Icosane (alternative spelling eicosane and eichosane[2]) is an alkane with the chemical formula C20H42. It has 366,319 constitutional isomers.
n-Icosane (the straight-chain structural isomer of icosane) is the shortest compound found in paraffin waxes used to form candles. It can be isolated from Agave attenuate leaves. It is also found in Vanilla madagascariensis and Gymnodinium nagasakiense.[3]
Icosane's size, state or chemical inactivity does not exclude it from the traits its smaller alkane counterparts have. It is a colorless or white, non-polar molecule, nearly unreactive except when it burns. It is less dense than and insoluble in water. Its non-polar trait means it can only perform weak intermolecular bonding (hydrophobic/van der Waals forces).
Icosane's phase transition at a moderate temperature makes it a candidate phase change material, or PCM which can be used to store thermal energy and control temperature.
It can be detected in the body odor of persons suffering from Parkinson's disease.[4]
Naming
IUPAC currently recommends icosane,[5] whereas Chemical Abstracts Service and Beilstein use eicosane.[6]
