    摘要： Catalytic reactions are taught using air or oxygen for oxidative chemical conversion of primary alcohols to aldehydes and for secondary alcohols to ketones in a vapor phase at ambient pressure. The catalytic process converts ethanol to acetaldehyde, n-propanol to propionaldehyde, 2-propanol to acetone, and other alcohols to aldehydes and ketones. The catalysts are based on molecular strings of di-, tri- and/or poly-groups of transition metal complexes possessing a specific degree of symmetry. Laboratory results have demonstrated [vanadium (II)]2, [chromium (II)]2, [manganese (II)]2, [cobalt (II)]2 oxalate and symmetric transition metal catalysts to be effective for oxidative catalytic conversion of primary alcohols to products comprising related aldehydes and secondary alcohols to products comprising ketones.

    摘要： The invention discloses a method for producing acetaldehyde and/or acetic acid, according to which method a gaseous flow, containing molecular oxygen, ethanol and at least one impurity selected from sulphur compounds, is brought into contact at a high temperature with a sulphur-resistant oxidation catalyst. The ethanol is preferably obtained from a biomass. Said sulphur-resistant oxidation catalyst comprises, for example, vanadium oxide and at least one oxide of zirconium, titanium and aluminium. In one embodiment, the gaseous flow is converted, on the sulphur-resistant oxidation catalyst, into a first oxidation mixture, acetaldehyde being the predominant oxidation product, and said first oxidation mixture is converted, on another oxidation catalyst, into a second oxidation mixture, acetic acid being the predominant oxidation product. Said other oxidation catalyst comprises, for example, a multi-metal oxide containing at least molybdenum and vanadium.
