- Decomposition:
- yes
- Decomp. temp.:
- 263 °C
- Remarks on result:
- not determinable
- Conclusions:
- As the test item decomposed from approximately 263 °C (536 K) at 100.7 kPa , no value for boiling temperature could be determined.
- Executive summary:
The boiling point of the test item has been determined by differential scanning calorimetry, designed to be compatible with Method A.2 Boiling Temperature of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 103 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.
As the test item decomposed from approximately 263 °C (536 K) at 100.7 kPa, no value for boiling temperature could be determined.
Reference
There was a wide shallow endotherm observed in determinations 1 to 4 however this was suppressed when using pre-pierced crucibles (determinations 5 & 6) and resulted in no mass loss based on determinations 3 and 4. Also the remaining reside after determinations 3 and 4 showed little change in appearance from the initial observation. Therefore, while it was not possible to determine the origin of this thermal event, it was not considered significant.
From approximately 263 °C, an exothermic event began which did result in changes in test item appearance and loss of mass. This has been assigned to decomposition of the test item.
As a result of the low rate of enthalpy change during decomposition, the onset temperature could only be approximated.
Description of key information
As the test item decomposed from approximately 263 °C (536 K) at 100.7 kPa , no value for boiling temperature could be determined.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 263 °C
Additional information
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
