Tin bis(2-ethylhexanoate) (i.e.,Stannous
Octoate) is a clear to pale yellow, viscous liquid at typical ambient
temperatures, and is manufactured and used only in this liquid form. The
substance does not boil, as thermal decomposition occurs at temperatures
above approximately 150 °C
in the presence of oxygen. The substance has a relative density of 1.26,
which along with its insolubility in water, causes it to sink as a dense
non-aqueous phase liquid in aqueous media. Once introduced to water, the
substance is known to dissociate into its 2-ethylhexanoate and Sn(II)
components. The measured dissociation constant for the intact salt is
5.09, whereas that for the free acid form of 2-ethylhexanoic acid is
4.8. Whereas the Sn(II) component occurs initially in water as Sn(OH)2,
this species is expected to spontaneously oxidize in oxygenated water to
form the insoluble inorganic solid Sn(IV)O2. The 2 -ethyl
hexanoate component has moderate solubility and low octanol-water
partition coefficient (log Kow = 2.64). These properties result in a low
potential for adsorption to organic matter of soil and sediment. The Tin
bis(2-ethylhexanoate) substance exhibits a high flash point (137 °C),
and high auto-ignition temperature (> 400 °C),
and is therefore regarded as non-flammable liquid. The substance does
not possess atoms or functional groups which are known to contribute to
pyrophoric or explosive properties, and testing has confirmed the lack
of these hazardous properties.
