摘要
利用对甲苯磺酸/氯化胆碱(TA/CC)制备的低共熔溶剂(DES)处理碱木质素,提取得到富含酚类的木质素精油,将其添加到杨木浆中,制备了抗菌纸。结果表明,DES处理后得到的木质素精油中含有大量酚羟基,制得的抗菌纸对大肠杆菌的抗菌率约100%,在食品包装用纸、医疗用纸等领域具有较大的应用潜力。
Deep eutectic solvent(DES)-pretreated alkaline lignin was prepared using p-toluenesulfonic acid and choline chloride(TA/CC)and resulted in a phenol-rich lignin essential oil extract.It was subsequently incorporated into poplar pulp to produce antibacterial paper.The results demonstrated that the pretreatment of lignin with DES led to the generation of a significant number of phenolic hydroxyl groups,and the prepared antibacterial paper exhibited an inhibition rate of approximately 100%against Escherichia coli,suggesting significant potential applications in fields such as food packaging paper and medical paper.
