Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
The ready biodegradation of “2-propanol and 2-butanol production, distn. residues” (consisting mainly of di-isobutyl ether, di-isopropyl ether, C3- and C4-alcohols and C6-hydrocarbons) was tested according to ISO 14593:2005 under GLP. No significant degradation (14%) of the test item was observed after 28 days. Thus, the “2-propanol and 2-butanol production, distn. residues” are not readily biodegradable.
This finding is corroborated by the degradability of the main constituents of 2-propanol and 2-butanol production, distn. residues: While alcoholic components (SBA, and IPA), making up approximately 15% of the reaction mass, were found to be readily biodegradable, the components DSBE, DIPE, were not readily biodegradable, whereas TBA may be inherently biodegradable.
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.
