A pKa of 10.68(1) indicates isobutylamine will exist almost entirely in the cation form at pH values of 5 to 9 and therefore volatilization from water surfaces is not expected to be an important fate process(2). The potential for volatilization of isobutylamine from dry soil surfaces may exist(SRC) based upon a vapor pressure of 138 mm Hg(3).

The Koc of isobutylamine is estimated as 60(SRC), using a log Kow of 0.73(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that isobutylamine is expected to have high mobility in soil. The pKa of isobutylamine is 10.68(4) indicating that this compound will exist almost entirely in the cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5).
