          • [Wiley數據庫][2011] Catalytic Conversion of Carbohydrates into 5-Hydroxymethylfurfural by Germanium(IV) Chloride in Ionic Liquids
          • 更新時間:2016-01-20;信息類型:期刊文章
          • Direct conversion of carbohydrates into 5-hydroxymethylfurfural (HMF) catalyzed by germanium(IV) chloride in ionic liquids has been investigated in search of an efficient and environmentally friendly process. Monosaccharides d-fructose and d-glucose, disaccharides sucrose and maltose, and even the polysaccharide cellulose were successfully converted into HMF with good yields under mild conditions (yield up to 92% in 5 min in the case of fructose). The structure of ionic liquids,catalyst loading, reaction temperature and water content had noticeable effects on this catalytic system. Addition of 5 molecular sieves during the dehydration of glucose resulted in an increase in HMF yield from 38.4% to 48.4%. A mechanism for glucose conversion to HMF catalyzed by germanium(IV) chloride was proposed according to 13C NMR spectra obtained in situ under different conditions using d-glucose-2-13C as the substrate.

          • Driving towards success with biomass-derived petrol
          • 更新時間:2014-11-10;信息類型:國內研究進展
          • Chinese scientists have overcome previous limitations to generate high octane number petrol from biomass-derived γ-valerolactone (GVL), an organic compound that is already often blended in small amounts with petrol or diesel. Using an ionic liquid catalyst, the conversion churned out a 2,2,4-trimethylpentane-rich substance with an octane number of 95.4, the highest reported for biomass derived fuel.

          • 更新時間:2014-04-14;信息類型:工業應用>成功案例
          • 中國科學院蘭州化學物理研究所系統研究了以氨基甲酸酯和一氧化碳為羰源合成N-取代氨基甲酸酯并經熱裂解制異氰酸酯過程,形成多個優良的催化劑。通過共沉淀-焙燒-還原的方法發展出磁性四氧化三鐵負載納米鎳催化劑(Ni/Fe3O4),高效的實現了甲苯二胺、4,4'-二苯氨基甲烷二胺、異佛爾酮二胺等為原料制備相應的N-取代氨基甲酸酯。通過系統表征,揭示出納米態Fe-Ni 合金是可能的活性組分,同位素示蹤反應和機理研究發現N,N’-二取代脲是反應的中間體。
