Method for preparing pyruvic acid by catalyzing and oxidizing lactic acid in water phase |
| abstract |
The invention discloses a method for preparing pyruvic acid by catalyzing and oxidizing lactic acid in a water phase, which takes lactic acid as a raw material, oxygen or air as an oxidant and supported nano magnesium oxide as a catalyst to prepare pyruvic acid through catalytic oxidation reaction; the catalytic reaction can be carried out under normal pressure, an organic solvent is not needed, the product yield is high, and the catalyst can be recycled. |
