melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
18 Dec 2015 - 25 Jan 2016
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
GLP compliance:
no
Type of method:
thermal analysis
Remarks:
DSC
Melting / freezing pt.:
>= -2 - <= 50 °C
Atm. press.:
ca. 1 013 hPa

To determine the melting behaviour (three independent single measurements), the test item was measured by DSC between -90 °C and 300 °C with a heating /cooling rate of 10 K/min in 4 cycles. For the measurement a capsulated crusible was used.

-1 °C - 52 °C (from first measurement)

-4 °C - 48 °C (from second measurement)

The cooling run shows a begin of crystallization at ca. 3 °C. Additionally the heating runs show a glass transition temperature at -47 °C (1st heating run). In the 2nd heating run the test item shows a melting although.

Description of key information

-2 °C - 50 °C at ca. 1013 hPa (OECD 102)

Key value for chemical safety assessment

Additional information

The melting point of the substance was determined by Differential Scanning Calorimetry. The temperature range represents the melting area of crystalline subcomponents. The cooling run shows a beginning of cristallization at 3 °C.
