Expiry date: Nov. 2018
Storage: Room Temperature (20 ± 5°C) - Key result
- Melting / freezing pt.:
- > 103.48 - < 103.55 °C
- Decomposition:
- yes
- Decomp. temp.:
- ca. 375.51 °C
- Sublimation:
- no
- Conclusions:
The melting point under these circumstances as the endothermic event is:
103.53 ± 0.05 °C (376.68 ± 0.05 K)
This value is the mean of two independent determinations. The beginning of decomposition should be stated with: 375.51 °C (648.66 K). This value is the lowest value of two independent determinations.- Executive summary:
The determination of the melting / boiling point was determined via DSC (differential scanning calorimetry). In both DSC measurements one endothermic event was detected. In accordance to the pre-test the first endothermic event can be identified as melting point, evaluated with the onset function.
In the further process a turbulent baseline was observed which probably supposed to be beginning of decomposition.
The melting point under these circumstances as the endothermic event should be stated with:
103.53 ± 0.05 °C (376.68 ± 0.05 K)
This value is the mean of two independent determinations. The beginning of decomposition should be stated with: 375.51 °C (648.66 K). This value is the lowest value of two independent determinations.
Reference
Values DSC Test Item first determination
Melting Point Temperature [°C] 103.56 (Onset), energy [J/g] 55.98
Beginning of decomposition Temperature [°C] 375.51, energy [J/g] 15.6
Values DSC Test Item second determination
Melting Point Temperature [°C] 103.49 (Onset), energy [J/g] 56.93
Beginning of decomposition Temperature [°C] 377.54, energy [J/g] 15.6
The deviation of melting point between the first and second determination was < 0.5 K; therefore, no further determination needs to be performed.
