| titleOfInvention | Production of methacrylic acid |
| abstract | Methacrylic acid is produced by the oxidative carbonylation of propylene by contacting propylene, oxygen and carbon monoxide in the presence of a Group VIII noble metal catalyst containing a redox agent and an alkali metal acetate. Preferably the oxidation is performed in liquid phase comprising a low molecular weight fatty acid as the solvent. In a typical embodiment, the Group VIII noble metal concentration is from 0.001 to 1.0 molar, the concentration of the redox metal is from 0.05 to 0.5 molar, the concentration of the halide anion is from 0.1 to 0.5 molar and the carbon monoxide partial pressure is from 10 to about 70 percent of the total pressure which is from about 300 to 3,000 p.s.i.g. Under these conditions a substantial portion of the product comprises the desired methacrylic acid. |
