Title:
2-BUTANOL PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2005/108593
Kind Code:
A1
Abstract:
The inventive method for producing 2-butanol by enzymatic catalysed reduction of a 2-butanone with a carbonyl reductase and a coenzyme consists in bringing an aqueous carbonyl reductase-containing phase into contact with a coenzyme in order to reduce the 2-butanone with an alcohol phase which is not mixable with the aqueous phase and contains the 2-butanone, provided that alcohol which is present in the alcoholic phase is a secondary alcohol capable to regenerate the coenzyme and has a boiling point greater than a water boiling point, the thus produced 2-butanol being afterwards separated.
