Eicosane has little use in the petrochemical industry, as its high flash point makes it an inefficient fuel. Due to its chemical inactivity, n-eicosane (a fully straight-chain structural isomer of eicosane) is part of the paraffin 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 colourless, less dense than water, a non-polar molecule, nearly non-reactive with any other atom or molecule unless combusted, and insoluble. Its non-polar trait means it can only perform weak hydrogen intermolecular bonding (Hydrophobic/Van der Waal's forces) == External links == * [http://physchem.ox.ac.uk/MSDS/EI/eicosane.html Material Safety Data Sheet for Eicosane] * http://www.ars-grin.gov/cgi-bin/duke/chemical.pl?EICOSANE Alkanes Eicosane==Page move== (fron WP:RM) ====Icosane → Eicosane==== * Eicosane is where this page was originally, before someone moved it to Icosane last march. I did a google search for both terms. Icosane came up with 378 results, Eicosane came up with 6780 results. Eicosane is also what it should be if IUPAC nomenclature is followed.

I note that the article's two external links use "eicosane", and that one is currently broken because of the use of "ICOSANE" instead of "EICOSANE" in the URL... —User:Tkinias 06:31, 2 Dec 2004 (UTC) See other meanings of words starting from letter: EEA | EB | EC | ED | EF | EG | EH | EI | EJ | EK | EL | EM | EN | EO | EP | ER | ES | ET | EU | EW | EX | EY | EZ |Words begining with Eicosane: Eicosane Eicosane |
