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:
- 20 May 2015
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with national standard methods
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- - Principle of test:
Melting point is determined by the use of differential scanning calorimetry (DSC) in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature.
- Method:
Fill a DSC pan with ± 1 to 5mg sample and record the sample weight
Close the DSC sample pan with a pan cover using a pan press
Place the sample pan into the sample position of the DSC
Prepare an empty reference pan and place it into the reference position of the DSC
Start the analysis
- Short description of test conditions:
1: Sampling interval 0.10 sec/pt
2: Equilibrate at 40.00°C
3: Isothermal for 5.00 min
4: Ramp 5.00°C/min to 350.00°C
5: End of method - GLP compliance:
- not specified
- Type of method:
- differential scanning calorimetry
- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material: 8135N/ lot: 021340 - Key result
- Melting / freezing pt.:
- > 350 °C
- Conclusions:
- No melting point or other phase transitions are observed before 350°C. Melting point is etimated to be greater than 350°C. The test item shows exothermal decomposition starting around 225°C.
