Being a [[trioxane]], it has the [[molecular formula]] C<sub>3</sub>H<sub>6</sub>O<sub>3</sub> and consists of a six membered ring with three [[carbon]] atoms and three [[oxygen]] atoms. == Uses == In chemistry, it is used as a stable, easily handled source of anhydrous [[formaldehyde]]. In acidic solutions, it decomposes to generate three molecules of formaldehyde. It may also be used in polymerization to form acetal resins, such as [[polyoxymethylene plastic]]. When combined with [[hexamine]] and compressed into solid bars, it is used by the [[military]] and [[camping|outdoorsmen]] as a cooking fuel similar to [[hexamine fuel tablet|Esbit]]. 1,3,5-Trioxane is a [[mortician]]'s restorative chemical that repairs cells and maintains the corpse's contours after postmortem tissue constriction.{{Fact|date=February 2007}} Trioxane is also occasionally known by the synonym trioxin, sometimes mistaken for the fictional [[Trioxin (Return of the Living Dead)|2,4,5-trioxin]]. == Derivatives == The only possible mono-bromo derivative of trioxane is C<sub>3</sub>H<sub>5</sub>BrO<sub>3</sub>. == See also == * [[Formaldehyde]] * [[Paraformaldehyde]] * [[Dioxane]] == References == {{Unreferenced|date=September 2007}} <references/> {{DEFAULTSORT:Trioxane, 1,3,5-}} [[Category:Oxygen heterocycles]] [[Category:Acetals]] [[de:Trioxan]] [[it:1,3,5-triossano]] [[nl:Trioxaan]] [[ja:1,3,5-トリオキサン]] [[pl:Trioksan]]
