Phototransformation in air

For the indirect photodegradation of isobutyric acid in air by reaction with OH radicals, a half-life of approx. 167 hours (6.9 days) was calculated (ECT, 2009).



Due to its chemical structure and reactivity, isobutyric acid will not hydrolyze under environmental conditions. The structure of the molecule does not contain hydrolizable constituents (GUBDH, 2008).
