25kg/bag, 520bags/20’fcl, (26MT)Refined Naphthalene is the most important condensed-nuclei aromatics in industry. Its Molecular Formula is C10H8, which is the coal tar's most abundant constituent, and usually it is produced by recycling from distilling coal tar and coke-oven gas or by the secondary purification of industrial naphthalenemp 80-82 °C(lit.) bp 218 °C(lit.) density 0.99 vapor density 4.4 (vs air) vapor pressure 0.03 mm Hg ( 25 °C) refractive index 1.5821 Fp 174 °F storage temp.
