摘要

生物质转化复杂混合物的组分分析和结构表征仍然是一项具有挑战性的工作。因此,开发有效且易于使用的技术是必要的。扩散有序核磁共振波谱(DOSY)是一种非选择性和非侵入性的方法,能够通过提供组分的扩散系数(D)来实现生物质混合物中单个化合物的伪分离和结构分配。然而,当分析含有相似化学结构的复杂混合物时,传统的1H-DOSY NMR受到拥挤共振的限制,从而导致相似的系数。在此,我们描述了一种先进的扩散NMR方法——CHirp激发DOSY产生的纯位移(PSYCHE iDOSY)的应用,该方法可以记录高分辨率的信号扩散光谱,有效地将模型和真实混合物样品中的化合物与纤维素、半纤维素和木质素分离。在扩散维度上成功分离了复杂的异构体(d-葡萄糖/d-果糖/d-甘露糖和1,2-/1,5-戊二醇)、同源化合物(乙二醇和1,2-丙二醇)、木质素的模型化合物和真正的反应体系(开环糠醇氢解)。结果表明,超高分辨率DOSY技术能够检测和伪分离木质纤维素生物质中C5/C6糖转化产物及其衍生物加氢/氢解的混合组分。

NMR diffusion analysis of catalytic conversion mixtures from lignocellulose biomass using PSYCHE-iDOSY

The component analysis and structure characterization of complex mixtures of biomass conversion remain a challenging work. Hence, developing effective and easy to use techniques is necessary. Diffusion-ordered NMR spectroscopy (DOSY) is a non-selective and non-invasive method capable of achieving pseudo-separation and structure assignments of individual compounds from biomass mixtures by providing diffusion coefficients (D) of the components. However, the conventional 1H DOSY NMR is limited by crowded resonances when analyzing complex mixtures containing similar chemical structure resulting in similar coefficient. Herein we describe the application of an advanced diffusion NMR method, Pure Shift Yielded by CHirp Excitation DOSY (PSYCHE-iDOSY), which can record high-resolution signal diffusion spectra efficiently separating compounds in model and genuine mixture samples from cellulose, hemicellulose and lignin. Complicated sets of isomers (d-glucose/d-fructose/d-mannose and 1,2-/1,5-pentadiol), homologous compounds (ethylene glycol and 1,2-propylene glycol), model compounds of lignin, and a genuine reaction system (furfuryl alcohol hydrogenolysis with ring opening) were successfully separated in the diffusion dimension. The results show that the ultrahigh-resolution DOSY technique is capable of detecting and pseudo-separating the mixture components of C5/C6 sugar conversion products and its derivative hydrogenation/hydrogenolysis from lignocellulose biomass.
