Abstract In this study, we evaluated zirconium oxychloride (ZrOCl2), an eco-friendly Lewis acid as a catalyst for conversion of glucosamine (a monomer of chitosan obtained from shell-crustacean food waste) into levulinic acid (LA). In a ZrOCl2-catalyzed hydrothermal reaction, 21.29 mol% of LA was obtained using optimized conditions with 50 g/L glucosamine and 15 mol% ZrOCl2, at 200 °C for 20 min. Our results demonstrate the potential of glucosamine as a recyclable feedstock and ZrOCl2 as an eco-friendly catalyst for platform chemical synthesis.

使用氯氧化锆从氨基葡萄糖生产乙酰丙酸

摘要 在这项研究中,我们评估了氯氧化锆 (ZrOCl2),一种环保的路易斯酸,作为将葡萄糖胺(一种从壳甲类食物垃圾中提取的壳聚糖单体)转化为乙酰丙酸 (LA) 的催化剂。在 ZrOCl2 催化的水热反应中,使用 50 g/L 葡萄糖胺和 15 mol% ZrOCl2 的优化条件,在 200 °C 下反应 20 分钟,获得了 21.29 mol% 的 LA。我们的结果证明了氨基葡萄糖作为可回收原料和 ZrOCl2 作为平台化学合成的环保催化剂的潜力。
