Sulfurous acid H2SO3 - and it does exist

World's first proof under atmospheric conditions calls textbook opinion into question

05-Sep-2024 - Once again, the atmosphere amazes us with its diverse chemical processes. For the first time, researchers at the Leibniz Institute for Tropospheric Research (TROPOS) in Leipzig have demonstrated the existence of sulfurous acid (H2SO3) under atmospheric conditions in the gas phase. The results ...

New class of substances detected in atmospheric chemistry

International team reports on highly oxidized hydrotrioxides

31-May-2022 - An international research team has now succeeded in detecting hydrotrioxides (ROOOH) for the first time under atmospheric conditions. Until now, there was only speculation that these organic compounds with the unusual OOOH group exist. In laboratory experiments, their formation during the ...

Oxidation processes in combustion engines and in the atmosphere take the same routes

25-Feb-2021 - Alkanes, an important component of fuels for combustion engines and an important class of urban trace gases, react via another reaction pathways than previously thought. These hydrocarbons, formerly called paraffins, thus produce large amounts of highly oxygenated compounds that can contribute to ...

Rapid pair production: Detection of a new reaction path in the atmosphere

04-Apr-2018 - Scientists have now observed a particularly rapid type of pair production in the laboratory: Hydrocarbons double when two peroxyl radicals react with each other. This means that stable products with the carbon skeleton of both peroxyl radicals are formed, which very likely will have a peroxide ...
