The DSC measurements were
performed twice. After cooling to -150°C at a rate of 2 K/min the sample
was heated to 35°C at a rate of 10 K/min. The cooling as well as the
heating curve show only a glass transition, indicating that the test
item had solidified amorphously. No other thermal effect from
crystallisation or melting was registered upon further heating, see
attached DSC thermograms.
Melting temperature: No melting
point was found between -150 and +35°C under these conditions. A glass
transition was observed at -122°C / -122°C.
Melting point: no melting observed between -150 and +35°C at 1013 hPa (OECD 102)
In a DSC study conducted in
accordance with OECD Test Guideline 102 and in compliance with ISO
17025, no melting was observed for the test substance under the
conditions of the test between -150 and +35°C at 1013 hPa, but a glass
transition was observed at -122°C. The result is considered to be
reliable and is selected as key study.
In a secondary source to which no
reliability could be assigned, a limit melting point of <-80°C was
reported for the substance.
