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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Results and discussion
Water solubility
- Remarks on result:
- other: Phosgene decomposes rapidly in water.
- Details on results:
- Phosgene decomposes rapidly in water, and therefore no accurate estimates of water solubility
can be experimentally derived.
Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information): decomposes
Phosgene readily reacts with water and hydrolyzes very rapidly. Data from numerous handbooks
report that phosgene hydrolyzes rapidly in aqueous solutions to carbon dioxide and hydrochloric
acid. The half-life in water has been estimated at 0.026 seconds (Manogue and Pigford, 1960),
which precludes accurate estimates of water solubility.
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.
