melting point/freezing point
Remarks:
pour point determined
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Comparable to guideline study with acceptable restrictions (e.g. non-GLP)
Qualifier:
equivalent or similar to
Guideline:
other: DIN ISO 3016 / ASTM D97
GLP compliance:
no
Other quality assurance:
other: DIN EN ISO 90001:2008, 14001:2005
Type of method:
pour point
Melting / freezing pt.:
-80 °C
Atm. press.:
1 013 hPa
Remarks on result:
other: based on the determination of the pour point, mean of two replicate measurements

Two measurements were performed, with the following results:

- 81°C;

- 79°C;

leading to a mean value of - 80 °C for the pour point.

Conclusions:
Pour point (DIN ISO 3016 / ASTM D 97): -80 °C.
Executive summary:

The melting point is estimated on the basis of the pour point, which was determined equivalent to DIN ISO 3016 / ASTM D 97 to be -80°C (mean of two replicate measurements: -81°C; -79°C).

Description of key information

Pour point (DIN ISO 3016 / ASTM D 97):  -80 °C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
