An oil used for illuminating purposes, formerly obtained from the distillation of mineral wax, bituminous shale, etc., and hence called also coal oil. 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.…

A liquid consisting mainly of the lighter and more volatile hydrocarbons of petroleum or kerosene oil, used as a solvent and for cleansing soiled fabrics; -- called also petroleum spirit, petroleum benzine. Varieties or similar products are gasoline, naphtha, rhigolene, ligroin, etc.

flash, on the approach of a flame, used as a test of the comparative safety of oils, esp. kerosene; a flashing point of 100º F. is regarded as a fairly safe standard. The burning point of the oil is usually from ten to thirty degree above the flashing point of its vapor.

ydrocarbon, C16H34, of the paraffin series, found dissolved as an important ingredient of kerosene, and so called because each molecule has sixteen atoms of carbon; -- called also hexadecane.

An appliance for the destruction of insects, consisting of a shallow iron box, containing kerosene or coated with tar or other sticky substance, which may be mounted on wheels.

mized spray or the vapor (produced by heat) of a comparatively heavy oil, as petroleum or kerosene. In all of these the gas is mixed with a definite amount of air, the charge is composed in the cylinder and is then exploded either by a flame of gas (flame ignition -- now little used), by a hot tube (tube ignition) or t…

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 special lamps.

ne, ethane; intermediate members are liquids, as hexane, heptane, etc. (found in benzine, kerosene, etc.); while the highest members are white, waxy, or fatty solids, as paraffin proper.

in the molecule. Normal nonane is a colorless volatile liquid, an ingredient of ordinary kerosene.

stance, whether solid, liquid, or gaseous, of the same chemical series; thus coal gas and kerosene consist largely of paraffins.

nce, composition, and properties. It is refined by distillation, and the products include kerosene, benzine, gasoline, paraffin, etc. Petroleum spirit, a volatile liquid obtained in the distillation of crude petroleum at a temperature of 170° Fahr., or below. The term is rather loosely applied to a considerable range o…

A light hydrocarbon oil resembling kerosene. It is obtained by distilling coal, paraffin, etc., and is used as a lubricant, illuminant, etc. [Written also photogene.]

H28, of the methane series, which is a probable ingredient both of crude petroleum and of kerosene, and is produced artificially as a light colorless liquid.
