Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Applicant's summary and conclusion

Conclusions:
Solid acrylamide sublimes near its melting point (85°C) with a vapour pressure of 230 Pa. The vapour pressure of acrylamide solutions (50%) at 25°C is < 2.5 kPa, the partial vapour pressure of acrylamide above the solution is 2.3 Pa and the vapour concentration of acrylamide in a saturated atmosphere above an aqueous solution is approximately 0.0003% (3ppm).
