Heptane Chemical Properties,Uses,Production

Chemical Properties

colourless liquid

Chemical Properties

n-Heptane is a flammable liquid, present in crude oil and widely used in the auto- mobile industry. For example, as a solvent, as a gasoline knock testing standard, as automotive starter fl uid, and paraffi nic naphtha. n-Heptane causes adverse health effects in occupational workers, such as CNS depression, skin irritation, and pain. Other compounds such as n-octane (CH 3 (CH 2 ) 6 CH 3 ), n-nonane (CH 3 (CH 2 ) 7 CH 3 ), and n-decane (CH 3 (CH 2 ) 8 CH 3 ) have different industrial applications. Occupational workers exposed to these compounds also show adverse health effects. In principle, manage- ment of these aliphatic compounds requires proper handling and disposal to avoid health problems and to maintain chemical safety standards for safety to workers and the living environment.

Chemical Properties

n-Heptane is a clear liquid which is highly flammable and volatile with a mild, gasoline-like odor. The odor threshold is 40 547 ppm; also reported @ 230 ppm.

Uses

Suitable for HPLC, spectrophotometry, environmental testing

Uses

heptane is a solvent and viscosity-decreasing agent.

Uses

As standard in testing knock of gasoline engines.

Definition

A colorless liquid alkane obtained from petroleum refining. It is used as a solvent.

Definition

heptane: A liquid straight-chainalkane obtained from petroleum,C7H16; r.d. 0.684; m.p. -90.6°C; b.p.98.4°C. In standardizing octanenumbers, heptane is given a valuezero.

General Description

Highly flammable. Insoluble in water.

Reactivity Profile

HEPTANE is incompatible with the following: Strong oxidizers .

Hazard

Toxic by inhalation. Flammable, dangerous fire risk.

Health Hazard

VAPOR: Not irritating to eyes, nose or throat. If inhaled, will cause coughing or difficult breathing. LIQUID: Irritating to skin and eyes. If swallowed, will cause nausea or vomiting.

Fire Hazard

FLAMMABLE. Flashback along vapor trail may occur. Vapor may explode if ignited in an enclosed area.

Fire Hazard

Flash Point (°F): 25 ℃; Flammable Limits in Air (%): 1.0 - 7.0; Fire Extinguishing Agents: Foam, dry chemical, or carbon dioxide; Fire Extinguishing Agents Not To Be Used: Not pertinent; Special Hazards of Combustion Products: Not pertinent; Behavior in Fire: Not pertinent; Ignition Temperature (°F): 433; Electrical Hazard: Class I, Group D; Burning Rate: 6.8 mm/min.

Chemical Reactivity

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.

Potential Exposure

n-Heptane is used in graphics, textiles, adhesives, and coatings; as an industrial solvent and in the petroleum refining process; as a standard in testing knock of gasoline engines.

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, includ ing resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medi cal attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.

Shipping

UN1206 Heptanes, Hazard Class: 3; Labels: 3-Flammable liquid.

Incompatibilities

May form explosive mixture with air. Strong oxidizers may cause fire and explosions. Attacks some plastics, rubber and coatings. May accumulate static electric charges that can ignite its vapors.

Waste Disposal

Dissolve or mix the material with a combustible solvent and burn in a chemical incinera tor equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.
