An object of the present invention is to provide cellulose acetate that has excellent compatibility with a resin, can reinforce a resin, and has excellent thermal stability. An embodiment of the present invention is cellulose acetate having a cellulose triacetate I crystal structure, wherein a temperature at which a weight loss relative to weight at 100° C. reaches 5% is 200° C. or higher when the cellulose acetate is heated at a heating rate of 10° C./min under a nitrogen atmosphere.
METHOD FOR SEPARATING CELLULOSE
In a method, a cellulose component is separated from plant materials consisting of cellulose, hemicellulose and lignin as principal components. The method includes the step of: rinsing the plant materials into a separating agent comprising ethylene glycols, heating the separating agent with the plant materials up to a high temperature less than the boiling point of the separating agent and reacting the separating agent with the plant materials, evaporating the hemicellulose from the separating agent reacted with the plant materials while dissolving the lignin of the plant materials into the separating agent, finally collecting the remaining cellulose component of the plant materials floating on the surface of the separating agent.
Production of an amine oxide by oxidation of a tertiary amine
A method for producing an amine oxide by oxidation of a tertiary amine in a reactor under continuous introduction of tertiary amine in a reaction fluid and export of amine oxide, wherein a suitable surface-to-volume ratio and/or a suitable flow speed with corresponding surface/volume loads are selected in the continuous process. The reaction fluid is usually reacted in the reactor with a laminar flow.
Cellulose Fiber Manufacturing Method
Provided are: a cellulose fiber manufacturing method for suppressing the occurrence of thread breakage in a spinning step and unevenness in the physical properties of obtained fibers, thus enabling stable spinning; and cellulose fibers that are highly strengthened, in which fibrillation is suppressed, and that have a pleasant texture.

The process includes treating a substrate to hydrolyze it and fermenting the treated. Also provided is a biofuel including butanol manufactured according to the process.
METHOD FOR PREPARING CELLULOSE DOPE
The invention relates to a method for preparing a cellulose dope comprising mixing and dissolving the cellulosic raw material in dilute and concentrated aqueous organic solvent in a two-stage process to form a homogeneous slurry, followed by heating the homogeneous slurry to obtain a cellulose dope containing 11% to 20% cellulose by weight. The invention also relates to a cellulose dope comprising 11% to 20% cellulose by weight and 73% to 79% aqueous organic solvent wherein the concentration of the cellulosic and metallic impurities in the cellulose dope shows a percent reduction of 20% to 50% from the cellulosic raw material.
CELLULOSE-CONTAINING MATERIALS
Disclosed is a process for solubilising cellulose and coagulating the resulting solution to form a cellulose-containing material. The process comprises contacting a cellulose source with a solvent comprising zinc ions and formic acid to provide a solution, coagulating the solution to provide a solid material, treating the solid material, and isolating the solid material after treatment, to provide the cellulose-containing material. The process can further comprise solubilising protein and coagulating the resulting solution to form a cellulose/protein-containing material. The cellulose-containing materials and cellulose/protein-containing materials can be produced, for example, as reconstituted fibres and films.
CELLULOSE NANOCRYSTAL SEMICONDUCTOR MATERIAL AND MANUFACTURING METHOD THEREOF
The present disclosure relates to a semiconductor material including a cellulose nanocrystal and a manufacturing method thereof. Particularly, according to the present disclosure, by attaching an electron withdrawing group or an electron donating group to the surface of the cellulose nanocrystal which is a nonconductor, holes or free electrons are formed in the cellulose nanocrystal, and the cellulose nanocrystal may be used as a semiconductor material.
CELLULOSE NANOCRYSTAL-BASED EMULSIONS AND USES THEREOF
This invention relates generally to cellulose nanocrystal-based emulsions that can serve as a spray adjuvant for improved agrochemical application efficiency. More particularly, the cellulose nanocrystal-based emulsions are nanocellulose-stabilized Pickering emulsions having a semi-liquid formulation of colloidal cellulose nanocrystals and biopolymers that can substitute currently used surfactants and drift reducing agents in agrochemicals. The cellulose nanocrystal-based emulsions are suitable with both water soluble and oil soluble active ingredient chemistries, and the shear characteristics of the emulsions make them suitable for oil in water-based spray applications. Droplet size distribution can be tuned by changing the ingredient concentrations, thus helping control particle drift. Moreover, a stable cross-linked network formation facilitates the entrapment and encapsulation of volatile agrochemical chemistries, thus preventing their volatilization and reducing vapor drift.
Process for the extraction of metal pollutants from treated cellulosic biomass
The present invention relates to a process for extracting oxidised metal pollutants from treated cellulosic or lignocellulosic biomass to recover the metal. The treatment also generates a cellulosic or lignocellulosic biomass which can to be used as a feedstock for biofuel, for making cellulose containing materials, and provides a source of other renewable chemicals.
