Abstract
A process for the preparation of unsaturated nitriles from olefins, in the presence of a catalyst based on antimony, tin, tungsten, copper and tellurium, whose process consists of: a) said catalyst is prepared by making the precipitation separately or simultaneously from of salts or soluble compounds of antimony, tin, tungsten, copper and tellurium and/or by simultaneously or separately thermal decomposition of the compounds convertible into oxides of the aforementioned elements, by heating, to obtain an intimate combination of the oxides of said elements; b) subject to heat treatment, at a temperature between 500 and 1000ºC and in an oxygenated atmosphere, the catalyst from step a), to obtain a compound of the formula: sba snb wc cud tee of in which, a between 1 and 10, b between 1 and 10, c between 0.01 and 5. d between 0.01 and 5, e between 0.01 and 5 and f is the number of oxygen atoms of the obtained oxygen combination. combining the metallic elements of formula (1). C) subjecting an ammoxidation reaction, with oxygen and ammonia as reagents, in the presence of the catalyst from step b), an olefin to obtain the corresponding unsaturated nitrile.
