摘要： Disclosed are a method of preparing acetylated cellulose ether, and acetylated cellulose ether prepared thereby. Here, the disclosed method of preparing the acetylated cellulose ether includes dissolving acetylated cellulose ether in an organic solvent to obtain a mixture comprising a solution of the acetylated cellulose ether; removing an insoluble component that is insoluble in the organic solvent from the mixture; and adding the mixture to water to precipitate the acetylated cellulose ether. The acetylated cellulose ether prepared thereby has a turbidity of less than 40 formazin turbidity units (FTU).

摘要： There is disclosed a process for the derivatization of cellulose comprising the sequential steps: a) mixing cellulose with a viscosity below 900 ml/g with an aqueous solution to obtain a liquid, wherein particles comprising cellulose in said liquid have a diameter of maximum 200 nm, wherein the temperature of the aqueous solution is below 20° C., and wherein the pH of the aqueous solution is above 12, b) subjecting the liquid to at least one of the steps: i) decreasing the pH of the liquid with at least 1 pH unit, ii) increasing the temperature by at least 20° C., and c) derivatization of the cellulose. Advantages include that there is provided the possibility to derivatize cellulose faster and to a greater extent after the treatment. Further the yield is improved. The product quality is improved and the manufacture is cheaper and easier.
