To develop novel biorefinery concepts, the use of bio‐based catalysts and solvents must be aligned with the principles of green chemistry. In this context, biogenic 2,5‐furandicarboxylic acid (FDCA) is a very promising yet underused molecule with high potential for application as an acid catalyst, combining feasibility and sustainability with efficient and straightforward recovery. In this study, FDCA was evaluated as a catalyst in the recently developed OrganoCat pretreatment, a biphasic lignocellulose fractionation system. The catalyst was investigated for the efficient fractionation of the three main components—lignin, cellulose and noncellulosic sugars—with particular focus on the lignin quality, on the effect on enzymatic hydrolysis of the cellulosic residue, and on the noncellulosic sugar extraction. To address recovery of FDCA from the OrganoCat system, a method was developed, leading to the recovery of >97 % of FDCA with a spectroscopic purity of >99 %, maintaining full activity in consecutive runs.

2,5-呋喃二甲酸作为生物源和可回收催化剂的一步一步木质纤维素分级分离

要开发新的生物精炼概念，必须将生物基催化剂和溶剂的使用与绿色化学原理相结合。在这种情况下，生物型2,5-呋喃二甲酸（FDCA）是一种非常有前途但尚未充分利用的分子，具有用作酸催化剂的巨大潜力，将可行性和可持续性与有效而直接的回收相结合。在这项研究中，FDCA被评估为最近开发的OrganoCat预处理（一种双相木质纤维素分馏系统）中的催化剂。对催化剂进行了有效分离的三种主要成分（木质素，纤维素和非纤维素糖）的研究，特别关注木质素的质量，对纤维素残留物的酶促水解的影响以及对非纤维素糖的提取。
