Method for the preparation of unsaturated carboxylic acid with high activity phosphomolybdic acid based catalysts |
| abstract |
The present invention relates to a method for the preparation of phosphomolybdic acid based catalysts utilized in the oxidation of aldehydes to unsaturated carboxylic acids by forming a solution of hydrated phosphomolybdic acid in a substantially anhydrous alkanol, adding a base to the solution, evaporating the solution to yield a catalyst powder and thereafter drying and calcining the powder to form the active catalyst. A second method for preparation is also provided and includes the steps of forming a solution of hydrated phosphomolybdic acid in a substantially anhydrous alkanol, evaporating the solution to form a concentrate, impregnating a catalyst support material with the concentrate, contacting the impregnated support with ammonia gas in an amount sufficient to form an insoluble precipitate of ammonium alkyl phosphomolybdic acid within the pore structure of said support material and thereafter drying and calcining said impregnated support material so as to form a coated catalyst. |
