Abstract:
1. Process for the production of acetic acid comprising the steps of: (a) passing a feed stream containing ethanol and water together with a predetermined feed rate of an oxygen containing atmosphere in presence of one or more catalysts being active in simultaneous non-oxidative and oxidative conversion of ethanol to a product stream with acetic acid at a temperature between 250-450° C. and in vapor phase according to the following reaction: wherein x is the molar ratio of oxygen to ethanol, y is the molar ratio of water to ethanol and wherein y is at least (1−2x); and (b) recovering from the product stream a stream of acetic acid; wherein the feed rate of the oxygen containing atmosphere corresponds to a molar ratio of oxygen to ethanol is between 0.0045 and 0.25, and wherein the molar ratio of water to ethanol is at least 0.5.
