Record 4 1999-04-26

English

Subject field(s)
  • Petrochemistry
  • Climate Change
CONT

[The] photochemical oxidants are produced in the atmosphere through a series of complex, interrelated reactions between NOx and reactive hydrocarbons in the presence of sunlight.... The reactivity of a particular hydrocarbon is measured by its effects on the rate of ozone formation in sunlight in the presence of NOx and air. Highly reactive organic compounds include olefins and aldehydes whereas, for example, methane, ethane, and benzene have small or negligible reactivities.
