THE PAPER MAKING PROPERTIES OF STRAW HOLOCELLULOSE
Canadian Journal of Research, 1948Fibrous holocellulose pulps were prepared in approximately quantitative yield from flax shives and wheat, oat, and fiber flax straw that had been macerated in a buhrstone mill and delignified by sodium chlorite. Paper hand sheets that were formed from pulps subjected to prolonged beating were glassinelike in character.

High strength holocellulose paper from bamboo as biodegradable packaging tape
Carbohydrate Polymers, 2022As the fast-growing of package business in express delivery industry, replacing traditional scotch tapes with degradable materials has attracted extensive attention. Herein, holocellulose paper (H-paper) was prepared by an efficient delignification and papermaking process from bamboo. The structure and properties of resultant holocellulose fibers and H-

Graft copolymerization of acrylonitrile on thiolated holocellulose
Acta Polymerica, 1988AbstractGraft copolymerization of acrylonitrile monomer initiated by ceric ions on bleached and thiolated holocellulosic materials was studied. The level and efficiency of grafting on the bleached holocellulose were significantly higher than on the thiolated holocellulose.

Holocellulose Determination in Biomass
2012For determination of holocellulose, the residual yield and its chemical composition during delignification by acidified sodium chlorite have been studied for bamboo (Phyllostachys heterocycla) and Sargassum (Sargassum horneri). It was then found that along with the extended number of chlorination, the residue became yellowish, and then whitish ...

Some aspects of graft copolymerization on holocellulose
Die Angewandte Makromolekulare Chemie, 1988AbstractGraft copolymers of acrylonitrile and methyl methacrylate on unmodified holocellulose and holocellulose containing between 0.3 and 4.6% thiol groups were prepared by the use of Ce4 + initiator in aqueous medium at 29°C. It was found that although the extent of graft polymer formation on the holocellulose was appreciably reduced by the presence ...

Mannose in the holocellulose of Panicum coloratum
Phytochemistry, 1981Abstract Mannose was observed in addition to other neutral sugars in the holocellulose of Panicum coloratum leaves. It was present in the hydrolyzates of extracted hemicelluloses and was particularly resistant to extraction from the α-cellulose fraction.

Mechanically strong and biodegradable holocellulose films prepared from Camellia oleifera shells
Carbohydrate Polymers, 2023Bioplastic derived from renewable lignocellulosic biomass is an attractive alternative to petroleum-based plastics. Herein, Callmellia oleifera shells (COS), a unique byproduct from tea oil industry, were delignified and converted into high-performance bio-based films via a green citric acid treatment (15 %, 100 °C and 24 h), taking advantage of their ...

Graft Copolymerization of Acrylonitrile on Bleached Holocellulose
Journal of Macromolecular Science: Part A - Chemistry, 1988Abstract The mechanism by which ceric ions interact with cellulosic materials in the presence of vinyl monomers to initiate graft copolymer formation is generally believed to involve propagation by radicals generated on the cellulosic substrate [1–5]. However, the relatively high levels of homopolymerization and low efficiencies of grafting associated ...

Graft copolymerization of methyl methacrylate on holocellulose
Journal of Applied Polymer Science, 1987AbstractGraft copolymerization of methyl methacrylate initiated by ceric ion in aqueous medium on bleached holocellulose was studied at 29°C. It was found that an increase in the concentration of ceric ion and oxidation of the holocellulose with aqueous potassium dichromate solution resulted in increased levels of incorporation of poly(methyl ...

Growth and enzyme production by Aspergillus terreus in holocellulose
Annales de l'Institut Pasteur / Microbiologie, 1984The growth of Aspergillus terreus Thom in holocellulose medium and the production of xylanase and cellulolytic enzymes were studied and compared with growth and enzyme production in xylan and cellulose powder media. Hemicellulose and cellulose were utilized simultaneously by the fungus when grown in holocellulose medium.
