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
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling point/boiling range)
- GLP compliance:
- no
- Type of method:
- differential scanning calorimetry
- Key result
- Boiling pt.:
- > 235 °C
- Decomposition:
- yes
- Decomp. temp.:
- > 235 °C
- Remarks on result:
- other: From 235 °C the test item shows a boiling and/or thermal decomposition with evaporation of the decomposition components.
- Conclusions:
- Boiling point > 235°C. Above that temperature, decomposition started.
- Executive summary:
The In the non-GLP Klimisch 1 study from Kintrup (2012) the boiling point of Reaction products of ricinoleic acid with 2-aminoethanol and maleic acid and sodium hydrogensulfite was determined with the DSC method according to OECD 103 to be above 235 °C. Above that temperature, decomposition started.
This information is considered to be relevant and reliable for the further risk assessment.
Reference
The test item Reaction products of ricinoleic acid with 2-aminoethanol and maleic acid and sodium hydrogensulfite shows a boiling and/or thermal decomposition at ca. 235 °C (at 1022 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).
235 °C (from first measurement)
236 °C (from second measurement)
235 °C (from third measurement)
From 235 °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 235 °C the sample shows a weight loss of ca. 3-4 weight%) under the same measuring conditions.
Description of key information
Boiling/decomposition: 235°C
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 235 °C
Additional information
The In the non-GLP Klimisch 1 study from Kintrup (2012) the boiling point of Reaction products of ricinoleic acid with 2-aminoethanol and maleic acid and sodium hydrogensulfite was determined with the DSC method according to OECD 103 in a non-GLP study to be above 235 °C. Above that temperature, decomposition started.
