PRODUCTION OF ACROLEIN OR ACRYLIC ACID AND CATALYST USED FOR THE SAME

Title:

PRODUCTION OF ACROLEIN OR ACRYLIC ACID AND CATALYST USED FOR THE SAME

Document Type and Number:

Japanese Patent JP3328340

Kind Code:

B2

Abstract:

PURPOSE: To obtain a catalyst for producing acrolein and/or acrylic acid from propane at high activity and a high selectivity by using a heteropolyacid or the salt containing phosphorus and molybdenum as essential components.
CONSTITUTION: The heteropolyacid or the salt containing phosphorus and molybdenum as the essential component is used as the catalyst for producing acrolein and/or acrylic acid by allowing propane to react with molecular oxygen. The general formula of the catalyst is PaMobVcAdXeOx (where, A is arsenic and/or antimony, X is tin, Pb or the like and when (b) is 12, (a) is 0.5-3, (c) is 0.01-3, (d) is 0-3, (e) is 0-3, (x) is a number fixed by the oxidizing state of each structural element).
