Results and discussion

Water solubility
Key result
Remarks on result:
not determinable

Any other information on results incl. tables

Due to rapid degradation/reaction in contact with oxygen, it was not possible to develop and validate an analytical method for test item. Test item degrades in water-medium due to oxygen present forming a complex mixture of degradation products for which a sensitive and accurate analytical method could not be developed. Due to rapid degradation/reaction in contact with oxygen water solubility could also not be determined for Tri-n-butyl phosphine.

Applicant's summary and conclusion

Conclusions:
Test item oxidizes in water.
Executive summary:

Due to rapid degradation/reaction in contact with oxygen water solubility could also not be determined for Tri-n-butyl phosphine.
