Results and discussion

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).
