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:
- 2012
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- Guideline compliant well documented 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.:
- >= 248 °C
- Atm. press.:
- 997 mBar
- Decomposition:
- yes
- Decomp. temp.:
- >= 248 °C
- Remarks on result:
- other: From 248°C the test item shows a boiling and/or thermal decomposition with evaporation of the decomposition products.
- Conclusions:
- boiling/decomposition at 248°C
- Executive summary:
In the Klimisch 1 non-GLP study from Kintrup (2012) the boiling point of Sodium di(1.3-dimethylbutyl) sulfosuccinate was determined with the DSC method according to OECD 103 to be at or above 248°C. At and above that temperature boiling or decomposition started. There is some indication from TGA that the test item decomposed.
This information is considered to be relevant and reliable for the further risk assessment.
Reference
The test item Sodium di(1.3-dimethylbutyl) sulfosuccinate shows a boiling and/or thermal decomposition at ca. 248 °C
(at 997 mbar) (a decomposition is most likely due to a strong residue in the crucible at ca. 600 °C (see TGA measurements)) according to the definition in the OECD guideline 103 (mean value from repeat determination; 1st heating run).
· 248 °C (from first measurement)
· 249 °C (from second measurement)
· 249 °C (from third measurement)
From 248 °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 248 °C the sample shows a weight loss of ca. 4-5 weight%) under the same measuring conditions
Description of key information
boiling/decomposition temperature: 248°C
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 248 °C
Additional information
In the Klimisch 1 non-GLP study from Kintrup (2012) the boiling point of Sodium di(1.3-dimethylbutyl) sulfosuccinate was determined with the DSC method according to OECD 103 to be at or above 248°C. At and above that temperature boiling or decomposition started. There is some indication from TGA that the test item decomposed.
For the risk assessment a boiling point of 248°C will be used.
This information is considered to be relevant and reliable for the further risk assessment.
Note: Due to the slightly different test design of the melting and boiling point study (open vs. closed crucible), a different melting/boiling/decomposition temperature was obtained in the OECD 102 and the OECD 103 study.
