Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The publication by Sander (2015) compiles a number of measured values for the Henry's Law Constant of CFC-12 expressed as solubility in mol/m3.Pa.

Henry's Law volatility constant KH is obtained as 1/Hcp

Henry solubility (defined as c/p) mol /m3.Pa for water as solvent
