Web2 apr. 2024 · Microwave-assisted synthesis has become commonplace these days as a means of reducing reaction times and thus increasing the efficiency of the reaction from an energy consumption point of view. 24, 25 We have, therefore, explored microwave-assisted reaction conditions and the results are listed in Table 2. Web30 sep. 2024 · Abstract We report for the first time 100% benzyl alcohol yield from the liquid phase (T = 353 K, P = 9 bar) hydrogenation of benzaldehyde over Au/Al2O3. Under the same reaction conditions, a benchmark Pt/Al2O3 catalyst promoted the formation of toluene and benzene as hydrogenolysis by-products. Reaction kinetics was subjected to a …
