Reference
Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2006-11-01 to 2006-11-29
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: Guideline study
Qualifier:
according to
Guideline:
EU Method A.1 (Melting / Freezing Temperature)
Version / remarks:
December 1992
Deviations:
no
Qualifier:
according to
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Version / remarks:
adopted 27th July 1995
Deviations:
no
GLP compliance:
no
Remarks:
ISO 9001 compliance
Type of method:
thermal analysis
Melting / freezing pt.:
ca. -113 °C
Atm. press.:
1 020 hPa
Remarks on result:
other: no melting point detected; glass transition / amorphous solidification

The DSC-curve shows no melting peak, but an endothermic Cp-step at -113 °C overlapped by a relaxation peak. This thermodynamic behaviour is characteristic for a glass transition, that means the test item solidifies amorphously.

Conclusions:
THFMA is reported to undergo glass transition (amorphous solidification) at -113°C.
Executive summary:

THFMA is reported to undergo glass transition (amorphous solidification) at -113°C (determined according to OECD guideline 102, adopted 27th July 1995, and EU Method A.1, December 1992; differential scanning calorimetry).
