Additional information

Limit value: The vapour pressure study does not need to be conducted as the melting point is between 200 °C and 300°C.

The Vapour pressure of Isatoic acid anhydride as result from an experimental study from BASF resulted to be 0,0005 hPa 108,7°C. The vapour pressure at 20 °C calculated from this regression equation resulted to be 0,0000000097 hPa.

Therefore the estimated vapour pressure for Isatoic acid anhydride at 20°C is below the limit value of 10E-5 Pa.
