Description of key information

Adsorption to the solid soil phase and evaporation to the atmosphere from water is not expected for the reaction mass                         

Additional information

Due to the predicted log Koc-values < 3 of the single components cyclohexanol (log Koc = 1.05) and cyclohexanone (log Koc = 1.24), adsorption to solid soil phase (e.g. clay) of the mixture is not expected. The values were calculated with the software KOCWIN v2.00, EPI Suite v4.11.


Calculations with the software HENRYWIN v3.10, EPIwin v4.11 for the single components cyclohexanone and cyclohexanol predicted Henry's Law constants (HLC) < 100 Pa m3/mol. Therefore, evapurtion to the atmosphere from water is not expected for the single components. The calculated HLC for cyclohexanone is 5.18 Pa m3/mol and 0.496 Pa m3/mol for cyclohexanol. Values within the same range from literature support the calculated values (for cyclohexanone 1.21 Pa m3/mol; Hawthorne, 1985 and for cyclohexanol 0.00018 Pa m3/mol; Altschuh et al., 1999). Based on these values for the single components no evapuration for the mixture of both to the atmosphere from water is expected either.
