- Key result
- Melting / freezing pt.:
- 33 °C
- Atm. press.:
- ca. 1 atm
- Key result
- Melting / freezing pt.:
- 200 °C
- Atm. press.:
- ca. 1 atm
- Conclusions:
- Under the study conditions, two melting points were detected for the solvent free test substance. The first (33°C) is the transition between solid and paste, the latter (200°C) between paste and liquid.
- Executive summary:
A study was conducted to determine the melting point of the test substance, C16 -18 ADBAC (>97% active) using differential scanning calorimetry (DSC), according to ASTM E 537 – 07 Method. Under the study conditions, two melting points were detected for the solvent free test substance. The first (33°C) is the transition between solid and paste, the latter (200°C) between paste and liquid (Ulama, 2010).
Reference
2 melting points were detected for the solvent free test substance. The first (33°C) is the transition between solid and paste, the latter (200°C) between paste and liquid.
Description of key information
The melting point of the test substance was determined using the differential scanning calorimetry (DSC), according to ASTM E 537 – 07 Method (Ulama, 2010).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 33 °C
Additional information
(two melting points: 33°C for transition between solid and paste, and 200°C for transition between paste and liquid)
