甲基乙烯基酉同类(MVK ) 是广泛地在许多地里被使用了的一种高值的化学药品。在这份报纸,它从生物资源的 levulinic acida 水解作用产品的氧化被形成。在铈二氧化物(CuO/CeO2 ) 和氧化铝(CuO/Al2O3 ) 上支持的铜氧化物被准备并且为 levulinic 酸(LA ) 的氧化使用了。氧化剂借助于 X 光检查衍射(XRD ) 被描绘, H2 温度规划了减小(H2-TPR ) 和原子力量显微镜(AFM ) 技术。CuO/CeO2 和 CuO/Al2O3 关于纯 CuO 显示出不同行为。实验表明 CuO/CeO2 和 CuO/Al2O3 能氧化 LA 并且得到甲基乙烯基酉同类[15.5% 的产量由头空间气体用色层法分离团分光计(HS-GC-MS ) 检测了] 在温和反应条件下面,当纯 CuO 氧化时生产 butanone (MEK ) 的 LA。
Methyl vinyl ketone (MVK) is a kind of high-value chemical which has been widely used in many fields. In this paper, it is formed from oxidation of levulinic acid--a hydrolysis product of biomass. Copper oxide supported on cerium dioxide (CuO/CeO2) and alumina (CuO/AI203) were prepared and used for the oxidation of levulinic acid (LA). The oxidants were characterized by means of X-ray diffraction (XRD), H2-temperature programmed reduction (H2-TPR) and atomic force microscope (AFM) techniques. CuO/CeO2 and CuO/A1203 show a different behav- ior with respect to pure CuO. The experiments revealed that CuO/CeO2 and CuO/AI203 can oxidize LA and get methyl vinyl ketone [yield of 15.5% detected by head space-gas chromatograph-mass spectrometer (HS-GC-MS)] under mild reactive conditions, while pure CuO oxidizes LA to produce butanone (MEK).
