- Type of method:
- differential scanning calorimetry
- Key result
- Melting / freezing pt.:
- >= -26.2 - <= 20.5 °C
- Conclusions:
- Determination of the freezing/melting point of [Product Name] Di-octyldodecyl Dodecanedioate was determined via DSC (differential scanning calorimetry)
Three DSC measurements were performed.
In the cooling phase, a broad exothermic event was detected. According to the pre-test, this can be identified as the freezing point.
In the heating phase, a first event with an endothermic phase followed directly by an exo-thermic behavior can be interpret as a transition phase. The second event can be as-signed as the melting point.
Melting point and freezing point are indicated in a range.
Rate of temperature change was 10 K/min
Therefore, the results of this study under the test circumstances should be stated as fol-low:
The freezing range was determined as:
from -26.24 °C to -41.42 °C (246.91 K to 231.73 K)
The transition phase was determined as:
-22.63 °C to -2.26 °C (250.52 K to -2.26 K)
The melting range was determined as:
from -0.05 °C to 20.45 °C (273.10 K to 293.60 K)
These values represent from three independent determinations. - Executive summary:
Determination of the freezing/melting point of [Product Name] Dioctyldodecyl Dodecanedioate was determined via DSC (differential scanning calorimetry)
Three DSC measurements were performed.
In the cooling phase, a broad exothermic event was detected. According to the pre-test, this can be identified as the freezing point.
In the heating phase, a first event with an endothermic phase followed directly by an exothermic behavior can be interpret as a transition phase. The second event can be assigned as the melting point.
