Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

In soil, dimethyl ether - boron trifluoride reacts readily with the moisture to form dimethyl ether and boron trifluoride dihydrate. Dimethyl ether and boron trifluoride dihydrate are not readily biodegradable, but they have a low potential for adsorption. Dimethyl ether has a logKow of 0.13 - 0.26 (JETOC, 1991). Boron trifluoride dihydrate, as well as its further hydrolysis products (e.g. boric acid, fluoroborates), are inorganic and have no cationic properties. Binding to sewage sludge is therefore unlikely, and as a consequence a transfer to the soil compartment is not expected. No tests on terrestrial organisms are therefore provided.
