Related to heptane: Nonane


Any of several isomeric, volatile, colorless, highly flammable liquid hydrocarbons, C7H16, obtained in the fractional distillation of petroleum and used as solvents. The straight-chain isomer is also used as a standard in determining octane ratings and as an anesthetic.


(Elements & Compounds) an alkane existing in nine isomeric forms, esp the isomer with a straight chain of carbon atoms (n-heptane), which is found in petroleum and used as an anaesthetic. Formula: C7H16
[C19: from hepta- + -ane, so called because it has seven carbon atoms]


(ˈhɛp teɪn)

any of nine isomeric hydrocarbons, C7H16, of the alkane series, some of which are obtained from petroleum: used in fuels, as solvents, and as chemical intermediates.
