Phototransformation in air

Model prediction

Using AOP Program (v1.92) of EPISuite software the aerobic degradation was assessed. The overall OH rate constant was calculated to be 126.0750 E-12 cm3/molecule-sec and the half-life was calculated to be 1.018 h. The substance is not within the applicability domain of the model and the estimated values are highly uncertain. Nevertheless, taking the criteria of the FOCUS air report (2006) into account it was concluded that after evaporation or exposure to the air, the substance will be rapidly degraded by photochemical processes.

Hydrolysis

According to column 2 of Regulation (EC) 1907/2006, Annex VIII,section 9.2.2.1 a study on hydrolysis does not need to be conducted as the substance is readily biodegradable.

Furthermore according to Kollig et al. (1993), Boethling & Mackay (2000) and Harris (1990), the test substance is generally resistant to hydrolysis because it does not contain any labile functional groups. Therefore, no study on hydrolysis is performed.
