FIELD: chemistry.
SUBSTANCE: present invention relates to versions of an ethanol composition for mixing with fuel. In one version disclosed composition contains at least 92 wt% ethanol; from 95 ppm by weight up to 1000 ppm by weight of isopropanol; and n-propanol, where weight ratio of isopropanol to n-propanol is at least 0.5:1. In another version composition contains said components and is obtained by hydrogenating acetic acid in presence of a catalyst to form a crude ethanol product, containing ethanol, isopropanol and one or more impurities and separation of at least part of crude ethanol product to remove one or more impurities and extract ethanol composition.
EFFECT: mixing ethanol with fuel.
