| Abstract: | Pyruvic acid is an important intermediate used in the synthesis of organic and pharamacal products. In this article, highly valued pyruvic acid was synthesized via the oxidative dehydrogenation of low-cost lactic acid catalyzed by Mo-V-Nb multi-component oxides at a low temperature. The phase composition and morphology were investigated by X-ray diffraction (XRD) and scanning electron microscope (SEM) respectively. The reaction products were analyzed by gas chromatograph mass spectrometer (GC-MS) and plausible reaction pathway was proposed. The influence of reaction temperature, partial pressure of oxygen and space velocity on the conversion of lactic acid and selectivities of major products were investigated. |
