Carboxylic Acids in Secondary Aerosols from Oxidation of Cyclic Monoterpenes by Ozone

Article Abstract:

Monoterpenes emitted from the forest industry have received little research attention. These biological compounds are oxidized by ozone forming three carboxylic acids and are a secondary organic aerosol in the atmosphere.

Indoor chemistry: ozone and volatile organic compounds found in tobacco smoke

Article Abstract:

A room-sized environmental chamber is filled with environmental tobacco smoke (ETS) and ozone to determine the effect of ozone on certain volatile organic compounds (VOCs). The presence of VOCs in the room with no ozone, moderate ozone, and high ozone is charted.

Gas phase reaction of alkenes with ozone: formation yields of primary carbonyls and biradicals

Article Abstract:

The gas phase reaction of two alkenes namely trans-2,2-dimethyl-3-hexene and 2,4-dimethyl-2-pentene with ozone yielded various carbonyl products. The study, which was conducted at ambient temperature and p=1 atm of air with sufficient cyclohexane added to scavenge the hydroxyl radical, indicated that the formation yields of primary carbonyls are also the formation yields of the corresponding biradicals.
