- Key result
- Melting / freezing pt.:
- < -50 °C
- Decomposition:
- no
- Sublimation:
- no
- Remarks on result:
- other: Pressure not specified but assumed to be ambient
- Conclusions:
- Freezing point was determined according to OECD Guideline 102 (Melting point / Melting Range) and EU Method A.1 (Melting / Freezing Temperature), No freezing was observed down to a temperature of - 50 °C (223.15 K) Therefore, Freezing point of test item is < - 50 °C (223.15 K).
- Executive summary:
Freezing point was determined according to OECD Guideline 102 (Melting point / Melting Range) and EU Method A.1 (Melting / Freezing Temperature).
No freezing was observed down to a temperature of - 50 °C (223.15 K) Therefore, Freezing point of test item < - 50 °C (223.15 K).
Reference
Preliminary test
The preliminary test was performed as described. No congealing was observed down to a temperature of - 50 °C.
Main test
As no congealing was observed in the preliminary test, no further tests were undertaken.
Calibration of the thermometer
The thermometer was checked against a certified thermometer just before the test in an ice-water mixture. The correction to be applied is -0.1 K.
Description of key information
The freezing point of test item was stated as below 223K (-50°C). Test item is liquid at ambient temperature.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -50 °C
Additional information
A fully reliable experimental study, conducted according to a recognized OECD/EC method and under GLP, is available. It is considered as a key study.
