Key result
Decomposition:
yes
Decomp. temp.:
238 °C
Remarks on result:
other: atmospheric pressure not specified

The test substance showed no melting of the main component up to 238°C according to the definition in the OECD guideline 102 (mean value for repeat determination).

239°C (from first measurement)

236°C (from second measurement)

240°C (from third measurement)

From 238°C, the test substance showed an exothermic effect (decomposition presumably; a melting >238°C can't be excluded).

In the third heating, the test substance showed an endothermic effect (possibly decomposition; no melting of main component).

Conclusions:
Under the study conditions, the substance showed no melting of the main component up to 238°C. From 238°C, the substance showed an exothermic effect with decomposition.
Executive summary:

A study was conducted to determine the melting point / freezing point of the susbtance according to OECD Guideline 102 and EU Method A.1. To determine the melting behaviour (three independent single measurements), the test substance was measured by differential scanning calorimetry (DSC) between -90°C and 350°C with a heating/cooling rate of 10 K/min in 4 cycles. For the measurement, a capsulated crucible was used. Under the study conditions, the substance showed no melting of the main component up to 238°C. From 238°C, the substance showed an exothermic effect with decomposition (Kintrup, 2016).
