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.

Description of key information

Additional information

Diethyl ether (DEE) is not considered to be biodegradable in water. The small Log Koc value indicates that the potential for adsorption to soil and sediment is expected to be low. The vapour pressure and the large Henry's Law constant suggests that, under appropriate conditions, loss of the substance from water bodies and soil to the air will be rapid. As a result, the substance is expected to primarily partition to the atmospheric compartment. It is expected to rapidly degrade in the atmosphere, by hydroxyl radical attack, to form ethyl formate. Hydroxyl attack is also expected to occur in water, though at approximately half the rate (Wallington, T.J. et al, Int. J. Chem. Kinet., 1988, 20, 41 - 49).

Based on the weight-of-evidence, the substance is considered to have low bioaccumulation potential in the aquatic compartment.

The substance is not expected to persist in the environment.
