An international scientific research team successfully proved the existence of hydrogen trioxide (roooh) in atmospheric environment for the first time In the experimental environment, isoprene and α- This special compound will be produced in the oxidation process of pinene (alpha pinene). However, in the atmospheric environment, the existence of these organic compounds with unusual oooh groups is only a guess.
Important data about these new compounds have been calculated by quantum chemical calculation and model calculation. The oxidation of isoprene produces about 10million metric tons in the earth's atmosphere every year. The life of rooohs is estimated to be several minutes to several hours.
Researchers led by Leibniz tropospheric Research Institute (Tropos) wrote in this issue of the famous scientific journal Science that hydrogen trioxide represents a kind of substance in the atmosphere that has not been noticed before, and its impact on health and environment needs to be studied.
In the literature, it has been speculated that there may be substances in the atmosphere that carry not only two oxygen atoms (ROOH), but also three oxygen atoms (roooh). In organic synthesis, hydrogen trioxide is used to form special oxidation products in the reaction with olefins.
However, these reactive and thermally unstable trioxides are produced in organic solvents there at very low temperatures of about -80 ℃ (-112 ℉) and react further. It is not known until now whether such substances also exist as gases in the atmosphere at significantly higher temperatures.
In their research, researchers from the Leibniz tropospheric Institute (Tropos), the University of Copenhagen and the California Institute of Technology (Caltech) have now been able to provide direct evidence for the first time that the reaction of peroxy radical (ro2) and hydroxyl radical (OH) can also form hydrogen trioxide under atmospheric conditions.
