Pyrolysis of cellulose under vacuum and atmospheric pressure gave a tar containing various amounts of 1,6-anhydro-β-D-glucopyranose, 1,6-anhydro-β-D-glucofuranose, α- and β-D-glucose, 3-deoxy-D-erythro-hexosulose, oligo- and polysaccharides, and some dehydration products.

Cellulose: Chemistry of Cellulose Derivatization
2012This chapter gives an overview on various possibilities of cellulose functionalization. Particular attention was paid on homogeneous-phase conversions of cellulose in reaction media based on both aprotic-dipolar solvents in combination with salts and ionic liquids. Paths for cellulose esterification via in situ activated carboxylic acids are discussed.

Abstract Cellulose is one of the major commercial products of Sweden and constitutes the most abundant of the natural polymer systems. Thus, it is of interest to review the molecular design and architecture of cellulose with particular reference to the controls of its biosynthesis.

Publisher Summary Cellulose is a high polymer of β-1,4-linked D-glucose residues. All methods for the isolation, purification, and solubilization of cellulose seem to depolymerize the molecule more or less. However, by improved methods giving a minimum of depolymerization, higher values for the degree of polymerization (DP) are obtained.

Electrospinning Cellulose and Cellulose Derivatives
Polymer Reviews, 2008Many solvents suitable for wet or dry spinning of cellulose and cellulose derivatives have also been investigated as solvents for electrospinning. Solvents for cellulose are not completely volatile and have required coagulation steps to ensure complete removal of the solvent from electrospun fibers and produce stable fibers.

The Characterizations of Bacterial Cellulose and Dialdehyde Celluloses from Bacterial Cellulose
Key Engineering Materials, 2007The characteristics and properties of bacterial cellulose and dialdehyde celluloses from bacterial cellulose were studied by XRD, TG-IR and adsorption capacity testing. The crystal cell parameters of BC were calculated and approximated to that of monocline crystal cell model. The XRD profiles showed that the crystallinity degree of BC was 66%, and that

Multilayers of cellulose derivatives and chitosan on nanofibrillated cellulose
Carbohydrate Polymers, 2014The aim of this work was to study the effect of solution conditions and polysaccharide structure on their Layer-by-Layer (LbL) deposition on nanofibrillated cellulose (NFC). Multilayer build-up of cellulose derivatives and chitosan on NFC model surfaces was studied using Quartz Crystal Microbalance with Dissipation (QCM-D) and Colloidal Probe ...
