Catalyst for aldehyde production

摘要

A catalyst for aldehyde production through selective oxidation of alkanol with oxygen comprises: iron molybdate and molybdenum trioxide wherein the Mo/Fe molar ratio is 1.5-5 and the specific surface area is 1-20 m²/g, the catalyst further comprising phosphorus. The alkanol maybe methanol or ethanol. The catalyst may contain 50-50,000 ppm of phosphorus. A process for producing the catalyst comprises impregnating a solid catalyst comprising iron molybdate and molybdenum trioxide with a solution of a phosphorus containing compound. The catalyst may be calcined after the treating step, or the solid catalyst calcined before the treating step. The solid catalyst may be prepared by a co-precipitation method.
