The present invention relates to the process of hydrogenating acetaldehyde feedstreams to form an ethanol mixture in the presence of a catalyst. The acetaldehyde feedstream contains acetaldehyde and at least a portion of acetic acid and ethanol. Preferentially, the acetaldehyde feed stream is a by-product stream for the vinyl acetate synthesis process. Jevtic Radmila (US); etc.US2012323048
