N-OCTANE Chemical Properties,Uses,Production

Chemical Properties

colourless liquid

Chemical Properties

Octane is a colorless liquid with a gasoline-like odor. The odor threshold is 4 ppm and 48 ppm (New Jersey Fact Sheet).

Uses

n-Octane occurs in petroleum crackingproducts, gasoline, petroleum ether, andpetroleum naphtha. It is used as a solventand in organic synthesis.

Definition

A liquid alkane obtained from the light fraction of crude oil. Octane and its isomers are the principal constituents of gasoline, which is obtained as the refined light fraction from crude oil.

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

Inhalation of concentrated vapor may cause irritation of respiratory tract, depression, and pulmonary edema. Liquid can cause irritation of eyes and (on prolonged contact) irritation and cracking of skin. Ingestion causes irritation of mouth and stomach. Aspiration causes severe lung irritation, rapidly developing pulmonary edema, and central nervous system excitement, followed by depression.

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

Flash Point (°F): 56 ℃; Flammable Limits in Air (%): 1.0-6.5; Fire Extinguishing Agents: Dry chemical, foam, carbon dioxide; Fire Extinguishing Agents Not To Be Used: Water may be ineffective; Special Hazards of Combustion Products: Not pertinent; Behavior in Fire: Vapor is heavier than fire and may travel a considerable distance to a source of ignition and flash back; Ignition Temperature (°F): 428; Electrical Hazard: Class I, Group D; Burning Rate: 6.3 mm/min.

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.

First aid

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility.

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.
