Hydrogenation of ethyl acetate on Re/. gamma. -A1/sub 2/O/sub 3/ catalyst
This paper presents a study of the catalytic properties of 5% Re/gamma-A1/sub 2/O/sub 3/ contact in the hydrogenation reaction of ethyl acetate (EA). To clarify the paths of formation of the by products, experiments were also carried out with ethanol under the conditions of hydrogenation of EA. It is shown that the main product of the hydrogenation of EA is ethanol. In addition, Et/sub 2/O, water, and traces of acetaldehyde were found in the catalyzate. In the range of conditions studied, the maximal conversion of ethyl acetate into ethanol is 49%. Increase in the temperature and molar ratio, and also decrease in pressure leads to a decrease in the selectivity of hydrogenation of ethyl acetate into ethanol. Byproducts of the hydrogenation of ethyl acetate - diethyl ether and hydrocarbons - are formed not only as a result of dehydration of ethanol on gamma-A1/sub 2/O/sub 3/, but also directly from ethyl acetate (diethyl ether) and also by the hydrogenolysis of the C-O bond in ethanol on rhenium (hydrocarbons).
