Description of key information

Additional information

No studies on adsorption are available for methylcyclohexane (CAS No. 108 -87 -2). However, the substance is not expected to sorb significantly to organic matter in soil, sediment, and wastewater solids based on calculated log Koc values of 2.37 and 3.37. Furthermore, Methylcyclohexane exhibits a very high volatilisation potential (HLC = 34300 Pa*m3/mole) as provided by a QSAR estimation.

Fugacity-based multimedia modelling provides basic information on the relative distribution of a chemical between selected environmental compartments (i.e. air, soil, water, sediment, suspended sediment, and biota). A widely used fugacity model is the EQC (Equilibrium Criterion) Level I model. This model requires the input of basic physico-chemical parameters (i.e. molecular weight, melting point, vapor pressure, water solubility, log Kow). Available results of the Mackay Level I environmental distribution model show that methylcyclohexane has the potential to partition primarily to air. This result can be explained by the high volatility of methylcyclohexane.
