Autoignition =Eicosane (also known by the
IUPAC name icosane or as didecyl) is analkane hydrocarbon with thechemical formula C20H42. It has 366,319constitutional isomer s.Eicosane has little use in the
petrochemical industry, as its highflash point makes it an inefficient fuel. Due to its chemical inactivity, "n"-eicosane (the straight-chain structuralisomer of eicosane) is part of theparaffin group, and is the shortest molecule in the compounds used to form candles.Eicosane'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 hydrogenintermolecular bonding (hydrophobic /van der Waals force s).Eicosane'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.References
