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 ).

This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
Heptene is a higher olefin, or alkene with the formula C 7 H 14. The commercial product is a liquid that is a mixture of isomers. It is used as an additive in lubricants, as a catalyst, and as a surfactant. This chemical is also known as heptylene.
The boiling point of 89.7 °C is 0.3 °C higher than the value of 89.4 °C predicted by Wiener's formula, based on the structure of the molecule and the boiling point of n-heptane. [ 2 ] [ 3 ] The speed of sound at 3 MHz is 1149.5 m/s at 20 °C and 889.5 m/s at 80 °C.
2,2,4-Trimethylpentane, also known as isooctane or iso-octane, is an organic compound with the formula (CH 3) 3 CCH 2 CH(CH 3) 2.It is one of several isomers of octane (C 8 H 18).This particular isomer is the standard 100 point on the octane rating scale (the zero point is n-heptane).
Norbornane (also known as bicyclo[2.2.1]heptane) is an organic compound and a saturated hydrocarbon with chemical formula C 7 H 12. It is a crystalline compound with a melting point of 88 °C . The carbon skeleton is derived from cyclohexane ring with a methylene bridge in the 1,4- position, and is a bridged bicyclic compound.
Norcarane, or bicyclo[4.1.0]heptane, is a colorless liquid. It is an organic compound prepared using the Simmons–Smith reaction , by the action of diiodomethane and a zinc-copper couple on cyclohexene in diethyl ether .
