1The effect of hydrogen bond acceptor properties of ionic liquids on their cellulose solubility显示文摘It is nowadays well-known that ionic liquids can dissolve cellulose. However, little systematic data has been published that shed light onto the influence of the ionic liquid structure on the dissolution of cellulose. We have conducted 1H NMR spectroscopy of ethanol in a large number of ionic liquids, and found an excellent correlation of the data obtained with the hydrogen acceptor properties (β-values). With this tool in hand, it is possible to distinguish between cellulose-dissolving and non-dissolving ionic liquids. A modulating effect of both, the anion of the non-dissolving ionic liquid and its cation was found in solubility studies with binary ionic liquid mixtures. The study was extended to other non-dissolving liquids, namely water and dimethylsulfoxide, and the effect of the cation was also investigated.STARK Annegret SELLIN Martin ONDRUSCHKA Bernd MASSONNE Klemens 2012Science China Chemistry2012,55,8:2
2Liquid Phase Hydrogenation of Benzalacet0phen0ne:Effect of Solvent,Catalyst Support,Catalytic M etal and Reaction Conditions显示文摘Innovative catalysts based on a 'porous glass' support material were developed and investigated for the reduction of benzalace-tophenone. The easy preparation conditions and possibility to use different metals (e.g. Pd, Pt, Rh) for impregnation gave a broad variety of these catalysts. Hydrogenation experiments with these supported catalysts were carried out under different hydrogen pressures and temperatures. Porous glass catalysts with Pd as the active component gave chemoselective hydrogenation of benzalacetophenone, while Pt- and Rh-catalysts tended to further reduce the carbonyl group, especially at elevated hydrogen pressures and temperatures. Kinetic analysis of the reactions revealed these had zero order kinetics, which was independent of the type of porous glass support and solvent used.Achim STOLLE Christine SCHM?GER Bernd ONDRUSCHKA Werner BONRATH Thomas F.KELLER Klaus D.JANDT 2011催化学报2011,32,8:1
