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.
