Phototransformation in air:

The atmospheric oxidation half-life of diiodohydroxyquinoline was estimated using the level III multimedia model. It was estimated that the substance is not persistent in air medium as the half life period of diiodohydroxyquinoline in air is 1.8 days. This indicates that diiodohydroxyquinoline is easily phototransformed in air.


The Hydrolysis rate constant of diiodohydroxyquinoline is estimated to be 0.0000000000088062 (8.8062 E-12) cm3/molecule-sec. at half life of the 14.575 hrs. The estimated half life of the substance indicates that the substance is moderately hydrolysable.
