As noted in Fig. S1, the unmodified lignin was soluble in THF and dispersible in the rest of the solvents, thus exhibiting an affinity to both polar and nonpolar media. On the contrary, the modified lignin sample was soluble in toluene, dispersible in the THF, but insoluble in solvents ...
Article The Relationship of Acid Insoluble Lignin and Acid Soluble Lignin to the Lignins of the Middle Lamella and Cell Wall in Eucalyptus regnans was published on January 1, 1975 in the journal Holzforschung (volume 29, issue 4).
Tembec and Georgia Pacific are operating sulphite pulp mills in North America, which utilise a dilute acidhydrolysis processto dissolve hemicellulose and lignin from wood, and produce speciality cellulose pulp. Thehexosesugars in the spent sulphite liquor are fermented to ethanol. The lignin is either...
3) acid-soluble lignin 酸溶木质素 1. The holocellulose, α-cellulose, lignin, acid-soluble lignin, and the ratio of cellulose to lignin were investigated. 主要研究内容为综纤维素、α 纤维素、半纤维素、木质素、酸溶木质素的含量及综纤维素与木质素的比值变化等。
