It is widely approved to prevent [[gumming]] in [[aviation fuel]]s. It is a clear to pale yellow semi-solid, with melting point between 34-36 °C and boiling point at 253 °C, insoluble in water but soluble in [[ether]] and [[methanol]]. It is also used in manufacture of fragrances and pharmaceuticals. The ast majority of its production volume is used as an intermediate for synthesis of other substances, mostly other phenolic antioxidants. It is not readily [[biodegradable]], and is very toxic to water organisms. [http://www.inchem.org/documents/sids/sids/128392.pdf] Its trade names include '''Ethanox 701''', '''Ethyl 701''', '''Ethyl AN 701''', '''Irganox L 140''', '''Isonox 103''', and '''TK 12891'''. ==See also== *[[2,4-Dimethyl-6-tert-butylphenol]] *[[butylated hydroxytoluene]] ==References== {{Unreferenced|date =September 2007}} <references/> {{DEFAULTSORT:Di-tert-butylphenol, 2,6-}} [[Category:Antioxidants]] [[Category:Phenols]] [[Category:Fuel antioxidants]]
