Chlorotrifluoroethylene Decay in the Atmosphere: Controlled-Environment Chamber Studies
Abstract
This report documents a series of experiments conducted to shed additional light on the role of surface-catalyzed reactions on the potential atmospheric oxidation of CTFE vapor. The experiments were conducted in a controlled-environment chamber consisting of a one-meter diameter stainless steel sphere which is Teflon coated. Vapor-phase CTFE was introduced into the chamber at the 5-10 ppm concentration level. It was exposed to helium, then helium with 20 percent oxygen, then helium with 20-50 ppm ozone added, and to humid (approx. 75 percent R.H.) helium, both with and without oxygen. After these initial experiments were concluded, 20 corroded aluminum plates were added to the chamber which increased its surface area by about a factor of ten. Then CTFE was introduced with dry helium, helium plus oxygen, and helium plus ozone.. .. CTFE, Controlled-environment chamber, FT-IR Spectroscopy, Surface-catalyzed reactions.
