Catalytic synthesis of 2‐furyl methanol from leaves of <i>Acacia auriculiformis</i> using zinc chloride: a pathway to green chemical synthesis

Abstract BACKGROUND The catalytic conversion of biomass‐derived feedstocks into valuable chemicals is a key focus in sustainable chemistry. This study explores the zinc chloride ( ZnCl 2 )‐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% ZnCl 2 catalyst. The reaction pathway involves ZnCl 2 ‐assisted thermal hydrolysis, dehydration, and mild hydrogenation of hemicellulose‐derived pentose sugars. Comparative catalyst studies (using BaCl 2 , NaOH , ZnO , CaO , and MgO ) revealed that ZnCl 2 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 ZnCl 2 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).
