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.
