| titleOfInvention | Production method of catalyst precursor for production of α,β-unsaturated carboxylic acid |
| abstract | The present invention provides a catalyst precursor for producing an α,β-unsaturated carboxylic acid capable of producing an α,β-unsaturated carboxylic acid in a high yield. The present invention provides a method for producing a catalyst precursor for the production of α,β-unsaturated carboxylic acid, in which α,β-unsaturated aldehyde is produced by gas-phase contact oxidation of α,β-unsaturated aldehyde using molecular oxygen to produce α,β-unsaturated carboxylic acid A method for producing a precursor of a catalyst to be used, the precursor containing ammonium radicals, the production method having the steps of (i) preparing an aqueous slurry or aqueous solution containing a platinum-containing heteropolyacid (I), (ii) in The process of adding an ammonium compound to the aqueous slurry or aqueous solution (I) to obtain the slurry (II) in which the ammonium salt of the heteropolyacid is precipitated, and (iii) the slurry in which the ammonium salt of the heteropolyacid is precipitated In the step of drying the feed (II) to obtain the precursor, as the ammonium compound in the step (ii), an ammonium compound containing 30% by mass or more of ammonium carbamate is used. |
