Description of key information
Additional information
The distribution of phthalic anhydride between the organic phase of soil or sediments and the porewater was calculated by using QSAR with the PCKOC program (v 1.66). A Koc of 11 for phthalic anhydride (Bayer Industry Services, 2004a) was calculated. Von Oepen (1991) investigated the sorption capacity of three different soils by batch equilibrium studies for the hydrolysis product phthalic acid similar to the OECD TG 106 . The soils used for testing were an acidic forest soil, an agricultural soil and a sublimnic soil. The sorption equilibrium was reached within 16 hours. Sorption coefficients between 2 and 31 were determined.
The Henry's law constant (HLC) of phthalic anhydride is estimated as 0.64 Pa m³/mol at 25 °C (Bayer Industry Services, 2004). For the hydrolysis product of the phthalic anhydride, phthalic acid, the HLC is estimated as 2.21 x 10-7 Pa m³/mol (Bayer Industry Services, 2004).
Calculation of the distribution of phthalic anhydride in the environment according to the Mackay fugacity model, is not suitable because the substance hydrolyses rapidly in water. The Mackay model does not consider degradation reactions, hence the Mackay equilibrium distribution of phthalic anhydride in the environment is not appropriate.
The distribution of the hydrolysis product phthalic acid in a "unit world" was calculated according to the Mackay fugacity model level I (Bayer Industry Services, 2004) based on the physico-chemical properties. The main target compartment for phthalic acid is water with 99.91 %, followed by soil and sediment with 0.042 and 0.043%, respectively.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
