91-20-3 - Application:

Naphthalene (CAS: 91-20-3), the simplest of the fused or condensed ring hydrocarbon compounds composed of two benzene rings sharing two adjacent carbon atoms. Naphthalene is the most abundant single constituent of coal tar, a volatile product from the destructive distillation of coal, and is also formed in modern processes for the high-temperature cracking (breaking up of large molecules) of petroleum.
Naphthalene is a polycyclic aromatic hydrocarbon consisting of two fused benzene rings. Possible carcinogen. Naphthalene is a commercially important aromatic hydrocarbon.
Naphthalene volatilises and sublimes at room temperature above the melting point. For the basic chemical raw materials, the primary use for Naphthalene is in the production of phthalic anhydride, various naphthol, naphthylamine, etc., is the production of synthetic resin, plasticizer, rubber antioxidant, surfactant, synthetic fiber, dye intermediates, coating, pesticides, pharmaceuticals, insecticides, spices, rubber chemicals, and to make other chemicals, and other raw materials. Naphthalene is also used in mothballs. Naphthalene is also used in the manufacture of phthalic and anthranilic acids to make indigo, indanthrene, and etc. Naphthalene is also used in dusting powders, lavatory deodorant discs, wood preservatives, fungicide.
In addition to oxidation and reduction reactions, Naphthalene readily undergoes substitutionreactions such as nitration, halogenation, sulfonation, and acylation to produce a varietyof other substances.
