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:
- July 9, 2008 - September 16, 2008
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- yes
- Remarks:
- The main test was not performed in duplicate, but a preliminary test was performed
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Qualifier:
- according to guideline
- Guideline:
- other: ISO 1392 Determination of crystallizing point, 1977
- Principles of method if other than guideline:
- The freezing point was determined by cooling the test item in sample tubes following study guidelines. The temeperature during crystallization was observed.
The freezing temperature of the test item is defined as the temperature at which phase transition from liquid to solid state take place at normal atmospheric pressure - GLP compliance:
- yes (incl. QA statement)
- Type of method:
- method to determine freezing temperature
- Specific details on test material used for the study:
- Batch No. 512051

Colourless liquid - Key result
- Melting / freezing pt.:
- ca. -8 °C
- Atm. press.:
- ca. 1 atm
- Conclusions:
- The freezing temperature of the test item was determined at -8 ° C.
- Executive summary:
The freezing point was determined by cooling the test item in sample tubes following study guidelines (EU method A.1, OECD 102, ISO 1392).
The temperature of the test item decreased continuously. Starting from 20 ° C, the test item was cooled to -40 ° C. The freezing temperature of the test item was determined at -8 °C. At the end of the experiment, the test item was solid.
Reference
The temperature of the test item decreased continuously. Starting from 20 °C, the test item was cooled to -40 °C.
