Key result
Melting / freezing pt.:
59 °C
Atm. press.:
985 hPa
Decomposition:
no
Sublimation:
no

During the heating phase an endothermic effect was observed in the temperature range of 50 – 70 °C, which can be assigned to the melting of the test item. As the onset temperatures in both tests deviate by less than 0.5 K from their mean value of 58.96 °C, the test item has a melting point of 59.0 °C.

Conclusions:
The melting point was determined to be 59 °C according to OECD 102.
Executive summary:

The test item has a melting point of 59.0 °C at atmospheric pressure (985 hPa) as determined by differential scanning calorimetry according to Regulation EC No. 440/2008 Method A.1. and OECD Test Guideline 102 (1995).

Description of key information

The melting point was determined to be 59 °C according to OECD 102.
