Abstract The effect of initial stages pulping spruce, resembling prehydrolysis and alkaline cooking was studied using CP/MAS 13 C-NMR, X-ray scattering, FSP carbohydrate composition in order to study the impact pre-treatments on fiber wall nanostructure. Removal components, hemicellulose lignin, increased porosity induced cellulose fibril aggregation. temperature pH treatment aggregate size app...

With an annual production of some 3.5 million tons between 1990 and 1995, dissolving wood pulp accounts for only 2% of the total wood pulp production. However, the high demands for cellulose purity and reactivity as well as its manifold routes of utilization are the reason for the advanced state of technology within the pulp industry. For dissolving pulp production, only acid sulfite and prehyd...

This study was carried out to investigate the extraction of cellulose acetate (CA) from cajuput (Melaleuca leucadendron) twigs and sugarcane (Saccharum officinarum) bagasse using an environmentally friendly method. At first, extracted (CT) (SB) through prehydrolysis followed by soda (NaOH) pulping elemental chlorine-free (ECF) bleaching. Later, acetylated iodine (I) as a catalyst. The obtained ...
