Chemicals from ethanol—The acetone one-pot synthesis

Elimination of acetaldehyde from hydrogen rich streams employing Ni/ZrO2

“…These results agree with the findings of Rodrigues et al [19], who proposed that as ZrO 2 shows superficial O mobility, it is able to oxidize acetaldehyde to acetate species.…”

“…4a and b). This occurs due to the adsorption of acetaldehyde on the ZrO 2 sites, as already observed by Rodrigues et al [19] and Zonetti et al [15]. However, the Ni/ZrO 2 FTIR spectra show slightly higher intensity when compared with the ones of Ni/SiO 2 .…”

The role of m-ZrO2 in the selective oxidation of ethanol to acetic acid employing PdO/m-ZrO2

“…This condensation occurs assisted by strong basic sites of m-ZrO 2 . This work shows that m-ZrO 2 is able to oxidize acetaldehyde to acetate species and promote the ketonization reaction [7].…”

“…Rodrigues et al [7] proposed the following mechanism: firstly, ethanol is adsorbed on m-ZrO 2 and Cu, generating ethoxides species. These species adsorbed on m-ZrO 2 spillover to Cu catalyst, and then acetaldehyde is synthesized by dehydrogenation.…”

“…It can generate many different chemicals, including ethyl acetate [1][2][3][4], 1-butanol [5,6], acetone [7], propene [8], isobutene [9], 1,3 butadiene [10] in a one-pot reaction employing multifunctional catalysts.…”
