FIELD: chemistry.
SUBSTANCE: present invention relates to vanadium-titanium oxide catalysts, used in production of methonic acid through gas-phase oxidation of formaldehyde with oxygen and methods of obtaining methanoic acid using the said catalysts. Description is given of a catalyst containing 7.0-50.0 wt % vanadium oxide and modifying compounds: one or more oxides of group IV and V metals with total weight content of oxides of modifying metals between 0.1 and 10.0 wt %, and mainly between 0.1 and 3 wt %. Described also is a method of obtaining methanoic acid through oxidation of formaldehyde using oxygen in one or several serial pipe reactors in the presence of the above described catalyst.
EFFECT: increased catalyst activity and increased output of methanoic acid.
