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 ).
In chemistry, an alcohol (from Arabic al-kuḥl 'the kohl'), [2] is a type of organic compound that carries at least one hydroxyl (−OH) functional group bound to a saturated carbon atom. [ 3 ] [ 4 ] Alcohols range from the simple, like methanol and ethanol , to complex, like sugars and cholesterol .
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.
1-Heptanol is an alcohol with a seven carbon chain and the structural formula of CH 3 (CH 2) 6 OH. [1] It is a clear colorless liquid that is very slightly soluble in water, but miscible with ether and ethanol .
For this reason, measured viscosities of the noble gases serve as important tests of the kinetic-molecular theory of transport processes in gases (see Chapman–Enskog theory). One of the key predictions of the theory is the following relationship between viscosity μ {\displaystyle \mu } , thermal conductivity k {\displaystyle k} , and ...

Heptanol may refer to any isomeric alcohols with the formula C 7 H 16 O: . 1-Heptanol, an alcohol with a seven carbon chain and the structural formula of CH 3 (CH 2) 6 OH; 2-Heptanol, a secondary alcohol with the hydroxyl on the second carbon of the straight seven-carbon chain
The formation of heptanal in the fractional distillation of castor oil [3] was already described in 1878. The large-scale production is based on the pyrolytic cleavage of ricinoleic acid [4] (Arkema method) and on the hydroformylation of 1-hexene with rhodium 2-ethylhexanoate as a catalyst upon addition of some 2-ethylhexanoic acid (Oxea method): [2] [5]
