Heptanoic acid, also called enanthic acid, is an organic compound composed of a seven-carbon chain terminating in a carboxylic acid. It is an oily liquid with an unpleasant, rancid odor.[1] It contributes to the odor of some rancid oils. It is slightly soluble in water, but very soluble in ethanol and ether.
Heptanoic acid is used in the preparation of esters, such as ethyl heptanoate, which are used in fragrances and as artificial flavors.
It is also one of many additives in cigarettes.
Heptanoic acid can be used to synthesize pure hexane, which is the main chemical component of gasoline.[2] Concentrated hydrochloric acid can be used to catalyze the decarboxylation reaction:
C7H14O2 + HCl + (Heat) -> C6H14 + CO2 + HCl
OR:
H3C-CH2-CH2-CH2-CH2-CH2-COOH + HCl(aq) + (Heat) -> H3C-CH2-CH2-CH2-CH2-CH3 + CO2 + HCl
Heptanoic acid is known to exist in Mimosa.
Finding plant sources that contain high levels of this fatty acid and Hexanoic acid would be helpful in solving energy/fuel crisis problems. Hexanoic acid and Heptanoic acid can be used to synthesize pentane and hexane, both of which have lower boiling points than Octane and Heptane. Because of their low boiling points, they burn cleaner in combustion engines and give better mileage than high octane fuels.[3]
