Reference
Individual Results
To determine the boiling behaviour (three independent single measurements), the test item was heated up to 500 °C with a heating rate of 10 K/min. For the measurement a partially capsulated crucible, typical for boiling point measurements, was used.
424 °C (from first measurement)
424 °C (from second measurement)
424 °c (from third measurement)
From 424 °C the test item shows a boiling and/or thermal decomposition with evaporation of the decomposition components. The DSC measurements were confirmed by means of TGA measurements under the same measuring conditions.
Final Result
The test item Sodium Anisate shows a boiling and/or thermal decomposition earliest at ca. 424 °C (at 1012 mbar; mean value from repeat determination; 1st heating run).
Description of key information
Boiling point/thermal decomposition temperature is 424 ºC at 1012 mbar (OECD 103, DSC method).
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 424 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
