Key value for chemical safety assessment

Additional information

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 atmospere 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 ist expected either.
