Icosane (also known by the name eicosane or as didecyl) is an alkane with the chemical formula C20H42. It has 366,319 constitutional isomers.
Icosane has little use in the petrochemical industry, as its high flash point makes it an inefficient fuel. Due to its chemical inactivity, n-icosane (the straight-chain structural isomer of icosane) is part of the paraffin group, and is the shortest molecule in the compounds used to form candles.
Icosane's size, state or chemical inactivity does not exclude it from the traits its smaller alkane counterparts have. It is a colorless, less dense than water, non-polar molecule, nearly non-reactive unless combusted, 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.
Naming
IUPAC currently recommends icosane, whereas Chemical Abstracts Service and Beilstein use eicosane.
