Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Type of method:
method to determine freezing temperature
Key result
Melting / freezing pt.:
11 °C

In both determinations, the test substance initially supercooled in the liquid phase. The sample temperature then increased rapidly on the formation of an opaque solid, and demonstrated a stable freezing temperature plateau at 11.0 °C.

The freezing temperature of the test substance was determined to be 11.0 °C.
Executive summary:

The freezing temperature of the substance was determined under GLP according to OECD TG 102. The determination was performed in duplicate by placing an aliquot of approximately 15 mL of test substance in a test tube containing a thermometer. A wire loop was placed inside the tube to agitate the substance and ensure sample homogeneity during cooling. The test tube was surrounded by a glass jacket and placed into a large beaker containing a dry ice/acetone mixture. The temperature and observation of the test substance were recorded every 30 seconds. The freezing temperature observed in both determinations was 11.0 °C.
