Results and discussion
Melting / freezing point
- Key result
- Melting / freezing pt.:
- < -60 °C
- Atm. press.:
- ca. 1 013 hPa
- Decomposition:
- no
Any other information on results incl. tables
No endotherm relating to a melting temperature was observed, the melting point was
< -60°C. A relatively broad endotherm was seen starting at a mean temperature of 276°C (279.58°C test 1, 272.69°C test 2) suggesting boiling and decomposition. A dark brown residue remained in the crucibles at the end of the test. The thermograms are shown in Figure 11 and Figure 12 (attached).
Applicant's summary and conclusion
- Conclusions:
- The melting / freezing point of the test substance was found to be <-60 °C at 1013 hPa, under the conditions of the test.
- Executive summary:
In this guideline (OECD 102) study, [conducted with GLP certification], the melting point of the test substance (EC 7147-34-4) was found to be <-60 °C at 1013 hPa.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
