Additional information

The experimental determined reaction rate constant for the reaction of acetophenone with OH radicals in the gas-phase is reported to be 2.74 x 10E-12 cm³/molecule x s. Taking into account a OH radical concentration of 5 x 10E5 radicals/cm³ (24 h day) a tropospheric half-life t1/2=5.86 d can be calculated. Acetophenone is resistant to hydrolysis under environmental conditions.
