Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
From the water surface, 4-tert-butylcyclohexyl chrloroformate will rapidly evaporate into the atmosphere. The hydrolysis product 4-tert-butylcyclohexanol will slowly evaporate into the atmosphere.
Key value for chemical safety assessment
Additional information
A high Henry's Law Constant (HLC) of 1350 Pa m³/mol was estimated for 4-tert-butylcyclohexyl chloroformate (BASF SE, 2008). However, it is hydrolysed to 4-tert-butylcyclohexanol, CO2 and HCl. The HLC for 4-tert-butylcyclohexanol was estimated to be 1.54 Pa m³/mol, indicating slow volatilization from surface waters (BASF SE, 2009).
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.
