Melting point / freezing point
Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 16th of February, 2010
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: A GLP study carried out to the relevant guidelines.
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Principles of method if other than guideline:
- An aliquot (15 ml) of test material was placed into a test tube containing a thermometer. A wire loop with which the sample could be agitated was placed inside the tube to ensure sample homogeneity during cooling. The test tube was surrounded by a glass jacket and then placed into a large beaker containing a dry ice/acetone mixture. The temperature and observations of the test material were recorded approximately every 30 seconds until the temperature reached a plateau, then every 300 seconds until completely frozen.
The determination was carried out in duplicate. - GLP compliance:
- yes (incl. QA statement)
- Type of method:
- thermal analysis
- Melting / freezing pt.:
- 269 K
- Conclusions:
- The freezing point of the test material has been determined to be 269 ± 0.5 K.
- Executive summary:
The freezing point of the test material has been determined to be 269 ± 0.5 K.
