Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Adsorption
The estimated low Koc values of the parent compound and the hydrolysis product indicate no significant potential for adsorption to soils or sediments (US EPA, 2008; OECD, 2005).
Henry's Law Constant
A high Henry's Law Constant (HLC) of 316 Pa m³/mol was estimated for ethyl chloroformate (US EPA, 2008). However, it is rapidly hydrolysed to ethanol, CO2 and HCl.
Based on a calculated HLC of 0.6 Pa m³/mol, ethanol will not evaporate into the atmosphere from the water surface (OECD, 2005).
Distribution
Following the Mackay Level I calculations, the parent compound will preferentially distribute into the air (86.8%) and water (13.2%) (BASF SE, 2008). The hydrolysis product ethanol is expected to preferentially distribute into the compartments air (48.1%) and water (51.9%) (BASF SE, 2008). Mackay Level III calculations reveal that ethanol would predominantly distribute into water (45.8 %) and soil (45.6 %) (BASF SE, 2008).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.
