FIELD: chemistry.
SUBSTANCE: subject of present invention is a novel method of producing olefins which is characterised as a cheap industrial process of producing olefins by direct reaction of a ketone and hydrogen in a single step. In particular, described is a novel method of producing olefins, wherein propylene is obtained with high selectivity by direct reaction of acetone with hydrogen. The method of producing olefins provided by the present invention involves reaction of a ketone and hydrogen in the presence of at least one dehydration catalyst and a silver-containing catalyst. The dehydration catalyst is selected from metal oxide catalysts which contain at least one group 6 (VIB) element, zeolites, aluminium oxides and salts of heteropoly acids wherein some or all protons in the heteropoly acids are replaced with metal cations.
EFFECT: providing a method of producing olefins.
