Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 293-263-8 | CAS number: 91053-01-9 A complex combination of hydrocarbons obtained from distillation of the butadiene-free C4 fraction of a naphtha steam-cracking process. It consists predominantly of olefinic hydrocarbons having carbon numbers of C8, C12, C16 and C20 and boiling in the range of approximately 170°C to 185°C (338°F to 365°F).

Description of key information
The auto-ignition temperatures of this category have been measured in the range 215°C (C12) - 220°C (C16).
In a guideline, proprietary study (Evonik Oxeno 2008) the auto ignition temperature for tributene was measured as 215°C. This study is non-GLP but follows a standard guideline and is considered reliable and suitable for use as a key study for this endpoint. A supporting study (Aqura2006) reported the auto ignition temperature of tetrabutene to be 220°C. This data is considered to be representative of the category.
The mean of the auto-ignition temperature values for the category is 217.5°Cand this has been used to complete the 'key value for chemical safety assessment'.

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.
