Oxygen delignified kraft pulp from eucalyptus (E. urophylla × E. grandis) was catalytically pretreated in aerobic condition using ammonium persulfate in present of catalists like cupric acetate and/or cobalt acetate in acetic acid-water solution, i. e. S2O82--Cu2+, S2O8...

Many natural polysaccharides have biological activity, which allows them to be used obtain medicines. The development of new methods for the isolation from plant materials, as well study their properties and structure, is an actual task. In this work polysaccharide galactoglucomannan (GGM) was isolated pine wood time by peroxide delignification in “acetic acid-water” medium presence (NH4)6Mo7O2...

Residues of Cistus ladanifer obtained after commercial steam distillation for essential oil production were evaluated to produce cellulose enriched solids and added-value lignin-derived compounds. The delignification extracted (CLRext) hydrothermally pretreated biomass (CLRtreat) was studied using two organosolv processes, ethanol/water mixtures (EO), alkali-catalyzed glycerol (AGO), by an alka...
