is 1.025, its boiling point is 245°C, and its flash point is 82.2°C. Methylnaphthalene is the primary raw material for the production of disperse dye auxiliaries (dispersants). It can also be used as a heat carrier and solvent, a surfactant, and a sulfur extractant.
