CATALYST FOR PRODUCING ALPHA-BETA-UNSATURATED ALDEHYDES, METHOD OF PREPARATION THEREOF, AND METHOD OF ACROLEIN PRODUCTION Russian patent published in 1999 - IPC

FIELD: oxidation catalysts. SUBSTANCE: catalyst for producing alpha-beta-unsaturated aldehydes via oxidation of olefins contains carrier covered with active phase based on bismuth, molybdenum and/or tungsten, cobalt, nickel, iron and oxygen promoted with phosphorus and at least one alkali element. Active phase constitutes 15 to 33% of catalyst weight and atomic ratio of phosphorus and alkali element to active phase equals 100 x (P + alkali element)/Ni = 0.9-10. EFFECT: stabilized catalyst characteristics. 5 cl, 1 dwg, 3 tbl, 9 ex
