Applicant's summary and conclusion
- Conclusions:
- According to EPI (Estimation Programs Interface) Suite OVERALL OH Rate Constant of triethyl phosphite is estimated as 57.9428 E-12 (0.0000000000579428) cm3/molecule-sec .
- Executive summary:
Hydrogen Abstraction = 57.9428 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 = 57.9428 E-12 cm3/molecule-sec
HALF-LIFE = 0.185 Days (12-hr day; 1.5E6 OH/cm3)
HALF-LIFE = 2.215 Hrs
