Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Results and discussion

Any other information on results incl. tables

OECD SIDS (2005):

 

The distribution coefficient of phthalimide between aqueous solutions and air was calculated using the Bond-method. The Henry¿s law constant (HLC) was 0.00103 Pa m3/mol at 25 °C.Using the characteristic vapour pressure and solubility of phthalimideat 25 °C, and applying the HLC formula (vapour pressure/water solubility), a HLC of 0.00022 Pa m3/mol is obtained (Bayer Industry Services, 2004).

These data indicate that phthalimide is essentially non volatile from aqueous solution according to the criteria of Thomas (1990).
