Naphthalene Usage And Synthesis
Chemical Propertieswhite to almost white crystals, crystalline flakes
UsageNaphthalene was used in liquid-phase exfoliation of graphite in organic solvents for the production of graphene sheets. It was used in preparation of carbon-coated Si 70 Sn 30 nanoparticles. It was used as fluorescent probe to study the aggregation behavior of sodium cholate. It was used to investigate influence of added short chain linear and branched alcohols on the binding of 1:1 complex of naphthalene and β-cyclodextrin.
Air & Water ReactionsHighly flammable. Insoluble in water.
Reactivity ProfileVigorous reactions, sometimes amounting to explosions, can result from the contact between aromatic hydrocarbons, such as Naphthalene, and strong oxidizing agents. They can react exothermically with bases and with diazo compounds. Substitution at the benzene nucleus occurs by halogenation (acid catalyst), nitration, sulfonation, and the Friedel-Crafts reaction. Naphthalene, camphor, glycerol, or turpentine will react violently with chromic anhydride [Haz. Chem. Data 1967. p 68]. Friedel-Crafts acylation of Naphthalene using benzoyl chloride, catalyzed by AlCl3, must be conducted above the melting point of the mixture, or the reaction may be violent [Clar, E. et al., Tetrahedron, 1974, 30, 3296].
Health HazardFire may produce irritating and/or toxic gases. Contact may cause burns to skin and eyes. Contact with molten substance may cause severe burns to skin and eyes. Runoff from fire control may cause pollution.
Fire HazardFlammable/combustible material. May be ignited by friction, heat, sparks or flames. Some may burn rapidly with flare burning effect. Powders, dusts, shavings, borings, turnings or cuttings may explode or burn with explosive violence. Substance may be transported in a molten form at a temperature that may be above its flash point. May re-ignite after fire is extinguished.
