It is used in [[jet fuel]]s, [[gasoline]]s, and [[avgas]]. It is a clear liquid with melting point 21-23 °C and boiling point 248-249 °C. It is also used in printing industry. It is stable in acidic, neutral, and alkaline solutions, and is considered to not be readily [[biodegradable]]. It does not absorb [[UV light]], therefore direct [[photodegradation]] is not suspected. One of its trade names is '''Topanol A'''. It is found in antioxidant mixtures AO-30, AO-31, AO-32, IONOL K72, IONOL K78, IONOL K98, and others. It is a suspected respiratory toxicant and is suspected to be [[neurotoxic]]. ==See also== *[[2,6-Di-tert-butylphenol]] *[[Butylated hydroxytoluene]] [[Category:Antioxidants|Dimethyl-6-tert-butylphenol, 2,4-]] [[Category:Phenols|Dimethyl-6-tert-butylphenol, 2,4-]] [[Category:Fuel antioxidants|Dimethyl-6-tert-butylphenol, 2,4-]]
