ABSTRACT:
A process for the preparation of acrylonitrile by the ammoxidation reaction of propylene, characterized by using an oxide type catalyst which contains, as active ingredients, molybdenum, bismuth, iron and at least one element selected from potassium, rubidium and cesium in specifically limited proportions and which may further contain sodium and/or phosphorus. By the use of such a specific catalyst, the selectivity for the desired acrylonitrile is remarkably improved, and there can be attained high yield of the product. In the process of the present invention, the catalyst can maintain a high activity and a high selectivity for a long time, without undergoing attrition. The catalyst is well prevented from sublimation-escaping of the ingredient molybdenum therefrom.
