Study shows alkanes can rapidly acquire oxygen atoms in a free radical chain reaction; significant for fuel combustion and air pollution
An international team of researchers has shown that alkanes participate extensively in autoxidation reactions with oxygen molecules. The discovery, which overturns current chemical wisdom, has implications for air quality prediction and efficient fuel combustion in engines. An open-access paper on the work is published in the journal
Communications Chemistry.
Oxidation chemistry controls both combustion processes and the atmospheric transformation of volatile emissions. In combustion engines, radical species undergo isomerization reactions that allow fast addition of O
2. This chain reaction, termed autoxidation, is enabled by high engine temperatures, but has recently been also identified as an important source for highly oxygenated species in the atmosphere, forming organic aerosol.
