Hydrazine hydrate and organosolv synergetic pretreatment of corn stover was developed. With the aid of alkaline and reductive hydrazine hydrate, a high delignification rate (77.94%) and total sugar yield of 90.27% (96.60% glucose, 78.82% xylose) based on the pulp could be obtained using hydrazine hydrate (10 mmol/g corn stover) and aqueous ethanol (60 vt%) as the solvent system. Analysis techniques such as FT-IR, SEM, XRD, and NMR were employed to characterize the structure and property changes of stock before and after pretreatment to evaluate the effect of hydrazine hydrate. A mechanism is proposed for the presented system.
开发了水合肼和有机溶剂协同预处理玉米秸秆的方法。在碱性和还原水合肼的辅助下，使用水合肼（10 mmol/g 玉米秸秆）和 60%体积分数的乙醇水溶液作为溶剂体系，可以获得 77.94%的高脱木质素率和 90.27%的总糖得率（基于纸浆：96.60%葡萄糖，78.82%木糖）。采用 FT-IR、SEM、XRD 和 NMR 等分析技术对预处理前后原料的结构和性能变化进行了表征，以评估水合肼的效果。提出了该体系的一种作用机制。
