Description of key information

The phototransformation half-life in air was found by Taylor et al. (1992) to be between 87.2 and 50.2 days in the temperature range from 295 to 339 K and with a OH-radical concentration of 5x10-5/cm3. This result was supported by the AOPWIN estimation model (half-life: 46.78 days with 12h- day and 1.5E6 OH/cm3 at 25°C).
