Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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