摘要

生物质原料催化转化为有价值的化学品是可持续化学的一个关键焦点。以金合欢叶为原料,研究了氯化锌催化合成2-呋喃甲醇的工艺。系统考察了催化剂浓度、反应温度、反应时间等参数对产物收率的影响。结果气相色谱-质谱分析结果证实,在40℃、1.0% ZnCl2催化剂条件下,2-呋喃甲醇的最大产率为9.35%,相当于458.04 mg g−1的进料。反应途径包括zncl2辅助的半纤维素衍生戊糖的热水解、脱水和轻度氢化。对比催化剂研究(使用BaCl2、NaOH、ZnO、CaO和MgO)表明,ZnCl2在转化过程中具有优越的选择性和效率。结论氯化锌是木质纤维素选择性合成2-呋喃甲醇的有效催化剂。这项研究强调了ZnCl2在生物质增值方面的潜力,为生物基化学生产提供了一条绿色和可持续的途径,并为未来的工业应用提供了有价值的见解。©2025化学工业学会(SCI)。

Catalytic synthesis of 2-furyl methanol from leaves of Acacia auriculiformis using zinc chloride: a pathway to green chemical synthesis

Catalytic synthesis of 2-furyl methanol from leaves of Acacia auriculiformis using zinc chloride: a pathway to green chemical synthesis

BACKGROUND

The catalytic conversion of biomass-derived feedstocks into valuable chemicals is a key focus in sustainable chemistry. This study explores the zinc chloride (ZnCl2)-catalyzed synthesis of 2-furyl methanol from Acacia auriculiformis leaves. The influence of reaction parameters, including catalyst concentration, temperature, and time, on product yield was systematically investigated.

RESULTS

Gas chromatographic–mass spectrometric results confirmed the formation of 2-furyl methanol, with a maximum yield of 9.35%, equivalent to 458.04 mg g−1 of feed, obtained at 40 °C using 1.0% ZnCl2 catalyst. The reaction pathway involves ZnCl2-assisted thermal hydrolysis, dehydration, and mild hydrogenation of hemicellulose-derived pentose sugars. Comparative catalyst studies (using BaCl2, NaOH, ZnO, CaO, and MgO) revealed that ZnCl2 exhibited superior selectivity and efficiency in the conversion process.

CONCLUSION

Zinc chloride proved to be an effective catalyst for the selective synthesis of 2-furyl methanol from lignocellulosic biomass. This study highlights the potential of ZnCl2 for biomass valorization, offering a green and sustainable route to bio-based chemical production and contributing valuable insights for future industrial applications. © 2025 Society of Chemical Industry (SCI).
