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
