Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Phototransformation in air
Administrative data
Link to relevant study record(s)
- Endpoint:
- phototransformation in air
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Acceptable, well documented publication which meets basic scientific principles
- Principles of method if other than guideline:
- Review data with no special reference to the methods used in the experiments
- GLP compliance:
- no
- Estimation method (if used):
- PHOTOCHEMICAL REACTION WITH OH RADICALS
- Concentration of OH radicals: 500000 molecule/cm³
- Temperature for which rate constant was calculated: 298 (±20) Deg K - Light source:
- not specified
- Key result
- % Degr.:
- 50
- Sampling time:
- 3.7 d
- Transformation products:
- not specified
- Validity criteria fulfilled:
- not applicable
- Conclusions:
- The half-life of n-octane, normalized to a 12-hour day, is 3.7 days, based on 12-hour light / 12-hour dark periods and an OH- concentration of 5E5. The half-life is normalized to a 12-hour day because atmospheric oxidation reactions only take place in the presence of sunlight.
- Executive summary:
The half-life of n-octane, normalized to a 12-hour day, is 3.7 days, based on 12-hour light / 12-hour dark periods and anconcentration of 5E5. The half-life is normalized to a 12-hour day because atmospheric oxidation reactions only take place in the presence of sunlight.
Reference
Rate constant cm3 • molecule-1• s-1: 8.72 x 10 -12
The half-life of n-octane, normalized to a 12-hour day, is 3.68 days, based on 12-hour light / 12-hour dark periods and an concentration of 5E5. The half-life is normalized to a 12-hour day because atmospheric oxidation reactions only take place in the presence of sunlight.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
