Administrative data
Link to relevant study record(s)
- Endpoint:
- temperature of decomposition (state purity)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 18 November 2020 - 10 March 2021
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- Version / remarks:
- 27 July 1995
- Deviations:
- no
- GLP compliance:
- no
- Remarks:
- The study was conducted in a laboratory that operates in accordance with GLP principles; however, no claim of GLP compliance was intended nor is made for this study.
- Type of method:
- differential scanning calorimetry
- Specific details on test material used for the study:
- EC No.: 950-853-6
Appearance/Physical state: solid (deliquescent)*
Batch: 209-653 (dried material from [Tradename] batch number 0001569403)
Purity: ~94.5%*
Expiry / Retest date: 03 December 2021
Storage conditions: ambient temperature, in the dark, under nitrogen
* As the test item is a deliquescent solid and the samples used in this study were all viscous liquids, it indicates the solid had absorbed up to 10% water. The purity of the liquid samples was therefore 85.05%. - Key result
- Atm. press.:
- >= 102 - <= 103 kPa
- Decomposition:
- yes
- Decomp. temp.:
- 239 °C
- Remarks on result:
- other: As the test item decomposed, no value for boiling point could be determined
- Conclusions:
- The test item has been determined to decompose from approximately 239 °C (512 K) at 102 to 103 kPa. As the test item decomposed, no value for boiling point could be determined.
- Executive summary:
The determination of boiling point was carried out by differential scanning calorimetry, using a procedure designed to be compatible with Method 103 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.
Aliquots of test item were placed in crucibles with a manually pierced lid and subjected to a thermal program. A broad, shallow endotherm occurred from approximately 57 °C up to approximately 236 °C in the six determinations. It was considered this was due to loss of moisture from the test item. The endotherm continued past the boiling point of water, probably due to the viscous nature of the test item hindering this evapouration. Following this, a broad, complex endotherm started from approximately 239 °C which was attributed to the test item decomposing and evapouration of the decomposition products.
The test item has been determined to decompose from approximately 239 °C (512 K) at 102 to 103 kPa. As the test item decomposed, no value for boiling point could be determined.
Reference
The presence of up to 10% absorbed moisture in the test item was considered not to significantly affect the boiling point test as the moisture is boiling off as the sample is heated. This effectively gives a dry test item which is then exposed to heating. Additionally, Determination 6 heated the test item to remove the moisture, cooled and then heated the dried test item to observe any differences.
Description of key information
The test item has been determined to decompose from approximately 239 °C (512 K) at 102 to 103 kPa. As the test item decomposed, no value for boiling point could be determined.
Key value for chemical safety assessment
- Temperature of decomposition (state purity):
- 239 °C
