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:
- 2013
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- The study was conducted according to internationally accepted test guidelines and is considered reliable, but maybe less relevant and less adequate because of possible side reactions taking place at higher temperatures.
- 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:
- no
- GLP compliance:
- no
- Type of method:
- differential scanning calorimetry
- Boiling pt.:
- >= 155 °C
- Atm. press.:
- ca. 1 001 mBar
- Decomposition:
- yes
- Decomp. temp.:
- >= 155 °C
- Conclusions:
- The boiling temperature >= 155°C
- Executive summary:
The boiling temperature of the test item Fatty acids, C16-18 and C18-unsatd., compds. with triethanolamine was determined in accordance with the test method OECD Guideline Test 103 “OECD Guideline For The Testing Of Chemicals, adopted by the Council on 27th July 1995, Boiling Point” (similar to the test method A.2. "Boiling temperature" as described in the Official Journal of the European Communities L383A).
The test item Fatty acids, C16-18 and C18-unsatd., compds. with triethanolamine shows a boiling and/or thermal decomposition earliest at ca. 155 °C (at 1001 mbar) according to the definition in the OECD guideline 103.
Reference
From 155 °C the test item shows a boiling and/or thermal decomposition with evaporation of the decomposition components.
The DSC measurements were confirmed by means of TGA measurements (up to 155 °C the sample shows a weight loss of <1 weight%) under the same measuring conditions.
Description of key information
The test item shows a boiling and/or thermal decomposition earliest at 155°C at 1001 mbar.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 155 °C
