Values Pre-Test

 5 °C  - 20 °C - 80 °C
 liquid  liquid-solid  solid

Values Main Study

 Melting range  Begin  End
 First determination  -38.7 °C  -33.0 °C
 Second determination  -38.2 °C  -32.5 °C

A melting range is stated.

The determination was performed in duplicate. In both determinations, a melting range was detected.
The melting range was determined as -38.5 to -32.8 °C (234.8 to 240.5 K). This value is the mean of two indipendent determinations.

Description of key information

A melting range of -38.5 to -32.8 °C was stated.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-38.5 °C
