Description of key information
Additional information
The Koc is estimated to be 256 for the neutral and 433 for the protonated form of dicyclohexylamine, respectively (Bayer Industry Services, 2005b).
Soil adsorption coefficient estimated for Dicyclohexylamine (by KOCWIN v 2.00) using the measured log P (log P = 2.724measured at pH 6.7 (Research Institute for Organic Syntheses Inc., 2010)) was Koc = 52.08 L/kg (Kow method).
With an estimated Koc value of 433 for the protonated form, dicyclohexylamine can be regarded as a substance with a moderate potential for accumulation in soil.
The Henry’s Law constant for the neutral form of dicyclohexylamine, calculated with QSAR is 5.57 Pa m³/mol at 25 °C, prove a high potential for volatilization from surface waters. Regarding the Henry’s Law constant for the protonated form of dicyclohexylamine of 4.26 x 10-7 Pa m³/mole, the substance is not expected to volatilize from water.
With a pKaof 10.39 at 25°C, dicyclohexylamine will exist predominantly in its protonated form in the environment. The distribution of the protonated form of dicyclohexylamine in a “unit world” was calculated according to the Mackay fugacity model level I.The main target compartment of dicyclohexylamine is water with 99.71 % (Bayer Industry Services, 2005d).
