The present invention provides for a method of fermenting or saccharifying a biomass comprising: (a) (i) contacting a biomass comprising a polysaccharide, and an ionic liquid (IL) to form a first solution, or (ii) providing the first solution comprising the biomass and the IL, (b) contacting the first solution and carbon dioxide such that the first solution results in a lower pH, (c) introducing (i) an enzyme capable of enzymatically to breakdown at least one bond in the polysaccharide or a breakdown product of the polysaccharide, and/or (ii) a microorganism that capable of producing the enzyme and/or fermenting the polysaccharide or a breakdown product of the polysaccharide, such that the polysaccharide is at least partially broken down and the first solution is transformed into a second solution.

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.

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.

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.

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 present invention provides a cellulose fiber manufacturing method including the following steps: a solution preparation step for dissolving cellulose in a mixed solvent of an aprotic polar solvent and a quaternary onium salt; a discharge step for discharging the obtained solution in a fibrous form through a spinneret, the moisture content of the solution at the time of discharging falling within the range from 0.05 mass % to 8 mass %; and a solidification step for solidifying the discharged fibers in a water-based solidification bath containing water and the mixed solvent.

A process for the manufacture of butanol, acetone and other renewable chemicals utilizes one or more of by-products of the manufacture of malt whisky, such as pot ale and spent lees, biomass substrates, such as paper, sludge from paper manufacture and spent grains from distillers and brewers, and diluents, such as water and spent liquid from other fermentations. 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.

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.
