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:
- February 2010
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Differrential scanning calorimetry and visual observation
- GLP compliance:
- no
- Type of method:
- differential scanning calorimetry
- Specific details on test material used for the study:
- 5 differents test item were used
- Melting / freezing pt.:
- >= -10 - <= 35 °C
- Decomposition:
- no
- Remarks on result:
- other: pressure not specified but assumed to be ambient
- Conclusions:
- It was very difficult to determine the melting point of test item.
From tests performed with 5 different samples, the following range was stated: -10°C - 35°C. - Executive summary:
The study was performed to determine the melting point of test item using DSC and heating/cooling phase with visual observation.
It was very difficult to determine the melting point of test item.
From tests performed with 5 different samples, the following range was stated: -10°C - 35°C.
Reference
DSC results:
Melting peaks were observed only on the DSC analysis of sample 4: two peaks observed around 20°C and 35°C.
For other samples, DSC analysis didn't give reliable results.
The DSC measurement was not an appropriate method to determine the test item melting point.
Additionals studies:
First test: -10°C for 10 hours
The freezing point of sample 2 was <-10°C.
The freezing point of sample 1 was determined to be between -10°C and 20°C.
Second test: 4°C for 5 hours
Sample 1 didn't change and was still solid.
Third test: heating in a water bath
Sample 1 still at solid state was heated in the water bath.
The test item started to melt at 30°C.
Description of key information
A melting range was stated as: -10°C - 35°C
Key value for chemical safety assessment
