ABSTRACT:
A process for the selective production of ethyl acetate by vapor phase reaction of acetic acid over a hydrogenating catalyst composition to form ethyl acetate is disclosed and claimed. In an embodiment of this invention reaction of acetic acid and hydrogen over platinum and copper supported on silica selectively produces ethyl acetate in a vapor phase at a temperature of about 250° C.
