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.
NAPH'THA, n. [L. Gr. Ch. Syr. and Ar. from نَفَطَ nafata, to push out, as pustules, to throw out, to boil, to be angry. In Amharic, neft or nepht, from this sense, signifies a gun or musket.]
A volatile limpid bituminous liquid, of a strong peculiar odor, and generally of a light yellow color; but it may be rendered colorless by careful distillation. It is very inflammable, and burns with a white flame, mixed with much smoke. It is insoluble in water, but unites in every proportion with absolute alcohol. Turner. By long keeping it hardens into a substance resembling vegetable resin, and becomes black.
Naphtha exsudes from the earth in Persia, and, as is said, in the neighborhood of Babylon. Naphtha may be obtained by the distillation of asphalt from the Dead Sea, and of petroleum from Trinidad.
Naphtha consists of carbon and hydrogen, in equal equivalents. Thomson.
- 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,
- 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.
