The S/G ratio of Kraft lignin was 4.81， and a certain amount of β-O-4 linkage was retained （22.6%）. According to material balance， 37.2 g dissolving pulp， 6.2 g furfural （theoretical value 10.2 g） and 16.4 g lignin for every 100 g of eucalyptus chips.]]> 2023/9/7 16:41:14 LI Chengxiang,WU Yue,LIN Qixuan,ZHANG Chunhui,REN Junli 3true 2023/8/31 0:00:00 CHEN Zhaoxia,WANG Xin,LIANG Chen 2true 2023/8/31 0:00:00 GU Xunhong,ZHANG Tianyi,YANG Xuan,MO Wenxuan,LI Bo 1true
