Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

The organic carbon-water partitioning coefficient (Koc) calculated from the octanol-water partition coefficient (log Kow = 1.48) using the equation from the TGD (predominantly hydrophobics) is 19.9 l/kg (log value = 1.30). This predicted value is used in the assessment.

Using a Level I fugacity model, the theoretical distribution of ETBE based on physico-chemical properties between four environmental compartments at equilibrium can be calculated. The results in indicate that 96.2% is distributed to the atmosphere and that volatilisation may be expected from water and soil and adsorption to particulate matter is poor.
