Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Water solubility data were not available for any of the streams within this Category. However as the category consists of mainly C4 hydrocarbons, data were read across from hydrocarbon C4 substances (CAS numbers 75-98-5: 53.5 mg/L at 25°C, 115-11-7: 263 mg/L at 25°C, 106-98-9: 222 mg/L at 25°C, 25167-67-3: 222 mg/L at 25°C). All information came from a peer reviewed handbook (CRC, 2008) or McAuliffe (1966) who used a non-standard method that was fully reported and deemed suitable for the assessment of water solubility of gases. The water solubility range of this Category was determined to be 53.5 - 263 mg/L.

The mean of the water solubility values for the category is 190.1 mg/L at 25°C and this has been used to complete the 'key value for chemical safety assessment'.
