TLDR
Ethanol is produced from acetic acid using an olefin having at least 4 carbon atoms, hydrogenating the ester obtained into ethanol, removing the ethanol, dehydrating the higher alcohol back to the original olelin and recycling the olein to esterify the acetic acids as mentioned in this paper.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.read more
