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. ® KIPO & WIPO 2007
