Boiling point
Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2010-05-10 to 2010-05-11
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling point/boiling range)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- differential scanning calorimetry
- Decomposition:
- yes
- Decomp. temp.:
- ca. 330 °C
- Remarks on result:
- other: The test item started to decompose at at 330°C and the decomposition product started boiling at 398°C.
- Conclusions:
- As the substance started decomposing at approximately 330°C before boiling, no boiling point could be determined.
- Executive summary:
The test item started to decompose at 330°C and the decomposition product started boiling at 398°C.
Reference
The DSC-measurement under nitrogen indicates an endothermic effect in the temperature range 90 -140°C (onset 117°C). The test item started melting. A 2nd endothermic effect was observed in the temperature range 350 -480°C due to decomposition and boiling of the substance. A black residue remained at the end of the test after cooling in the crucible. Approx. 86% of the material had volatilized from the crucible during the test. Measurements of the capillary method confirmed the results.
Description of key information
As Fatty acids, C16 -18, zinc salts started decomposing at approximately 330 °C before boiling, no boiling point could be determined.
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.
