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:
- 2001-02-22 - 2002-01-17
- Reliability:
- 1 (reliable without restriction)
- Reason / purpose for cross-reference:
- reference to other study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling point/boiling range)
- Deviations:
- no
- Principles of method if other than guideline:
- NA
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Remarks:
- ASTM E 537-76
- Key result
- Atm. press.:
- 1 013.25 hPa
- Decomposition:
- yes
- Remarks:
- before boiling
- Decomp. temp.:
- >= 140 - <= 200 °C
- Conclusions:
- The test substance was determined to decompose before boiling. Thus, it does not possess a boiling temperature.
- Executive summary:
A single exotherm reaction was observed in the region 140-200°C, which can be attributed to the decomposition of the sample. An endotherm reaction occurred in the range 235 – 250°C, which corresponds to the melting of the decomposed sample that was observed in the melting point test (see: Sec.: 4.1).

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.
