Photoageing of polyolefins. II: Photolysis of low molecular weight ketones at λ > 300 nm

The photolysis of low molecular weight ketones (4-tridecanone, 3- and 5-dodecanone) at wavelengths longer than 300 nm and in hydrocarbon solvents has been investigated by FTIR, GC/MS and GC/FTIR. The quantum yield and the rate of decomposition were compared with those of a low molecular weight hydro...

Zusammenfassung:The photolysis of low molecular weight ketones (4-tridecanone, 3- and 5-dodecanone) at wavelengths longer than 300 nm and in hydrocarbon solvents has been investigated by FTIR, GC/MS and GC/FTIR. The quantum yield and the rate of decomposition were compared with those of a low molecular weight hydroperoxide (3-hydroperoxyhexane).
