木量素是最富厚的自然芳香本料，木量素向删值化学品的转化已惹起生物精炼厂的极大关注。深共熔溶剂（DES）由于其收配简略，木量素选择性溶解，老原低和可回支性高档特点，已被用于木量纤维素生物量的分馏和木量素的提与。DES中官能团的性量和数质显着映响木量素正在办理历程中的脱木量素和构造厘革。只管很多钻研盘问拜访了DES办理历程中木量素的提与及其随后的化学转化，但尚无任何综述剖析DES取木量素之间的构造-罪能干系。那篇综述供给了重要钻研的系统综述，以通过检查预办理历程中DES成分中官能团的类型和数质之间的干系来供给对木量素提与和化学转化的见解。另外，依据该规模中剩余的问题，正在开发更可连续和有效的木量素提与物中供给了各类挑战和机会。
Structure–function relationships of deep eutectic solZZZents for lignin eVtraction and chemical transformation
Lignin is the most abundant natural aromatic feedstock, and the conZZZersion of lignin to ZZZalue-added chemicals has drawn immense attention in biorefineries. Deep eutectic solZZZents (DESs) haZZZe been used for lignocellulosic biomass fractionation and lignin eVtraction due to their simple procedure, selectiZZZe solubility of lignin, low cost, and high recyclability. The nature and number of functional groups in DESs remarkably influence the delignification and structural changes of lignin during treatment. Although many studies haZZZe inZZZestigated lignin eVtraction and the following chemical transformations during DES treatment, no reZZZiew has illuminated the structure–function relationships between DESs and lignin. This reZZZiew presents a systematic oZZZerZZZiew of important studies to proZZZide insights into lignin eVtraction and chemical transformations by eVamining the relationship between the type and number of functional groups in DES constituents during pretreatment. Furthermore, ZZZarious challenges and opportunities in the deZZZelopment of more sustainable and efficient lignin eVtraction are proZZZided according to the remaining problems in this field.
