Naphtha vitrioli

[NL., naphtha of vitriol] (Old Chem.), common ethyl ether; — formerly called sulphuric ether. See Ether.

Naphthalate
(Naph"tha*late) n. (Chem.) A salt of naphthalic acid; a phthalate. [Obs.]

Naphthalene
(Naph"tha*lene) n. (Chem.) 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.

Naphthalene red (Chem.), a dyestuff obtained from certain diazo derivatives of naphthylamine, and called also magdala red. — Naphthalene yellow (Chem.), a yellow dyestuff obtained from certain nitro derivatives of naphthol.

Naphthalenic
(Naph`tha*len"ic) a. (Chem.) 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
(Naph*tha"lic) a. (Chem.) (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. (b) Formerly, designating an acid probably identical with phthalic acid.

Naphthalidine
(Naph*thal"i*dine) n. [Naphthalene + toluidine.] (Chem.) Same as Naphthylamine.

Naphthalin
(Naph"tha*lin Naph"tha*line) n. [F. naphthaline.] (Chem.) See Naphthalene.

Naphthalize
(Naph"tha*lize) v. t. (Chem.) To mingle, saturate, or impregnate, with naphtha.

Naphthazarin
(Naph*thaz"a*rin) n. [Naphthalene + alizarin.] (Chem.) A dyestuff, resembling alizarin, obtained from naphthoquinone as a red crystalline substance with a bright green, metallic luster; — called also naphthalizarin.

Naphthene
(Naph"thene) n. (Chem.) A peculiar hydrocarbon occuring as an ingredient of Caucasian petroleum.

Naphthide
(Naph"thide) n. (Chem.) A compound of naphthalene or its radical with a metallic element; as, mercuric naphthide.

Naphthoic
(Naph*tho"ic) a. (Chem.) Pertaining to, derived from, or related to, naphthalene; — used specifically to designate any one of a series of carboxyl derivatives, called naphthoic acids.

Naphthol
(Naph"thol) n. [Naphthalene + -ol.] (Chem.) Any one of a series of hydroxyl derivatives of naphthalene, analogous to phenol. In general they are crystalline substances with a phenol (carbolic) odor.

Naphthol blue, Naphthol orange, Naphthol yellow (Chem.), brilliant dyestuffs produced from certain complex nitrogenous derivatives of naphthol or naphthoquinone.

Naphthoquinone
(Naph`tho*qui"none) n. [Naphthalene + quinone.] (Chem.) A yellow crystalline substance, C₁₀H₆O₂, analogous to quinone, obtained by oxidizing naphthalene with chromic acid.

Naphthyl
(Naph"thyl) n. [Naphthalene + -yl.] (Chem.) A hydrocarbon radical regarded as the essential residue of naphthalene.

Naphthylamine
(Naph`thyl*am"ine) n. (Chem.) One of two basic amido derivatives of naphthalene, C₁₀H₇.NH₂, forming crystalline solids.
