liquid reached 37.49%, without any additives. Using B2O3 and CaCl2 as additives, the optimum yield increased to 67.37% at 180 °C in 20 min. In addition, HPLC-MS analysis has been utilized to elucidate the reaction mechanism. This research on turning “waste” into “wealth” opens up new ways for the utilization of biomass waste, which not only reduces environmental pollution but also has potential economic
几丁质及其衍生物含有生物固定的氮元素,可以为含氮化学物质提供氮源。在此,合成了一系列基于吡啶鎓的离子液体,以直接催化N-乙酰基-D-葡糖胺(NAG,几丁质的单体)向3-乙酰氨基-5-乙酰基呋喃(3A5AF)的转化。1-羧甲基吡啶鎓氯化物离子液体中3A5AF的收率达到37.49%,无任何添加剂。使用B 2 O 3和CaCl 2作为添加剂,在180°C下20分钟内,最佳收率增加到67.37%。另外,已经利用HPLC-MS分析来阐明反应机理。这项将“废物”转化为“财富”的研究为生物质废物的利用开辟了新途径,不仅减少了环境污染,而且具有潜在的经济价值。
