- Key result
- Melting / freezing pt.:
- 135.8 °C
- Atm. press.:
- 1 013.25 hPa
- Decomposition:
- no
- Sublimation:
- no
- Conclusions:
- The melting point was determined to be 135.8 °C at 1013.25 hPa.
- Executive summary:
The melting point of the test item was determined according to EU Method A.1.
The dry substance was finely pulverized and put into three capillary tubes. The filling level was approximately 4 to 5 mm after the sample has been tightly packed. The bath was heated so that the temperature rise is approximately 0.5 °C/min. A set point of 134 °C and maximum point of 144°C was chosen. The melting point was measured in triplicate. The melting point was determined to be 135.8 °C at 1013.25 hPa.
