Specific details on test material used for the study:
Batch no.: 145
Appearance: white granular powder
Key result
Boiling pt.:
316 °C
Atm. press.:
1 004 mBar
Decomposition:
yes
Remarks:
thermal decomposition with evaporation of the decomposition components
Decomp. temp.:
316

Individual results:

316°C (from first measurement)

317°C (from second measurement)

315°C (from third measurement)

From 316°C, the test substance showed a boiling and/or thermal decomposition with evaporation of the decomposition components.

Conclusions:
Under the study conditions, the boiling and/or thermal decomposition of the substance was determined to be earliest at 316°C.
Executive summary:

A study was conducted to determine the boiling point of the substance according to OECD Guideline 103 and EU Method A.2. To determine the boiling behaviour (three independent single measurements), the test substance was evaluated by differential scanning calorimetry (DSC) between 5°C and 550°C with a heating rate of 10K/min. For the measurement, a partially capsulated crucible - typical for boiling point measurements - was used. Under the study conditions, the boiling and/or thermal decomposition of the susbtance was determined to be earliest at 316°C (Kintrup, 2016).

Description of key information
