Key result
Melting / freezing pt.:
< -20 °C

During an evaluation test run at -27.0°C, the sample did not freeze. At the request of the sponsor, a repeat test was performed and it was confirmed that the sample did not freeze at temperatures down to -20.0°C.

Conclusions:
The freezing point of Fluorosulfonic Adduct is lower than -20.0°C.
Executive summary:

The determination of the freezing point of Fluorosulfonic Adduct was carried out by a direct measurement according to the EU Method A.1 and the OECD Guideline No. 102 under GLP compliance.

The substance was placed in a special jacketed glassware which was temperature controlled and cooled by a refrigerator unit circulating silicone oil. The sample was stirred gently and continuously during cooling and the temperature was measured at suitable intervals (e.g. 0.5 min). As soon as the temperature remained constant for a few readings or crystals were observed in the sample, the temperature was recorded as the freezing point.

The freezing point of Fluorosulfonic Adduct is lower than -20.0°C.

Description of key information

The freezing point of Fluorosulfonic Adduct is lower than -20.0°C.

Key value for chemical safety assessment
