N-OCTANE Chemical Properties,Uses,Production
Chemical Properties
colourless liquid
Physical properties
Clear, colorless, flammable liquid with a gasoline-like odor. An odor threshold concentration of 1.7 ppmv was reported by Nagata and Takeuchi (1990).
Uses
n-Octane occurs in petroleum crackingproducts, gasoline, petroleum ether, andpetroleum naphtha. It is used as a solventand in organic synthesis.
Production Methods
Octane is produced from the fractional distillation and refining of petroleum.
Definition
ChEBI: A straight chain alkane composed of 8 carbon atoms.
General Description
Colorless liquid with an odor of gasoline. Less dense than water and insoluble in water. Hence floats on water. Produces irritating vapor.
Air & Water Reactions
Highly flammable. Insoluble in water.
Reactivity Profile
May be incompatible with strong oxidizing agents like nitric acid. Charring may occur followed by ignition of unreacted material and other nearby combustibles. In other settings, mostly unreactive. Not affected by aqueous solutions of acids, alkalis, most oxidizing agents, and most reducing agents. When heated sufficiently or when ignited in the presence of air, oxygen or strong oxidizing agents, burns exothermically to produce mostly carbon dioxide and water.
Health Hazard
The toxic properties of n-octane are similarto those of other paraffinic hydrocarbons. Itis an irritant to mucous membranes, and athigh concentrations it shows narcotic actions.The narcotic concentrations in mice werereported to be 8000–10,000 ppm (Patty andYant 1929) and the fatal concentration was13,500 ppm (Flury and Zernick 1931). Deathoccurred from respiratory arrest. The acutetoxicity of n-octane is somewhat greater thanthat of n-heptane.
Fire Hazard
Behavior in Fire: Vapor is heavier than air and may travel a considerable distance to a source of ignition and flash back.
Chemical Reactivity
Reactivity with Water No reaction; Reactivity with Common Materials: No reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.
Safety Profile
Poison by intravenous route. May act as a simple asphyxiant. See also ARGON for a description of simple asphyxiants. A narcotic in high concentration. Human dermal exposure to undiluted octane for five hours resulted in blister formation but no anesthesia; exposure for one hour caused diffuse burning sensation. A very dangerous fire hazard and severe explosion hazard when exposed to heat, flame, or oxidizers. When heated to decomposition it emits acrid smoke and irritating fumes. See also ALKANES.
Potential Exposure
Octane is used as a solvent; as a fuel; as an intermediate in organic synthesis; and in azeotropicdistillations.
Carcinogenicity
The promoting activity of octane in skin carcinogenesis, including its physical effect on micellar models of biological membranes, was tested. Octane proved to have significant promoting activity when tested as a 75% solution in cyclohexane.
Shipping
UN1262 Octanes, Hazard Class: 3; Labels: 3-Flammable liquid.
Purification Methods
Extract the octane repeatedly with conc H2SO4 or chlorosulfonic acid, then wash it with water, dry and distil it. Alternatively, purify it by azeotropic distillation with EtOH, followed by washing with water to remove the EtOH, drying and distilling it. For further details, see n-heptane. It is also purified by zone melting. [Beilstein 1 H 159, 1 I 60, 1 II 122, 1 III 457, 1 IV 412.]
Incompatibilities
Reacts with strong oxidizers, causing fire and explosion hazard. Attacks some forms of plastics, rubber and coatings.
Waste Disposal
Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an after burner and scrubber. All federal, state, and local environmental regulations must be observed.
