    用于生物质加工的两亲性和相分离离子液体
    摘要:
    使用离子液体(IL)的未来生物过程的技术经济学的一个主要限制因素是昂贵且潜在有毒的IL的回收。我们已经证明了一系列基于疏水四烷基alkyl阳离子([ PRRR ] +)的可相分离的离子液体,该液体可以以纯净状态溶解木质素,但也可以以电解质溶液的形式溶解半纤维素和高纯度纤维素。与偶极非质子溶剂一起使用。例如,IL三辛基甲基乙酸acetate([P 8881[OAc])在添加40 wt%的DMSO的情况下,在60°C时最多可溶解19 wt%的微晶纤维素(MCC)。发现MCC饱和点取决于溶液中DMSO和IL的摩尔比。在最佳饱和度下,摩尔比约为1:1 [P 8881观察到[OAc]为脱水葡萄糖单元,这表明高效溶剂化。在Lindman假设的背景下,这归因于这些更多的两亲阳离子-阴离子对的积极贡献。MCC上的溶液状态HSQC NMR光谱进一步说明了这种有效的溶解。最后,还证明了通过添加水溶液这些电解质

  • Room-Temperature Copper-Catalyzed Carbon-Nitrogen Coupling of Aryl Iodides and Bromides Promoted by Organic Ionic Bases
    作者:Chu-Ting Yang、Yao Fu、Yao-Bing Huang、Jun Yi、Qing-Xiang Guo、Lei Liu
    DOI:10.1002/anie.200903158
    日期:2009.9.21
    solubility alone does not explain the performance of organic ionic bases in the roomtemperature coupling of aryl iodides and even bromides with aliphatic and aromatic amines and N‐heterocycles (NuH; see scheme). Conductivity measurements show that these organic ionic bases, which contain tetraalkylammonium or ‐phosphonium cations, are readily ionized in organic solvents.

  • PEG-functionalized ionic liquids for cellulose dissolution and saccharification

    Cellulose-dissolving ionic liquids (ILs) have become powerful neoteric solvents in the pretreatment of cellulosic biomass for ethanol fuel production. There are, however, a number of challenges to using current ionic solvents at large scales (imidazolium-based salts, in particular), including their relatively high costs and viscosities and their sluggish biodegradability. Aiming to overcome these hurdles, we have prepared a new series of poly(ethylene glycol) (PEG)-functionalized ILs comprising inexpensive alkylammonium or piperidinium cations paired with acetate anions. Some of these new ILs are capable of dissolving 8–12 wt% cellulose, while displaying low viscosities and acceptable thermal stabilities at the required process temperature. Our XRD and SEM data further confirm that regenerative pretreatment of cellulose by these PEGylated ILs can effectively transform the cellulose I structure to cellulose II, reducing the crystallinity of cellulose and increasing the structural homogeneity. Most excitingly, cellulose regenerated from these ILs can be rapidly hydrolyzed to glucose, in ∼90% glucose yield after 2 h, using a commercial cellulase supplemented with β-glucosidase.
    纤维素溶解型离子液体(IL)已成为在生产乙醇燃料的纤维素生物质预处理过程中一种强有力的新型溶剂。然而,使用当前的离子溶剂(特别是咪唑盐类)在大规模应用时面临诸多挑战,包括成本和粘度较高、生物降解性不佳等问题。为了克服这些障碍,我们合成了一系列新型聚乙二醇(PEG)功能化的离子液体,这些离子液体采用廉价烷基铵或哌啶鎓阳离子与乙酸阴离子配对。其中一些新型离子液体能够溶解高达8-12 wt% 的纤维素,并且在所需的工艺温度下表现出低粘度和可接受的耐热性。通过XRD和SEM数据进一步证实,这些PEG化的离子液体对纤维素的再生预处理能够有效将纤维素I结构转变为纤维素II,从而降低纤维素的结晶度并增强结构均匀性。最令人兴奋的是,从这些离子液体中再生出的纤维素可以快速水解为葡萄糖,在添加了β-葡萄糖苷酶的商业纤维酶作用下,2小时后葡萄糖产率可达约90%。

    Here we report the synthesis and application of finely divided Cu2O nanoparticles (Cu2O-NPs) in the range from 5.5 nm to 8.0 nm in phosphonium ionic liquids as the first recyclable and effective catalytic system for smooth, ligand- and additive-free protodecarboxylation of 2-nitrobenzoic acid as a model substrate and further derivatives. The reactions run with low catalyst loadings and result in quantitative yield in ten consecutive recycling experiments. In addition this system is highly selective towards electron-poor 2-nitrobenzoic acids.
