- Melting / freezing pt.:
- > 600 °C
- Decomposition:
- yes
- Decomp. temp.:
- 150 °C
- Conclusions:
- No melting point of the test item was recorded up to 600°C. Decomposition started from 150°C.
- Executive summary:
The objective of the study was to determine the temperature at which the test item changes from the solid state to the liquid state, using the Differential Scanning Calorimetry method (DSC), according to the OECD 102 guideline and EC A1 method and under GLP conditions.
No melting point of the test item was recorded up to 600°C. Decomposition started from 150°C.
Reference
In two assays, no melting point was observed up to 600 °C. In both cases decomposition was observed from 150 °C.
Reference items tested and passing conformity: Tin wire, Indium wire and Zinc wire.
Description of key information
For the reaction mass of TFSK/TFAK, no melting point was observed up to 600°C. Decomposition was observed from 150°C.
Key value for chemical safety assessment
Additional information
For the reaction mass of potassium trifluoromethanesulphinate and potassium trifluoroacetate, no melting point was observed up to 600°C. Decomposition was observed from 150°C.
