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:
- 2016
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling point/boiling range)
- Deviations:
- no
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Deviations:
- not applicable
- Principles of method if other than guideline:
- METHOD:
- The sample was closed up in a crucible made of aluminium and heated up in a DTA/DSC system
- Heating rate 5 K/min
- The temperature difference and the heat effect were recorded - GLP compliance:
- no
- Type of method:
- other: Differential Thermal Analysis (DTA)/Differential Scanning Calorimetry (DSC)
- Decomposition:
- yes
- Decomp. temp.:
- 375 - 450 °C
- Remarks on result:
- other: No definite boiling point could be detected up to the decomposition of the test item.
- Conclusions:
- No definitive boiling point could be determined. The alleged boiling range was 245-370 °C.
- Executive summary:
A differential thermoanalysis method (DTA) was used to determine the boiling point which conforms with the procedure Test method A.2, "Determination of the boiling point", described in the EC-Guideline. A boiling range of the test item between approx. 245 to 370 °C could be observed. After the boiling process a decomposition of the substance seems to take place. This is supported by the light yellowish colour of the residue in the crucible. Between 375 °C and 450 °C another endothermic effect could be observed.
Reference
No definite boiling point could be detected up to the decomposition of the test item.
Between approx. 245 °C and 370 °C an endothermic effect was visible. This appears to be the boiling range of the test item. Additionally a decomposition of the test item seems to take place. This assumption is supported by the light yellowish colour of the residue in the crucible. Between 375 °C and 450 °C another endothermic effect could be observed.
Description of key information
No definitive boiling point could be determined. The alleged boiling range was 245-370 °C.
Key value for chemical safety assessment
Additional information
Between approx. 245 °C and 370 °C an endothermic effect was visible. This appears to be the boiling range of the substance. Additionally a decomposition of the test item seems to take place. This assumption is supported by the light yellowish colour of the residue in the crucible. Between 375 °C and 450 °C another endothermic effect could be observed.
