Antioxidant activity of lignin phenolic compounds extracted from kraft and sulphite black liquors.
The antioxidant activity of the phenolic compounds present in industrial black liquors obtained from the two cooking processes (kraft and sulphite) used in Portugal to produce Eucalyptus globulus pulp was evaluated. The black liquors treated at several pH values were extracted with ethyl acetate. Phenolic fractions were further separated by liquid chromatography of the crude extracts of kraft l...
متن کاملModification of Spruce Sulphite Pulp by Cellulase Treatment
Enzymatic treatment of different sulphite pulps with cellulases has been studied in this work. Endoglucanases were shown to beneficially alter the properties of both paper-grade and dissolving-grade pulps. In the case of the paper-grade pulp, the treatment with endoglucanase resulted in a considerable reduction of the pulp refining time without decrease in strength properties. While for the dis...
متن کاملThe Alcoholic Liquors of India
an error founded on insufficient knowledge can be easily made clear. Passages in the Mahabharata (an epic poetn dealing with events 1200 B.C., but put together about 1,000 years later), I etc., show that drunkenness was common in ancient India; and this may be gathered also from the old Hindu law books, which forbid the use of wine (e.g. Mandva-Dhdrma-Sdstra, xi., 1-46 ff). In the Abhila-Shithd...
متن کاملDeresination Options in Sulphite Pulping
Three methods for improved deresination of sulphite pulps were evaluated, namely, alkaline washing, enzyme treatment, and pulp fractionation. Alkaline washing appears to come at a high cost, because caustic is expensive and affects cellulose chain length, as indicated by lower viscosity of the pulps. Thus this is not a viable option for pulps that are sensitive to changes in viscosity. Enzyme t...
