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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Results and discussion
Boiling point
- Key result
- Decomposition:
- yes
- Decomp. temp.:
- >= 250 °C
- Remarks on result:
- not determinable
- Remarks:
- The initial three hour hold at about 80°C should have caused any water and ammonia to evaporate off the sample as well as any residual (perfluorohexyl)ethyl alcohol. That gives a % non-volatiles measurement of 28.2%. The remaining solids begin degrading at about 100°C but very slowly, only losing about 0.5% over the course of an hour. With each temperature increase, the rate of mass loss seems to increase marginally until about 250°C where anything left evaporated or sublimed. It has been assessed that therer is no obvious melting point or boiling point for thie substance and that it decomposes slowly over the temperature range between 100 - 250C but then sublimes above this temperature.
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
