Melting point / freezing point

Link to relevant study record(s)

Reference

Endpoint:

melting point/freezing point

Type of information:

experimental study

Adequacy of study:

key study

Study period:

From 26 may 2016 to 30 june 2016

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

OECD Guideline 102 (Melting point / Melting Range)

Version / remarks:

1995

GLP compliance:

yes (incl. QA statement)

Type of method:

method to determine freezing temperature

Key result

Melting / freezing pt.:

< -50 °C

Atm. press.:

1 013.55 hPa

Conclusions:

2,2-Difluoroethyl acetate did not freeze or solidify at the low temperature threshold of the freezing temperature method i.e. -50.0°C (223 K).
Therefore, the freezing point of 2,2-Difluoroethyl acetate was reported as less than -50°C (< 223K) at 1013.55 hPa.

Executive summary:

The freezing point of 2,2-Difluoroethyl acetate was investigated in a GLP-compliant study according to OECD test guideline 102. The test substance was allowed to cool in an acetone/dry ice bath until -50°C (the temperature limit of the method used).

The test substance did not freeze or solidify at the low temperature threshold of the freezing temperature method i.e. -50.0°C (223 K).

Therefore, the freezing point of 2,2-Difluoroethyl acetate was reported as less than -50°C (< 223K).

Description of key information

The test substance did not freeze or solidify at the low temperature threshold of the freezing temperature method i.e. -50.0°C (223 K). Therefore, the freezing point of 2,2-Difluoroethyl acetate was reported as less than -50°C (< 223K).

Additional information

An experimental study performed under GLP compliance and in accordance with OECD test guideline 102 was flagged as a key study and assigned a Klimisch score of 1. It reports that 2,2-Difluoroethyl acetate does not freeze above to and including -50°C.
