NAPHTHA

n.[from nafata, to push out, as pustules, to throw out, to boil, to be angry. In Ambaric, neft or nepht, from this sense, signifies a gun or musket. ] 1. An inflammable mineral substance of the bituminous kind, of a light brown or yellowish color, sharp taste, and incapable of decomposition. By long keeping it hardens into a substance resembling vegetable resin, and becomes black. It is as inflammable as ether. It is said to issue from the earth at Baku, in Persia, and to be received into cisterns.
2. Naphtha consists of carbon and hydrogen.

 

NAPHTHALINE

n.A peculiar crystalizable substance, deposited from naphtha distilled from coal tar, consisting of hydrogen and carbon.

2. (Chem. )

 

Defn: 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.

 

Note: 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. Watts. Naphtha vitrioli Etym: [NL. , naphtha of vitriol ] (Old Chem. ), common ethyl ether; -- formerly called sulphuric ether. See Ether.
