Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 04 September 2017 - 01 November 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Version / remarks:
- 30 May 2008
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Version / remarks:
- 27 July 1995
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- capillary method
- Remarks:
- Differential scanning calorimetry (thermal analysis) and a modified capillary / liquid bath method (visual evaluation)
- Specific details on test material used for the study:
- - Source and lot/batch No.of test material: A065/99
- Expiration date of the lot/batch: 1st July 2019
- Purity: UVCB - Key result
- Melting / freezing pt.:
- 131 °C
- Decomposition:
- yes
- Conclusions:
- The melting point of the test item could not be determined. The test item was determined to potentially lose a volatile fraction at approximately 131°C, before rapidly decomposing, prior to melting, with further, ongoing decomposition being evident as heating of the test item continued.
- Executive summary:
The melting point of naphthenic acids, lithium salts was determined in a GLP-compliant study following OECD guideline 102. The test item was determined to potentially lose a volatile fraction at approximately 131°C, before rapidly decomposing, prior to melting, with further, ongoing decomposition being evident as heating of the test item continued. Testing was performed by differential scanning calorimetry (thermal analysis) a modified capillary method with liquid bath (visual evaluation),

Additional information
The melting point of naphthenic acids, lithium salts was determined in a GLP-compliant study following OECD guideline 102. The test item was determined to potentially lose a volatile fraction at approximately 131°C, before rapidly decomposing, prior to melting, with further, ongoing decomposition being evident as heating of the test item continued. Testing was performed by differential scanning calorimetry (thermal analysis) and a modified capillary method with liquid bath (visual evaluation).
The melting points of the representative structures of lithium naphthenate were estimated using a QSAR model (MPBPVP v1.43 in EPISuite v4.11, US EPA 2010). The melting points of the representative structures for lithium naphthenate are estimated to be in the range of -20.85 - 262.29°C.
