Boiling point
Administrative data
Link to relevant study record(s)
- Endpoint:
- boiling point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EPA OPPTS 830.7220 (Boiling Point / Boiling Range)
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Boiling pt.:
- >= 258 - <= 271 °C
- Atm. press.:
- ca. 1 013
- Remarks on result:
- other: boiling range
- Conclusions:
- The test item had a boiling range between 258 °C and 271 °C.
- Executive summary:
The determination of the boiling point was carried out according to OECD Test guideline 103 and the
European Commission Council Regulation (EC) No. 440/2008, Annex, Part A, A.2 by differential scanning calorimetry (DSC).In a defined atmosphere (nitrogen) the test item was heated up from ambient temperature to the final temperature (400 °C) at a constant heating rate (10 K/min). The quantity of heat absorbed or released was measured and recorded. Aluminium crucibles with a small hole were used as containers for the test item and as empty reference crucible. The test item had a boiling range between 258 °C and 271 °C.
Reference
Two measurements in aluminium crucibles with a hole showed an endothermic effect (boiling) in the temperature range of 230 - 290 °C.
Boiling point (DSC measurement)
| Onset /°C | Temperature range / °C |
| 271.16 | 230 - 290 |
| 257.96 | 230 - 280 |

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.
