Results and discussion
Any other information on results incl. tables
Photochemical reaction of o-chloronitrobenzene in air free from nitrogen oxides
- irradiation results in chloronitrophenols (2-chloro-6-nitrophenol and 2-chloro-4-nitrophenol)
- the reaction never produced the directly hydroxylated derivatives
Photochemical reaction of o-chloronitrobenzene in nitrogen free from nitrogen oxides
- irradiation results in chlorophenols (o-Chlorophenol)
- the nitro group in the test compound was converted to the hydroxyl group
For both tests, in air free from nitrogen oxides as well as in nitrogen free from nitrogen oxides the rate of disappearance of o-Chloronitrobenzene was significantly higher in quartz vessels than in glass vessels.
Rate of disappearance of o-Chloronitrobenzene:
- air free from nitrogen oxides / glass vessel: 4.3 %
- air free from nitrogen oxides / quartz vessel: 66 %
- nitrogen free from nitrogen oxides / glass vessel: 9.5 %
- nitrogen free from nitrogen oxides / quartz vessel: 93%
Applicant's summary and conclusion
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.
