Abstract

Eucalyptus wood was micronized chemically with glycol ether in the presence of an acid catalyst. The chemical properties of the lignin recovered from the micronized wood were investigated to understand the behavior of wood components during the chemical micronization process. When the eucalyptus wood meals were micronized in the presence of a 3% acid catalyst, the lignocellulosic microfines comprised 47.5% of the wood meals and its Klason lignin content was 3.3%. Most of the lignin was eluted using alcohol, acetone, and 0.5 N NaOH. Moreover, lignocellulosic microfines were obtained as a result of the use of glycol ether and the acid catalyst for eluting lignin. The lignocellulosic microfines obtained through the glycol ether organosolv process mainly comprise glucose-dominant monosaccharides. therefore, these lignocellulosic microfines have a high potential for application as dissolving cellulose and/or cellulose nanocrystals.
