Results and discussion
Melting / freezing point
- Key result
- Decomposition:
- yes
- Decomp. temp.:
- > 180 °C
- Remarks on result:
- not determinable
- Remarks:
- Since the test item decomposed prior to melting, no melting point could be determined.
Any other information on results incl. tables
The first endotherm at approximately 80 °C is a non-reversible thermal event. It is considered that the test item thermally decomposes from approximately 180 °C to a black residue of copper (II) oxide, which is consistent with the observed mass loss (50 to 58% loss, theoretical mass loss in decomposition of the test item to CuO is 58%).
Applicant's summary and conclusion
- Conclusions:
- The test item was determined to thermally decompose, prior to melting, from approximately 180 °C. Since the test item decomposed prior to melting, no melting point could be determined.
- Executive summary:
Decomposed from approximately 180 °C (453 K) prior to melting, by differential scanning calorimetry and by capillary/metal block, using procedures designed to be compatible with Method A.1 Melting/Freezing Temperature of Commission Regulation (EC) No. 440/2008 of 30 May 2008 and Method 102 of the OECD Guidelines for Testing of Chemicals, 27 July 1995. As the test item decomposed, no value for melting point could be determined.
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).
