|Section2= }} Trioxidane (also systematically named μ-trioxidanediidodihydrogen), also called hydrogen trioxide or dihydrogen trioxide, is an inorganic compound with the chemical formula (also written as or ). It is one of the unstable hydrogen polyoxides. In aqueous solutions, trioxidane decomposes to form water and singlet oxygen: :400px The reverse reaction, the addition of singlet oxygen to water, typically does not occur in part due to the scarcity of singlet oxygen. In biological systems, however, ozone is known to be generated from singlet oxygen, and the presumed mechanism is an antibody-catalyzed production of trioxidane from singlet oxygen. ==Preparation== Trioxidane can be obtained in small, but detectable, amounts in reactions of ozone and hydrogen peroxide, or by the electrical dissociation of water. Larger quantities have been prepared by the reaction of ozone with organic reducing agents at low temperatures in a variety of organic solvents such as the anthraquinone process, and it is also formed during the decomposition of organic hydrotrioxides (ROOOH). The reaction of ozone with hydrogen peroxide is known as the "peroxone process". This mixture has been used for some time for treating groundwater contaminated with organic compounds. The reaction produces H2O3 and H2O5. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「trioxidane」の詳細全文を読む スポンサード リンク
