Heptane or n-heptane is the straight-chain alkane with the chemical formula H 3 C(CH 2) 5 CH 3 or C 7 H 16. 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 (the 100 point is 100% iso-octane ).

The Jeffrey pine is noted for producing exceptionally high levels of n-heptane in its resin, for which reason its distillate was designated as the zero point for one octane rating. Floral scents have also long been known to contain volatile alkane components, and n-nonane is a significant component in the scent of some roses. [41]
Maltenes are the n-alkane (pentane or heptane)-soluble molecular components of asphalt, which is the residue remaining after petroleum refiners remove other useful derivatives such as gasoline and kerosene from crude oil. Asphaltene compounds are the other primary component of asphalt.
Cationically crosslinked ECC is used in a variety of industrial applications, due to its low viscosity, excellent electrical properties and high reliability among others as an electrical insulator, as coating and adhesive or as printing ink. [7] Homopolymerized ECC, however, is extremely brittle, which is disadvantageous.
Heptadecane is an organic compound, an alkane hydrocarbon with the chemical formula C 17 H 36.The name may refer to any of 24894 theoretically possible structural isomers, or to a mixture thereof.
2-Methylheptane is a branched-chain alkane and an isomer of octane.It is an heptane molecule with a methyl group attached to its second atom. It is a flammable colorless liquid used as fuel.
The compound is similar in its properties to the simplest triol glycerol, but it is much more viscous at lower density and only about half as hygroscopic as glycerol. Because of its lower polarity and higher molecular volume, 1,2,6-hexanetriol often forms more stable mixtures or emulsions, especially with non-polar components, and is therefore ...
