What is Heptane

Heptane is frequently used as a test fuel component in anti-knock tests for engines, among several other applications. Heptane is available in a variety of isomers and is sometimes referred to as Septane.One of the most common uses of heptane is in laboratory tests as a non-polar solvent to determine the presence of organic compounds. It works for transport and storage in its liquid form, and in a grease spot test, it is used to dissolve a spot of oil, showing the previous presence of organic compounds on the stained paper. All it takes is a shake of the stained paper in a heptane solution for around a half a minute.

  • Coatings and construction:It is used as a paint thinner.
  • Rubber: The vulcanization of rubber utilizes heptane as a compounder. In the commercial manufacture of rubber cement, unvulcanized rubber is placed in a solvent of 70-90% heptane. Different grades of rubber cement are created depending on a higher or lower percentage of heptane within the solvent.
  • Pharmaceutical: N-heptane for research and development and pharmaceutical manufacturing.

Quick Answers

Heptane or n-heptane is the straight-chain alkane with the chemical formula H₃C(CH₂)₅CH₃ or C₇H₁₆, and is one of the main components of gasoline. When used as a test fuel component in anti-knock test engines, a 100% heptane fuel is the zero point of the octane rating scale.
