More specifically, cellulose is insoluble in water majorly because of quite robust intermolecular and intramolecular hydrogen bonding between the discrete cellulose fibrils. Chemical modifications of hydroxyl groups of cellulose have been shown to greatly improve solubility and therefore seen as an option ...
After obtaining a raw material solution (S) by dissolving a cellulose feedstock in an ionic liquid comprising an imidazolium compound, the raw material solution (S) is extruded in a coagulation liquid (6) in which the imidazolium compound is soluble and the cellulose is insoluble, causing the ...
In this work, pecan (Carya illinoinensis) nutshell (NS) fiber and its structural components, holocellulose (HC) and acid insoluble lignin (AIL), were ... S Agustin-Salazar,P Cerruti,LN Medina-Juárez,... - 《International Journal of Biological Macromolecules》 被引量: 0发表: 2018年 Thermal...
Cellulose acetate is an ester in which cellulose (cotton linters or wood pulp) is treated with a mixture of acetic anhydride, acetic acid and concentrated sulphuric acid. This solution, when treated with water, forms a flocculent white mass of cellulose acetate which is used as a fiber and ...
capable of improving strength, heat resistant, rigidity, or the like of molded products produced by molding a thermoplastic resin added with the above filler, by heat-treating water-insoluble cellulose-based filler in the presence of a specific quantity of an alkyl phosphate-type surfactant (or it...
Cellulose waste biomass is the most abundant and attractive substrate for "biorefinery strategies" that are aimed to produce high-value products (e.g. solvents, fuels, building blocks) by economically and environmentally sustainable fermentation processes. However, cellulose is highly recalcitrant to biod...
is known that the absolute intensity of the1H NMR spectrum of hydrochar in D2O is lower for the functional groups compared with that in H2O. We could assume a limit case, where the absolute intensity of peak 4 did not change from H2O to D2O. Taking peak 4 as an internal standard, it ...
Water-insoluble HBS lignin was separated from the liquor reaction mixture by water precipitation. Recovery high boiling solvents (RHBS) is able to recycle as a pulping solvent indicating that the HBS method is a pulping process of bamboo with saving energy, saving resources and non-pollution. ...
In contrast, the cellulose fibers digested by secreting cells appear to be evenly ablated from the outer layer of microfibers, which is consistent with a previous report14. Taken together, these results indicated that the cellulase-displaying strain employs a "tearing" mechanism distinct from the...
is designed for use in water dispersions, being insoluble in water but dispersing in water to form colloidal sols below 1% and white opaque gels above the 1% usage level. It is used as a heat shock stabilizer and bodying agent in frozen desserts, as an opacifier in low-fat dressings, as...
