Results and discussion

Dissipation half-life of parent compound
DT50:
19.892 h
Test condition:
half-life calculated for the following conditions: sensitizer for indirect photolysis: OH; 0.5 E06 OH/cm³, 24h day; as the substance is a tertiary amine, the estimate is highly uncertain.

Any other information on results incl. tables

Estimate refers to the uncharged molecule.

Hydrogen Abstraction      = 19.3573 E-12 cm3/molecule-sec

Reaction with N, S and -OH = 0.0000 E-12 cm3/molecule-sec

Addition to Triple Bonds  =  0.0000 E-12 cm3/molecule-sec

Addition to Olefinic Bonds =  0.0000 E-12 cm3/molecule-sec

Addition to Aromatic Rings =  0.0000 E-12 cm3/molecule-sec

Addition to Fused Rings   =  0.0000 E-12 cm3/molecule-sec

 

OVERALL OH Rate Constant = 19.3573 E-12 cm3/molecule-sec

HALF-LIFE =    0.829 Days (24 -hr day; 0.5E6 OH/cm3)

HALF-LIFE =    19.892 Hrs
