Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Vapour pressure
Temp.:
25 °C
Vapour pressure:
< 1 Pa
Remarks on result:
other: Vapor pressure for start material known. Prediction for product done.

Any other information on results incl. tables

The vapour pressure for CapaMonomer is 0.8 Pa (experimetal result) and for 1,6-hexanediol 0,05 Pa (calculated with MPBPWIN).


 


The reaction products would have a lower vapour pressure than the start material because the molecule is larger. The boiling point for


Capa™ 2047A is above 252 °C and for CapaMonomer 241 °C. The higher boiling point the lower vapour pressure. That is confirmed by the GC determination of purity where the difference in retention time corresponds to the size of the molecule. 

Applicant's summary and conclusion

Conclusions:
Vapor pressure is < 1 Pa.
