Propionic acid, puriss. p.a., >=99.5% (GC)

InChI=1/C3H6O2/c1-2-3(4)5/h2H2,1H3,(H,4,5

A pKa of 4.87(1) indicates propionic acid will exist almost entirely in the anion form at pH values of 5 to 9 and therefore volatilization from water surfaces is not expected to be an important fate process(2). Propionic acid is expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure of 3.35 mm Hg(3).

NY, NY: Am Inst for Phys Prop Data (1985)

The Koc of propionic acid is estimated as 36(SRC), using a log Kow of 0.33(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that propionic acid is expected to have very high mobility in soil. The pKa of propionic acid is 4.87(4), indicating that this compound will primarily exist in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5).
