Dihydrogentrioxid ( H2O3 ) is in addition to water (H2O ) and hydrogen peroxide (H2O2 ), a further oxygen compound of hydrogen.

It can be produced by the anthraquinone process, but instead of normal oxygen, ozone is used. It is an unstable substance and decomposes above -40 ° C. In nature it may be an intermediate product of reaction.

Reactions

Wasserstofftrioxid spontaneously breaks water molecules H2O and molecular oxygen O2. In organic solutions, however, the half-life is 16 minutes in the presence of water only a few milliseconds, since the polar influence curves lying in the trans position of the chain oxygen atoms and so the proton can easily switch to the other end.

Studies show that Wasserstofftrioxid causes the known antibacterial action of the mixture of ozone and hydrogen peroxide. Ibid is also believed that this is used by immune cells in biological systems, where the antibody generate said molecular oxygen, which is formed partially Wasserstofftrioxid ( in appropriate concentration ) in the exchange reaction. The Wasserstofftrioxid then acts as a strong oxidizing agent.

In 2005 Dihydrogentrioxid could be observed by means of molecular spectroscopy. It was shown that the chain in trans configuration with an oxygen-oxygen bond length of 142.8 picometer ( compare 146.4 picometer hydrogen peroxide ) is present. Calculations of theoretical chemistry also predict longer Oxide Chains, a class of Hydrogenpolyoxiden, however, can exist only at very low temperatures, such as in space.
