Abstract
Ethanol is produced from acetic acid by esterifying the acetic acid with an olefin having at least 4 carbon atoms, hydrogenating the ester obtained into ethanol and a higher alcohol having at least 4 carbon atoms, removing the ethanol, dehydrating the higher alcohol back to the original olefin and recycling the olefin to esterify the acetic acid.
