Heptane, a colorless and clear liquid, is known for its specific odor. It falls under various classifications for hazardous materials, including "Hazardous Substance Class 1, Petroleum No. 1, Hazardous Rank II" under the Fire Service Act and is recognized under several regulations for its handling and transportation due to its hazardous nature.
As a solvent, heptane (n-heptane) is utilized in polyolefin polymerization, adhesives, paints, inks, and for extracting oils and fats. It also serves as a thinner, a measuring reagent in spectroscopic and gas chromatography analyses, and in determining the octane number of gasoline. Its role as a cleaning agent in research experiments highlights its versatility in scientific applications.
n-Heptane is characterized by a melting point of -91°C, a boiling point of 98°C, a flash point of -1°C, and a spontaneous combustion point of 204°C. Known for its volatility and petroleum odor, n-heptane's solubility in ethanol and diethyl ether contrasts with its insolubility in water. Its CAS registration number is 142-82-5.
Heptane has 11 isomers, including n-heptane, which is a linear alkane with the chemical formula CH3(CH2)5CH3 and a molecular weight of 100.20. Notably, n-heptane is used as an indicator of octane number 0.
n-Heptane, distinguished by having seven carbon atoms in its main chain, is the only heptane isomer in this category.
2-methylhexane and 3-methylhexane, both with six carbon atoms in the main chain, represent this category. 2-methylhexane is also known as isoheptane.
3-ethylpentane, with one side chain, and four types with two side chains—2,2-dimethylpentane, 2,3-dimethylpentane, 2,4-dimethylpentane, and 3,3-dimethylpentane—constitute this group. 2,2-dimethylpentane is also referred to as neoheptane.
2,2,3-trimethylbutane is the sole heptane type with four carbon atoms in the main chain and three in the side chains.
Considering stereoisomers, there are 11 for heptane. For instance, 3-methylhexane exists as (3R)-3-methylhexane and (3S)-3-methylhexane, while 2,3-dimethylpentane has (3R)-2,3-dimethylpentane and (3S)-2,3-dimethylpentane. These compounds illustrate the smallest alkanes possessing a chiral carbon.
