Lignin is a renewable and abundant aromatic polymer found in plants. We herein propose a “cutting tail” methodology to produce phenol from lignin, which is achieved by combining Ru/CeO2 catalyst and CuCl2 oxidant via an oxidation–hydrogenation route. Phenol was obtained from separated poplar lignin with 13 wt % yield. Even raw biomass, such as poplar, birch, pine, peanut, bamboo willow, and straw, could be converted into phenol in 1–33 mg per gram of biomass.

木质素通过氧化加氢策略脱烷基为苯酚

木质素是植物中发现的一种可再生且丰富的芳香族聚合物。我们在本文中提出了一种从木质素生产苯酚的“削减尾巴”方法,该方法是通过氧化/氢化途径将Ru / CeO 2催化剂和CuCl 2氧化剂结合起来实现的。从分离的杨木木质素中以13wt%的产率获得苯酚。甚至原始生物质(例如,杨木,桦木,松树,花生,竹柳和稻草)也可以以每克生物质1–33 mg的量转化为苯酚。
