| titleOfInvention | An improved method for the selective reduction of propionic acid from a (meth) acrylic acid product stream |
| abstract | An object of the present invention is to provide an improved catalyst for use in reducing PA from an AA stream under oxidizing conditions. As a result, it was unexpectedly found that most selective catalysts in reducing PA from AA streams are the same as mixed metal oxides (MMO) used to produce AA and PA from propane oxidation. It was. Accordingly, it is an object of the present invention to provide a PA reduction catalyst for use in producing high purity AA monomers. The present invention relates to an improved method for the selective reduction of propionic acid (hereinafter “PA”) impurities from an acrylic acid (hereinafter “AA”) stream. [Selection figure] None |
