Description of key information

After evaporation or exposure to the air, the product will be rapidly degraded by photochemical processes with OH-radicals.

Key value for chemical safety assessment

Additional information

Based on a measured rate constant of 3.35E-11 cm³/molecules*sec methyl vinyl ether is indirectly photodegraded by reaction with hydroxyl radicals in the atmosphere with a half-life (t1/2) of about 11.5 hours taking into account a 24-h day and a mean OH radical concentration of 5.0E+05 molecules per cm³ (Atkinson 1979).
