product description
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 naphthalene.
-------------------------------------------------------------------------------------------------------
physichochemical property
the 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 point
is 217.9 and the relative density is 1.145.
