- [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.
