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:
- 30 June 2004 to 21 August 2004
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Remarks:
- As the material decomposed, no value for boiling point could be determined. The result is estimated from vapour pressure data.
- Reason / purpose for cross-reference:
- reference to other study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling point/boiling range)
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- differential scanning calorimetry
- Key result
- Boiling pt.:
- 470 K
- Atm. press.:
- 101.325 kPa
- Decomposition:
- yes
- Decomp. temp.:
- 436 K
- Remarks on result:
- other: As the material decomposed, no value for boiling point could be determined. The result is estimated from vapour pressure data.
- Conclusions:
- From vapour pressure data, the boiling point was estimated to be 470 K at 101.325.kPa.
- Executive summary:
The test material decomposed from approximately 436 ± 0.5 K at 101.57 kPa, by differential scanning calorimetry, using ASTM E537-86, Method 103 of the OECD Guidelines for Testing of Chemicals, 27, July 1995. As a result of the low inital rate of enthalpy change during decomposition, the onset temperature could only be approximated. As the test material decomposed, no value for boiling point could be determined. The test material has been determined to decompose from approximately 436 ± 0.5 K at 100.57 kPa. From vapour pressure data, the boiling point was estimated to be 470 K at 101.325.kPa.
Reference
Thermograms and thermographic data for Determinations 1 and 2 are shown in the attached figures.
Overall decomposition temperature: from approximately 436 ± 0.5 K
As the test material decomposed, no value for the boiling temperature could be determined. From data obtained in the key vapour pressure study, the boiling point of the test material was estimated to be 470 K at 101.325 kPa.
As a result of the low initial rate of enthalpy change during decomposition, the onset temperature could only be approximated.

Description of key information
The key study was chosen on the basis that it was conducted to a recognised guideline and GLP and is therefore the most reliable data. From vapour pressure data, the boiling point was estimated to be 470 K at 101.325 kPa.
The test material has been determined to decompose from approximately 436 ± 0.5 K at 100.57 kPa.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 470 K
