8008-20-6 Usage


Kerosene is primarily derived from refined petroleum. Kerosene was discovered in 1853 by Abraham Gesner, a British physician, through an extraction process of inflammable liquid from asphalt, a waxy petroleum mixture. Kerosene, therefore, is often called coal or fuel oil because of its asphalt origins. Kerosene was the first material to be chemically extracted on a large commercial scale.

Chemical Properties

Different sources of media describe the Chemical Properties of 8008-20-6 differently. You can refer to the following data:
1. 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).
2. yellow liquid


Different sources of media describe the Uses of 8008-20-6 differently. You can refer to the following data:
1. Usually used to store alkali metals and prevent air re-dissolution.
2. In kerosene lamps, flares, and stoves; as degreaser and cleaner; Deobase formerly used as a solvent in cosmetics and in fly spray.
3. Kerosene, originally used for lighting and heating, is also used as a diesel fuel, as a component in blending aviation fuels, as a solvent and carrier for a wide range of products (including cleaning compositions and pesticides), and as a mold-release agent in the ceramic and pottery industry.

Production Methods

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.

General Description

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.

Reactivity Profile

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.

Flammability and Explosibility


Environmental Fate

Kerosene is composed of aliphatic hydrocarbons with 10–16 carbons per molecule and benzene and naphthalene derivatives. Because kerosene is a complex mixture of various hydrocarbon fractions, its transport and transformation in the environment are dependent on the environment fate of the individual hydrocarbons that comprise it. Kerosene can enter the environment because of its uses – engine fuels, domestic heating, pesticide, and solvent. Environmental releases of kerosene predominantly results in portioning to air. The halflife reaction is calculated to be 0.27–2.2 days. Photodegeneration is rapid in the air phase. Kerosene is expected to have low mobility and some immobility when released to soil. Volatilization does occur. Kerosene is biodegradable in soil, although some components of the mixture adhere strongly to the soil. Kerosene is also biodegradable in surface water. However, some components of the mixture may bioconcentrate in fish and other aquatic organisms. Hydrolysis is insignificant because kerosene lacks the functional groups that hydrolyze under environmental conditions.

Purification Methods

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.

Toxicity evaluation

The specific mechanism of toxicity of kerosene has not been completely determined. The primary risk from ingestion of kerosene is aspiration during emesis, which may cause pneumonitis. The biochemical mechanism of lung response to large concentrations of aerosolized kerosene (resulting in bronchoconstriction and asthma-like symptoms) may involve the parasympathetic nervous system via a direct effect on the vagus nerve or by inhibition of acety1cholinesterase. The mechanism(s) of central nervous system (CNS) depression from kerosene exposure has not been elucidated, but undoubtedly includes disruption of the membranes of nerve cells.

Check Digit Verification of cas no

The CAS Registry Mumber 8008-20-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 8,0,0 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 8008-20:
76 % 10 = 6
So 8008-20-6 is a valid CAS Registry Number.
