TLDR
Ethanol is prepared by hydrogenating acetic acid under superatmospheric pressure and at elevated temperatures by a process wherein a predominantly cobalt-containing catalyst is used and acetic acids and hydrogen are passed through the reactor, at from 210° to 330° C. and under conditions such that a liquid phase in not formed during this procedure.Abstract:
Ethanol is prepared by hydrogenating acetic acid under superatmospheric pressure and at elevated temperatures by a process wherein a predominantly cobalt-containing catalyst is used and acetic acid and hydrogen are passed through the reactor, at from 210° to 330° C. and under from 10 to 350 bar, under conditions such that a liquid phase in not formed during this procedure.read more
