Kerosene Usage And Synthesis
Kerosene is a white to pale yellow, mobile flammable, and combustible liquid. Kerosene (hydrodesulfurized) is a complex combination of hydrocarbons obtained from a petroleum stock by treating with hydrogen to convert organic sulfur to hydrogen sulfide, which is removed. Kerosene generally consists of hydrocarbons having carbon numbers predominantly in the range of C9 through C16 and boiling in the range of approximately 150–290℃ （302–554°F).
Usually used to store alkali metals and prevent air re-dissolution.
In kerosene lamps, flares, and stoves; as degreaser and cleaner; Deobase formerly used as a solvent in cosmetics and in fly spray.
Kerosene is produced by direct fractionation of the “middle distillate fraction”. Individual kerosene composition varies widely, but consists mainly of linear and branched aliphatics, olefins, cycloparaffins, and aromatics in the C10–C16 range. For indoor heating fuels it is desirable to remove the olefins, aromatics, and sulfur compounds, because they promote the evolution of soot and sulfur oxides. For some purposes, highly refined or “deodorized” kerosene is manufactured by treatment with activated charcoal or by clay filtration and is generally less toxic than untreated kerosene.
A clear colorless to light amber liquid with a petroleum odor. Flash point 100°F. Less dense than water and insoluble in water. Vapors are heavier than air.
Air & Water Reactions
Highly flammable. Insoluble in water.
Saturated aliphatic hydrocarbons, contained in Kerosene, may be incompatible with strong oxidizing agents like nitric acid. Charring of the hydrocarbon may occur followed by ignition of unreacted hydrocarbon and other nearby combustibles. In other settings, aliphatic saturated hydrocarbons are mostly unreactive. They are not affected by aqueous solutions of acids, alkalis, most oxidizing agents, and most reducing agents.
Moderate fire risk, explosive limits in air 0.7–5.0%. Toxic by inhalation. Questionable carcinogen.
Vapor causes slight irritation of eyes and nose. Liquid irritates stomach; if taken into lungs, causes coughing, distress, and rapidly developing pulmonary edema.
Reactivity with Water No reaction; Reactivity with Common Materials: No reactions; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.
Stir it with conc H2SO4 until a fresh portion of acid remains colourless, then wash with water, dry with solid KOH and distil it in a Claisen flask. For more complete drying, the kerosene can be refluxed with Na, and distilled from Na.
