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.
Physical properties	Clear, colorless, very flammable liquid with a faint, pleasant odor resembling hexane or octane. Based on a triangle bag odor method, an odor threshold concentration of 670 ppb_v was reported by Nagata and Takeuchi (1990).
Uses	Suitable for HPLC, spectrophotometry, environmental testing
Uses	As standard in testing knock of gasoline engines.
Uses	heptane is a solvent and viscosity-decreasing agent.
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.
Production Methods	Heptane is produced in refining processes. Highly purified heptane is produced by adsorption of commercial heptane on molecular sieves.
Synthesis Reference(s)	Tetrahedron Letters, 3, p. 43, 1962 DOI: 10.1007/BF01499754
General Description	Clear colorless liquids with a petroleum-like odor. Flash point 25°F. Less dense than water and insoluble in water. Vapors heavier than air.
Air & Water Reactions	Highly flammable. Insoluble in water.
Reactivity Profile	HEPTANE is incompatible with the following: Strong oxidizers .
