Specific details on test material used for the study:

Iodobis(triphenylphosphino)copper (Bruggolen® H3301), batch no. 16101213
Production date 12. Oct. 2016
Expiry date 12. Oct. 2026

Key result

Decomposition:

yes

Decomp. temp.:

ca. 415.27 °C

No clear boiling point could be determined under these circumstances only an exothermic phase could be detected as the third event with:

415.27± 0.30 °C (688.42 ± 0.30 K)

Decomposition was indicated by a weak exothermic peak and the changed appearance of the sample in the crucible after the DSC measurement. Observations of the pre-test confirm this, as well.

Conclusions:

The boiling point of Iodobis(triphenylphospino)copper was determined via DSC (differential scanning calorimetry)
No clear boiling point could be determined under these circumstances only an exothermic phase could be detected as the third event with:
415.27± 0.30 °C (688.42 ± 0.30 K)
Decomposition was indicated by a weak exothermic peak and the changed appearance of the sample in the crucible after the DSC measurement. Observations of the pre-test confirm this, as well.
The first event was identified as solid to solid transition with:
143.01 ± 0.19 °C (416.16 ± 0.19 K)
The second event was identified as melting point with:
177.45 ± 0.17 °C (450.60 ± 0.17 K)
 
No observations were made which might cause doubts on the validity of the study outcome. Therefore, the result of the study is considered valid.

Executive summary:

The boiling point of Iodobis(triphenylphospino)copper was determined via DSC (differential scanning calorimetry)

 

No clear boiling point could be determined under these circumstances only an exothermic phase could be detected as the third event with:

 

415.27± 0.30 °C (688.42 ± 0.30 K)

This value is the mean of two independent determinations.
