Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
The substance does not evaporate from the water phase in the atmosphere.
Key value for chemical safety assessment
Additional information
The Henry's Law constant was calculated based on vapour pressure, molecular weight and water solubility.
The vapour pressure of 1-Ethyl-3-methylimidazolium Ethyl Sulfate (CAS 342573-75-5), a chemical comparable to 1-Ethyl-3-methylimidazolium Dicyanamide, was determined to be < 1E-6 hPa at 20 °C. Therefore, a similar vapour pressure is assumed in this calculation for 1-Ethyl-3-methylimidazolium Dicyanamide, as the sole difference between these substance is the composition of the inorganic moiety. The water solubility of the substance itself was determined to be miscible with water in any ratio at 20 °C; for the calculation a water solubility of 10 g/L was used. Based on these parameters, the Henry's Law constant was calculated to be ca. 4.87E-3 Pa·m3/mol.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
