- Type of method:
- differential scanning calorimetry
- Key result
- Melting / freezing pt.:
- 59 °C
- Atm. press.:
- 985 hPa
- Decomposition:
- no
- Sublimation:
- no
- 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).
Reference
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.
Description of key information
The melting point was determined to be 59 °C according to OECD 102.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 59 °C
Additional information
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).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
