Phototransformation in air

Calculations were performed with AOPWIN v1.92 (EPI Suite, 2008). In reaction with hydroxyl radicals, the half-life of the substance was found to be 0.175 days (2.097 hours) at 25°C with 12h-day and 1.5 x 106OH.cm-3. The overall OH rate constant was 61.21 x 10-12cm3/molecule -sec. In reaction with ozone, the half-life of the substance is 0.336 days (8.060 hours) at 25°C and 7x 1011mol/cm3. The overall ozone rate constant is 3.412500 x 10-17cm3/molecule-sec.

Hydrolysis

The hydrolysis of the test substance was tested according to EU Method C7. The main test was conducted at 25°C at pH 7 and pH9. DT 50 values were established respectively at 13860 hrs and 219.30 hrs at pH 7 and 9.
