Isolation of ozonides from gas-phase ozonolyses of terpenes

Article Abstract:

The ozonolyses of beta-pinene and sabinane yielded the ozonides 6,6-dimethylbicyclo{3.1.1(super 1,5)}heptane{2-spiro-3}-1,2,4-trioxolane and 5-isopropylbicyclo{3.1.0(super 1,5)}hexane {2-spiro-3}-1,2,4-trioxolane. The identification of the ozonides were made through either long-path Fourier transform infrared spectroscopy or by gas chromatography/mass spectrometer analysis. Results revealed that terpenes are the most predominant compounds detected during gas-phase ozonlyses of olefins.

Determination of ozone removal rates by selected building products using the FLEC emission cell

Article Abstract:

Indoor ozone removal as a product of building materials is studied with a field and laboratory emission cell (FLEC). Ozone removal curves are graphed for carpet, linoleum, parquet, gypsum board, melamine coated particle board, steel, and glass.
