摘要： An object is to provide a cellulose acetate remarkably good in hue even when a low-quality pulp is used.
A method for producing the cellulose acetate includes a step (1) of crushing a wood pulp, a step (2) of bringing the crushed wood pulp into contact with acetic acid to subject the pulp to pretreat the wood pulp, a step (3) of causing the wood pulp to react with acetic anhydride after the pretreatment to acetylate the pulp, a step (4) of hydrolyzing the cellulose acetate, which is yielded by the acetylation, and a step (5) of precipitating the cellulose acetate, an acetylation degree of which is adjusted by the hydrolysis. In the hydrolyzing step (4), in a hydrolysis reaction system, a concentration of oxygen is set to 3% or less.

摘要： A film of 15 to 45 μm thick containing a cellulose acylate and an aromatic ester oligomer having a repeating unit derived from a dicarboxylic acid and a repeating unit derived from a diol, in which the repeating unit derived from a dicarboxylic acid has a ratio m/n of from 0/10 to 3/7, m and n represent a molar proportion of a repeating unit derived from an aliphatic dicarboxylic acid and an aromatic dicarboxylic acid, respectively, and the film satisfies |Rth(590)|≤50 nm; has a good appearance and is free of deterioration in display performance when the film with a thin thickness is produced in the form of a roll, achieves a high pencil hardness by imparting a high Knoop hardness to the film, even with a hard coat layer provided, and is free of display unevenness on installing the film in a liquid crystal display device.

摘要： A method is used to prepare silver nanoparticles in the form of a silver nanoparticle cellulosic polymeric composite. A cellulosic polymer, organic solvent having a boiling point at atmospheric pressure of 100° C. to 500° C. and a Hansen parameter (δTPolymer) equal to or greater than that of the cellulosic polymer, and a nitrogenous base are mixed to form a premix solution. Upon heating the premix solution to a temperature of at least 75° C., a solution of reducible silver ions is added that is equimolar or less in relation to the nitrogenous base. The weight ratio of reducible silver ions to the cellulosic polymer is 5:1 to 50:1. The resulting silver nanoparticle composite is cooled, isolated, and re-dispersed in an organic solvent, providing a non-aqueous silver-containing dispersion comprising the silver nanoparticle cellulosic polymeric composite.

摘要： The invention relates to the separation of manure in fractions and the treatment of said fractions in order to retrieve useful components to produce manure-derived bioplastic and other manure-derived bioproducts. The invention further relates to a method for producing composite (bio)plastic, and to a method for producing fibre from regenerated manure-derived cellulose. The methods include the steps of: flocculation treatment and a filtration treatment; pulping the manure-derived solid fractions; acetylation of the manure-derived dissolving-grade cellulose pulp with acetic anhydride and a catalyst; extracting fermentable components from the different fractions of the manure to produce monocarboxylic acids for use in the monocarboxylic acid carrier solution. Furthermore methods are disclosed for forming composite bioplastics with resin binding agents; and for spinning yarn from cellulose pulp.
