Description:
Refined naphthalene is a white volatile crystal with a mild aromatic odor. It is insoluble in water and has a special smell. It is the most important fused ring aromatic hydrocarbon in industry. It can be used to produce phthalic anhydride, dye intermediates, rubber additives and pesticides.
According to different purity, naphthalene can be divided into industrial naphthalene and refined naphthalene. The purity of industrial naphthalene is generally about 96%. After removing impurities and desulfurization, high-purity refined naphthalene can be obtained.
ROSS Chem is a China Refined naphthalene Supplier with high purity and competitive price.
