Additional information

Water solubility of tetrahydrophthalic acid, as from the hydrolysis of tetrahydrophthalic anhydride, has been investigated in accordance with OECD/EU test methods and determined to be 43.8 g/L at 20°C and pH 2.3.

The water solubility as function of pH was estimated taking account of the dissociation of this acid.
