Polysaccharides associated with Alpha-Cellulose

Nature, 1953
AlPHA-CELLULOSE is an insoluble fibrous residue obtained by extraction of wood, straw pulps and holocelluloses with strong alkali under carefully controlled conditions. Since the procedures used are arbitrary, the yield and composition of the alpha-cellulose prepared from any specific source may vary within rather narrow limits.

Extraction of Rice Straw Alpha Cellulose Micro/Nano Fibres

Materials Science Forum, 2017
Rice straw cellulose a biomass materials, naturally found in abundance. It is low cost, eco-friendly and biodegradable. Alpha cellulose is prepared from rice straw using chemical method namely acid hydrolysis and alkaline treatment. Both of the samples treatments were bleached using sodium chlorite (NaClO2). Alkaline treatment shows higher in producing

Effect of vegetation on alpha cellulose decomposition in littoral lake sediments

Aquatic Botany, 2010
Abstract The effect of vegetation cover on the decomposition of organic matter (alpha cellulose) was studied at three sediment depths (5, 15 and 25 cm) in the littoral area of a small Lake Kiruvere (Estonia). The experiment was carried out in two adjacent sites, with and without vegetation, using the litter bag method.

A novel method for rapid determination of alpha-cellulose content in dissolving pulps by visible spectroscopy

Cellulose, 2015
A novel method has been developed for the rapid determination of the alpha-cellulose content in dissolving pulps. After alkaline treatment of the sample, the alkaline-soluble portion of the filtrate was transformed into colloids in a medium containing ethanol (80 %). The colloid solution was then measured by visible spectroscopy.

Structure of Cotton Alpha-Cellulose

Nature, 1954
THE structure of cotton α-cellulose has been developed on the assumption that its building unit is glucose only. It is, of course, believed that raw cotton contains small amounts of pentoses which are removed by prolonged boiling in alkali and subsequent treatment of the product with 17.5 per cent sodium hydroxide during the preparation of purified α ...

A rapid and simple method to isolate pure alpha-cellulose

Phytochemical Analysis, 2000
A protocol is described to isolate small quantities of highly purified cellulose for isotopic analysis of 10–100 mg samples of secondary (Pinus sylvestris L.) and primary (Rubus idaeus L.) plant cell wall material. Elemental analysis of 350 cellulose samples isolated from pine wood samples estimated the relative carbon content to be ca.

Molecular Weight of Jute Alpha-Cellulose

Nature, 1952
MUCH work has been done on the determination of the molecular weight of cotton and wood celluloses. Staudinger and Feuerstein1 reported 1,920 as the degree of polymerization of jute cellulose (which corresponds to a molecular weight of 311,040). But Chowdhury and Bardhan2 obtained 516; their value was calculated from Staudinger's equation:
