Abstract: Catalyst for the oxidation of C3-4, olefins to unsatd. aldehydes consisting of a mixture of silicon dioxide with the oxides of molybdenum oxide, bismuth oxide and, if desired, phosphorum oxide is prepared by converting a silicon-oxygen compound into the gas phase and introducing precursors for the oxides of molybdenum, bismuth and phosphorus into the gaseous silicon-oxygen compound. The precursors are atomised through a fine nozzle and introduced into the gaseous compound at above 1000 deg.C, preferably above 1400 deg.C. Silicon dioxide, silicon monoxide or a mixture of these oxides may be used as the silicon-oxygen compound. Preferably oxygen or air is supplied with the molybdenum, bismuth and phosphorus precursors.
