Product DescriptionRefined Naphthalene is the most important condensed-nuclei aromatics in industry. Its Molecular Formula is C10H8, Which is the coal tar's most abundant constituent, andusually it is produced by recycling from distilling coal tar and coke-oven gas or by thesecondary purification of industrial naphthalene. Physichochemical PropertyThe Refined Naphthalene is white crystal, and sublimation. It has gentle aromatic smell,water insoluble, dissolving in ethanol, ethyl ether, chloroform, carbon tetrachloride,benzene and carbon disulfide. 100% Content pure naphthalene has following properties:vapor pressure is 0.13kPa/52.6, flash point is 80, melting point is 80.2, the boiling pointis 217.9 and the relative density is 1.145.
