The Koc value for FBSEE diol was calculated using equation from European
Chemicals Bureau: Technical Guidance Document on Risk Assessment,
Chapter 4, Table 4, page 26.
Predominantly hydrophobics: Log Koc (unitless) = 0.81 logKow + 0.10
Experimental log Kow of FBSEE Diol = 2.7 at 22 °C;
Log Koc (unitless) = 0.81 x (2.7) + 0.10 = 2.3;
Koc (unitless) = 200
partition coefficient (Koc and log Koc ) can be calculated using the
equation from European Chemicals Bureau: Technical Guidance Document on
Risk Assessment, Chapter 4, Table 4, page 26: for predominantly
hydrophobics: Log Koc (unitless) = 0.81 logKow + 0.10, FBSEE diol has an
experimental log Kow of 2.7 at 22 °C. Based on the equation, the
calculated log Koc (unitless) was
2.3, the Koc was 200 (unitless).
