Реферат:
The possibility was shown of the activation of the 5% Re/γ-Al2O3 catalyst for the hydrogenation of ethyl acetate directly into ethanol under the experimental conditions (230°C, 30 atm, molar ratio H2;ethyl acetate=5). Thus, deposited rhenium(VII) is reduced to rhenium at lower degrees of oxidation.
In the range of conditions studied, the maximal conversion of ethyl acetate (EA) into ethanol is 49% (selectivity 83.5%), which is observed at 60 atm, 230°C, H2:EA=5, Vmax=0.7 h−1. 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 the result of dehydration of ethanol on Y-Al2O3, but also directly from ethyl acetate (diethyl ether) and also by the hydrogenolysis of the G-O bond in ethanol on rhenium (hydrocarbons).
