EC number: 201-052-9
CAS number: 77-73-6
Author reports a recommended rate constant
of 119 E-12 cm3 molecule-1sec-1. Half
life is calculated based on this rate constant and a hydroxyl radical
concentration of 1.5 E+6 molecule.cm-3
Overall OH rate constant = 119.1993 E-12 cm3/molecule-sec
Half-life = 0.090 days (12-h day; 1.5E6 OH/cm3)
Half-life = 1.077 h
Overall ozone rate constant = 40.000000 E-17
Half-life = 0.029 days (at 7 E+11 mol/cm3)
Half-life = 41.256 min
Measured data from author and other
investigators were quality assessed and then used to develop rate
constants for different chemicals. Therefore, this value represents a
valid rate constant based on all valid studies at the time of
The prediction is considered to fall within
the model domain.
Atmospheric photooxidation half-life of 1.077 hours (hydroxyl radicals) has been reported.
Atkinson (1985), measured data from author and other investigators were
quality assessed and then used to develop rate constants for different
chemicals. Therefore, this value represents a valid rate constant based
on all valid studies at the time of publication. The estimated half life
is 1.077 hours based on an overall OH rate constant of 119.1993 E-12 cm³
