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..

Naphtha :: Naphtha (n.) 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..

Naphthalate :: Naphthalate (n.) A salt of naphthalic acid; a phthalate.

Naphthalene :: Naphthalene (n.) A white crystalline aromatic hydrocarbon, C10H8, analogous to benzene, and obtained by the distillation of certain bituminous materials, such as the heavy oil of coal tar. It is the type and basis of a large number of derivatives among organic compounds. Formerly called also naphthaline..

Naphthalenic :: Naphthalenic (a.) Pertaining to , or derived from, naphthalene; -- used specifically to designate a yellow crystalline substance, called naphthalenic acid and also hydroxy quinone, and obtained from certain derivatives of naphthol..

Naphthalic :: Naphthalic (a.) Pertaining to, derived from, or related to, naphthalene; -- used specifically to denote any one of a series of acids derived from naphthalene, and called naphthalene acids..

Naphthalic :: Naphthalic (a.) Formerly, designating an acid probably identical with phthalic acid..

Naphthalidine :: Naphthalidine (n.) Same as Naphthylamine.

Naphthalin :: Naphthalin (n.) Alt. of Naphthalin.

Naphthaline :: Naphthaline (n.) See Naphthalene.

Naphthalize :: Naphthalize (v. t.) To mingle, saturate, or impregnate, with naphtha..

Naphthazarin :: Naphthazarin (n.) A dyestuff, resembling alizarin, obtained from naphthoquinone as a red crystalline substance with a bright green, metallic luster; -- called also naphthalizarin..
