Heptanal is a flammable, slightly volatile colorless liquid of pervasive fruity to oily-greasy odor, [7] which is miscible with alcohols [6] and practically insoluble in water. [8] Because of its sensitivity to oxidation, heptanal is filled under nitrogen and stabilized with 100 ppm hydroquinone. [9] Heptanal forms flammable vapor-air mixtures.

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).

It is pyrolyzed to the methyl ester of 10-undecenoic acid and heptanal, which is then air-oxidized to the carboxylic acid. Approximately 20,000 tons were consumed in Europe and US in 1980. [2] Laboratory preparations of enanthic acid include permanganate oxidation of heptanal [3] and 1-octene. [4]

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.
2-Heptanol is a chemical compound which is an isomer of heptanol.It is a secondary alcohol with the hydroxyl on the second carbon of the straight seven-carbon chain. The compound is flammable and irritant, and through inhalation, ingestion or though skin it can enter into the body.
