- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Version / remarks:
- 27 July 1995
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Version / remarks:
- 30 May 2008
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Remarks:
- and capillary/metal block
- 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.
- 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.
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%).
