Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 boiling range of TFEE-5 extrapolated to 101.325 kPa is 222-225 °C

Key value for chemical safety assessment

Additional information

The boiling point of TFEE-5 was 222-223 °C as determined by the method of Siwoloboff at 96.92 kPa per OECD TG103 and EC440/2008.A.2. This value was extrapolated to 225 °C at 101.325 kPa (standard pressure) using boiling points measured at 1 and 45 kPa. In addition, data from the vapour pressure study (obtained by dynamic ebulliometry according to OECD TG104 and EC440/2008.A.4, and in accord with GLP criteria) can be extrapolated to give a boiling temperature of 226 °C. The highest vapor pressure measured in this study was 90 kPa. Both studies are considered reliable with restrictions, but together support a boiling range of 222-225°C
