Abstract
The process involves esterifying ethanol and acetic acid to produce an esterification product that is in a single phase that is directly reduced, by hydrogenolysis, to produce ethanol. The single phase is not capable of separating. Feeding a single phase feed stream reduces the separation of the esterification product. Hydrogen may be fed to the esterification reactor that operates at a high pressure that is substantially similar to or greater than the hydrogenolysis reactor.
