ile liquid, condensed by cold and pressure from the first products of the distillation of petroleum; -- used for producing low temperatures.

One of the hexane paraffins, found in petroleum, consisting of two propyl radicals. See Hexane.

C20H42, of the paraffine series, of artificial production, and also probably occurring in petroleum.

One of the higher hydrocarbons of the paraffin series, C11H24, found as a constituent of petroleum. [Written also hendecane.]

A highly volatile mixture of fluid hydrocarbons, obtained from petroleum, as also by the distillation of bituminous coal. It is used in making air gas, and in giving illuminating power to water gas. See Carburetor.

A kind of internal-combustion engine; -- in British countries called usually petrol engine.

ecule has seven carbon atoms. Specifically, a colorless liquid, found as a constituent of petroleum, in the tar oil of cannel coal, etc.

ydrocarbon burner, furnace, stove, a burner, furnace, or stove with which liquid fuel, as petroleum, is used.

That which illuminates or affords light; as, gas and petroleum are illuminants. Boyle.

ne boiler. The gas used may be a fixed gas, or one derived from alcohol, ether, gasoline (petrol), naphtha, oil (petroleum), etc. There are three main classes: (1) gas engines proper, using fixed gases, as coal, blast-furnace, or producer gas; (2) engines using the vapor of a volatile fluid, as the typical gasoline (pe…

It is now produced in immense quantities, chiefly by the distillation and purification of petroleum. It consists chiefly of several hydrocarbons of the methane series.

applied somewhat indefinitely to some of the volatile products obtained in refining crude petroleum. It is a complex and variable mixture of several hydrocarbons, generally boils below 170º Fahr., and is more inflammable than safe kerosene. It is used as a solvent, as a carburetant for air gas, and for illumination in…

ganic objects, as distinguished from plants or animals. -- Mineral oil. See Naphtha, and Petroleum. -- Mineral paint, a pigment made chiefly of some natural mineral substance, as red or yellow iron ocher. -- Mineral patch. See Bitumen, and Asphalt. -- Mineral right, the right of taking minerals from land. -- Miner…

from 0.05 to 0.1 per cent of aluminium is added to lower the melting point, usually in a petroleum furnace, keeping the molten metal at the bubbling point until it becomes quiet, and then pouring the molten metal into a mold lined with a special mixture consisting essentially of molasses and ground burnt fire clay; al…

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 ab…

A peculiar hydrocarbon occuring as an ingredient of Caucasian petroleum.

methane series. The most important is a colorless, volatile, inflammable liquid, found in petroleum, and a constituent of benzene or ligroin.

A colorless liquid hydrocarbon of the octylene series, occurring in Caucasian petroleum.

nce, resembling spermaceti, tasteless and odorless, and obtained from coal tar, wood tar, petroleum, etc., by distillation. It is used as an illuminant and lubricant. It is very inert, not being acted upon by most of the strong chemical reagents. It was formerly regarded as a definite compound, but is now known to be a…

A hydrocarbon of the paraffin series, (C15H32) found in petroleum, tar oil, etc., and obtained as a colorless liquid; -- so called from the fifteen carbon atoms in the molecule.
