摘要
The present invention relates to a method for the preparation of phosphomolybdic acid based catalysts by forming a solution of hydrated phosphomolybdic acid in a substantially anhydrous alkyl alcohol, heating the solution to form a concentrate, and thereafter drying and calcining the concentrate support material so as to form the catalyst. Because the catalyst is prepared in alcoholic rather than aqueous solution, it has a greater activity in converting aldehydes to their respective unsaturated carboxylic acids than known phosphomolybdic acid based catalysts. Furthermore, the deammoniation step of the prior art is no longer required.
