Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

25 °C

Additional information

The Henry’s law constant for aqueous peracetic acid solution was determined over the temperature range of 278°-293°K by measuring the vapour pressure in a gas stream of nitrogen or air that was in equilibrium with the solution of known peracetic acid concentration. It was determined to be 467.6 M atm-1. This corresponds to 0.217 Pa m3 / mol.
