Additional information

The partial vapour pressure of peracetic acid for 20°C as reported in the literature is 14.1 hPa (Swern, 1970). The overall vapour pressure of the representative product “Peracetic acid 15%” is 17 hPa when determined according to according to OECD guideline 104 (Mekelburger, 2007). The vapour pressure of peracetic acid at a concentration of 20% and 38% at 20 °C was found to be 18 hPa and 26 hPa, respectively (Turunen, 1996).
