摘要
生物可降解的胆碱醋酸离子液体在玉米秸秆预处理过程中显示出高效的去木质素能力。通过该简单、无毒、绿色的工艺,可从离子液体-玉米秸秆溶液中,直接得到含综纤维素98.0%的富纤维产品,并且木质素含量从13.7%下降到2.0%。
Biodegradable ionic liquid(IL) choline acetate shows highly efficient delignification ability in cornstalk pretreatment process. Cellulose-rich products with 98% holocellulose and 2% lignin decreased from original 13% could be directly obtained from the IL-cornstalk solution by the simple, non-toxic, and green process.
