Kinetic study on gas-phase reactions of alkylperoxy radicals withNO2 using chemical conversion method

摘要

Alkylperoxy radicals (RO2) is important for the gas phase oxidation process,i.e.thephotochemical oxidant formation in the troposphere.The sole source of RO2 comes fromthe reaction of hydroxyl radicals (OH) with hydrocarbons.Depends on the structure ofhydrocarbons,a diversity of RO2 can be produced.As for the fate of RO2 in the atmosphere,it reacts primarily with NO or other peroxy radicals (mainly HO2).The reaction with NO2also can occur,however,few relevant researches have been conducted.
