Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

The water solubility of chlorotrifluoroethylene is 380 mg/L at 28°C.

Key value for chemical safety assessment

Water solubility:
380 mg/L
at the temperature of:
28 °C

Additional information

A well documented study is available reporting that chlorotrifluoroethylene has a water solubility of 380 mg/L at 28°C. This value was evaluated in a completely sealed system and with the atmosphere saturated with the gas. Hence the measured value of water solubility represents an overestimation of the real water solubility of CTFE at ambient condition.

Information regarding the water solubility of

chlorotrifluoroethylene was also sourced from two secondary and non-peer reviewed sources of Klimisch-4 reliability which, although non-valid, agree on the fact that the substance is moderately soluble in water.

One additional secondary and non-peer reviewed source of Klimisch-4 reliability reports that the substance has a water solubility of 4.5g/L at 25°C, these data, conflicting with the rest of the reported values, has not been included in this assessment.

One secondary source of Klimish-2 reliability states that the substance is insoluble in water without reporting any punctual data.
