naphthazarine
| naphtha | 1. <chemistry> The complex mixture of volatile, liquid, inflammable hydrocarbons, occurring naturally, and usually called crude petroleum, mineral oil, or rock oil. Specifically: That portion of the distillate obtained in the refinement of petroleum which is intermediate between the lighter gasoline and the heavier benzine, and has a specific gravity of about 0.7, used as a solvent for varnishes, as a carburetant, illuminant, etc. 2. <chemistry> One of several volatile inflammable liquids obtained by the distillation of certain carbonaceous materials and resembling the naphtha from petroleum; as, Boghead naphtha, from Boghead coal (obtained at Boghead, Scotland); crude naphtha, or light oil, from coal tar; wood naphtha, from wood, etc. This term was applied by the earlier chemical writers to a number of volatile, strong smelling, inflammable liquids, chiefly belonging to the ethers, as the sulphate, nitrate, or acetate of ethyl. Naphtha vitrioli [NL, naphtha of vitriol. <chemistry> Common ethyl ether; formerly called sulphuric ether. See Ether. Origin: L. Naphtha, Gr, fr.Ar. Nafth, nifth.

| coal tar naphtha | <chemistry> A volatile, very inflammable liquid, contained in the naphtha produced by the destructive distillation of coal, from which it is separated by fractional distillation. The name is sometimes applied also to the impure commercial product or benzole, and also, but rarely, to a similar mixed product of petroleum. The Benzene nucleus or Benzene ring, is a closed chain or ring, consisting of six carbon atoms, each with one hydrogen atom attached, regarded as the type from which the aromatic compounds are derived. Structure: C6H6 Origin: From Benzoin. (06 Aug 1998) |

| naphthalene |
Naphthalene (also known as naphthalin, naphthaline, tar camphor, white tar, albocarbon, or naphthene) is a crystalline white solid hydrocarbon with a typical mothball odor. Naphthalene is volatile, forming a flammable vapor. Its molecules consist of two fused benzene rings. It is manufactured from coal tar, and converted to phthalic anhydride for the manufacture of plastics, dyes and solvents. It is also used as an antiseptic and insecticide, especially in mothballs. ...
