Abstract:
The present invention provides a method for preparing unsaturated aldehydes and/or unsaturated fatty acids from olefins using a fixed-bed catalytic partial oxidation reactor, in particular, a start-up method upon packing with catalysts and initiating the reaction, and a process for producing unsaturated aldehydes and/or unsaturated fatty acids with high yield.
