The conversion of raw biomass into C5-sugars and furfural was demonstrated with the one-pot method using Brønsted acidic ionic liquids (BAILs) without any mineral acids or metal halides. Various BAILs were synthesized and characterized using NMR, FT-IR, TGA, and CHNS microanalysis and were used as the catalyst for raw biomass conversion. The remarkably high yield (i.e. 88%) of C5 sugars from bagasse can be obtained using 1-methyl-3(3-sulfopropyl)-imidazolium hydrogen sulfate ([CSOHMIM][HSO]) BAIL catalyst in a water medium. Similarly, the [CSOHMIM][HSO] BAIL also converts the bagasse into furfural with very high yield (73%) in one-pot method using a water/toluene biphasic solvent system.
使用布朗斯台德酸性离子液体（BAILs）通过一锅法在不添加任何无机酸或金属卤化物的情况下，实现了将生物质原料转化为C5糖和糠醛。合成了多种BAILs，并通过核磁共振（NMR）、傅里叶变换红外光谱（FT-IR）、热重分析（TGA）和元素分析（CHNS）对其进行了表征，并用作生物质原料转化的催化剂。在水介质中，使用1-甲基-3-(3-磺酸丙基)-咪唑硫酸氢盐（[CSOHMIM][HSO]）BAIL催化剂，可从甘蔗渣中获得高达88%的C5糖产率。同样，在水/甲苯双相溶剂体系的一锅法中，[CSOHMIM][HSO] BAIL也能以非常高的产率（73%）将甘蔗渣转化为糠醛。
