Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
6 °C

Additional information

Instead of a melting point, a pour point of 6°C ± 3°C was determined (Reimer 2001c). A melting point could not be observed using the differential scanning calorimetric (DSC) method because an endothermic event was not observed in the heat flowvstemperature plot. The pour point (the lowest temperature at which the test substance is first observed to flow on warming) is an appropriate measurement for viscous liquid substances. The test was conducted according to ASTM Method D97, as recommended in the OECD 102 guideline.
