2019年4月9日 · On an oxygen precovered Pd–Au surface, acetaldehyde is selectively oxidized to acetic acid from 250 to 340 K. Using FT-IR, the formation of acetate species is detected from 160 to 260 K on this surface, which is a widely known adsorbate derived from …

When taken up by the organism, acetaldehyde is metabolized rapidly in the liver to acetic acid. Only a small proportion is exhaled unchanged. After intravenous injection, the half-life in the blood is approximately 90 seconds.

But what can turn acetaldehyde into acetic acid? I checked: $\ce{NaOH}$ would turn it into sodium acetate, $\ce{CuO}$ would not react (you'd need $\ce{Cu(OH)2}$), ethanol would turn it into either an acetal or hemiacetal.

2015年10月1日 · In this study, therefore, a Pt/CeO 2 –ZrO 2 –SnO 2 /γ-Al 2 O 3 catalyst was prepared for the selective oxidation of acetaldehyde to acetic acid in water. In this catalyst, the main oxidation catalyst is Pt and γ-Al 2 O 3 is a catalyst support.

It has now been found surprisingly that this residue may be reused as a catalyst by submitting the crude acetic acid formed in the reaction and containing generally of from 1 to 10% of...

1992年1月1日 · The acetaldehyde oxidation process is one of the important steps of acetic acid production. The reaction takes place in a multistage bubble column and the reaction mechanism is very complicated involving gas-liquid mass transfer, hydrodynamics and other factors, and a set of series-parallel reactions.

2015年10月1日 · Pt/CeO2-ZrO2-SnO2/γ-Al2O3 catalysts were prepared by co-precipitation and wet impregnation methods for catalytic oxidation of acetaldehyde to acetic acid in water. In the present catalysts, Pt and CeO2-ZrO2-SnO2 were successfully dispersed on the γ-Al2O3 support.

A method of producing acetaldehyde hydrogenates acetic acid in the presence of an iron oxide catalyst containing between 2.5 and 90 wt % Pd, more preferably 10 and 80 wt % Pd and most...
