Yield:127-17-3 95%

Reaction Conditions:

with oxygen in water at 100; under 750.075 Torr; for 5 h;Reagent/catalyst;

Steps:

4-6 [Example 4]

Activated carbon supported nano-magnesia catalyst oxidizes lactic acid to produce pyruvic acid. 100 g of lactic acid was placed in the reaction vessel, and then 1 g of the activated carbon-supported nano-magnesia catalyst prepared in Example 1 was added, and oxygen was charged to 0.1 MPa, and the temperature was raised to 100 ° C under constant stirring for 5 hours. If the oxygen partial pressure drops, oxygen is added, and the pressure for maintaining oxygen is about 0.1 MPa. After the reaction was completed, it was cooled to room temperature. Product analysis using gas chromatography,The yield of methyl pyruvate was 95%.
