Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 17 DEC 2010 - 17 JAN 2011
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Reason / purpose for cross-reference:
- reference to same study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Version / remarks:
- European Commission Regulation (EC) No. 440/2008
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- Version / remarks:
- 1995
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- differential scanning calorimetry
- Decomposition:
- yes
- Remarks on result:
- not determinable
- Conclusions:
- The test item melted under decomposition. No boiling was observed.
- Executive summary:
The boiling point of the sample was tested according to EU Method A.2 and OECD Guideline 103 in a non-GLP study. The test item melted under decomposition, therefore no boiling could observed.
Reference
The DSC-measurement of the pre-test in a closed glass crucible with the test item showed an endothermal effect in the temperature range 210 - 225 °C, followed by an exothermic effect in the temperature range 245 °C to 295 °C. At the final temperature of 300 °C a black liquid was observed in the closed glass crucible.
The thermograms show broad multi-stage endothermic signals in the temperature range of about 205 to 350 °C. After the measurements the test item appeared as a black residue. The relative mass loss increased with higher final temperature of the measurement. The test item melted in a temperature range of 170 - 290 °C under decomposition. A boiling was not observed.
Description of key information
The boiling point of the sample was tested according to EU Method A.2 and OECD Guideline 103 in a non-GLP study. The test item melted under decomposition, therefore no boiling could observed.
Key value for chemical safety assessment
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.
