- Conclusions:
- The freezing point of the substance is -14.5 °C at standard atmospheric pressure.
- Executive summary:
The freezing point of the test substance was determined in accordance with EU Method A.1. Test substance was filled into a solidification tube with a diameter ranging from 18 to 25 mm. The substance was then cooled down and stirred slowly and continuously with a precision thermometer (Amarell, serial number 8442, range -30 to +30 °C, fractional division 0.1 °C, uncertainty 0.03 °C). The freezing point is reached when the temperature remains constant. The freezing point was determined to be -14.5 °C under atmospheric pressure of 1013 hPa.
Reference
Two individual measurements were made, both yielding freezing points of -14.5 °C.
Description of key information
-14.5 °C
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -14.5 °C
Additional information
The freezing point of the test substance was determined in accordance with EU Method A.1 to be -14.5 °C. This value is supported by handbook data reporting a freezing point in the range of -12.4 to -15 °C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
