Reference
Boiling point / boiling range: DSC measurement
Two DSC measurements in aluminium crucibles with a hole showed no further endothermal effects after the melting/decomposition. Additionally, a multistage exothermal effect starting at approx. 320 °C was observed. After the measurement the test item was a black residue. The mass loss after the DSC measurement amounted to 50 % and 48 %, respectively.
The results of the DSC measurements are summarized in Table 3.
Table 3: Boiling point (DSC measurement)
| Ident No. | Test item / mg | Starting temperature / °C | Final test temperature / °C | Temperature range / °C | Onset (boiling) / °C | Crucible | Observations after the measurement |
| 38800 | 10.84 | 25 | 500 | 320 – 460 (multistage exothermal) |
-- | Aluminium with a hole | Test item was a black residue; mass loss: 50 % |
| 38801 | 6.90 | 25 | 500 | 320 – 460 (multistage exothermal) |
-- | Aluminium with a hole | Test item was a black residue; mass loss: 48 % |
The test item had no boiling point under atmospheric conditions. Decomposition started during the melting.
Description of key information
