Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 273-265-5 | CAS number: 68955-28-2 A complex combination of hydrocarbons produced by the distillation of products from a thermal cracking process. It consists of hydrocarbons having a carbon number predominantly of C4.

Administrative data
Description of key information
Members of the category are not expected to hydrolyse based on a lack of hydrolysable functional groups. However, according to Atkinson (1985), the kinetic rate constant for the reaction of members of the category with OH radicals is therefore considered to be from 2.53E-12 to 6.68E-11 cm3/mol/s, indicating that the atmospheric half-life would be in the range of 0.24 to 6.3 days. Overall, members of this category are expected to mainly distribute to the atmosphere when released to the environment, where they are expected to be rapidly degraded through photooxidative reaction mechanisms.
Additional information
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.
