Estimation of Koc value by EPI Win (Koc Win,
v2.0), by MCI methodology:
Koc = 7.887 L/kg.
The organic-normalized sorption coefficient
for soil (Koc) was predicted with KOCWIN v2.00 and reveals a value of
7.887 L/kg using the MCI method (Chemservice S.A., 2017). This method is
based on the substance specific partition coefficient and includes
improved correction factors. The traditional method showed a value of
4.494 L/kg. Thus, a low binding capacity to soil can be expected for
Butylaminoethanol (according to Freundlich, cited in: "Handbuch des
Bodenschutzes"). In addition, the chemical is considered to be readily
Air water partition coefficient
Henry´s Law constant (HLC) describes the
equilibrium concentration of a dissolved substance in air versus the
dissolved substance concentration found in water. At a constant
temperature, the solubility of a gas in a liquid solution will be
proportional to the partial pressure of the gas which is above the
solution (Henry, 1803). The HLC of Butylaminoethanol was predicted with
HENRYWIN v3.20 (Chemservice S.A., 2017). Two different models are used:
The group method, which splits the compounds into smaller units and the
bond contribution method, which includes individual hydrogen bond values
as well. Assuming a surrounding temperature of 25 °C, the group Method
gives a value of 6.08 E-5 Pa*m³/mol, the bond method results in a HLC of
1.91 E-4 Pa*m³/mol.
