| titleOfInvention | Method for preparing microcrystalline cellulose from waste cotton |
| abstract | The invention relates to a method for preparing microcrystalline cellulose from waste cotton. The method comprises the following steps of: (1) mixing and contacting the waste cotton with an acid solution to obtain acidified waste cotton; and (2) carrying out contact reaction on the acidified waste cotton and an oxidant at the condition of pH (Potential of Hydrogen) of 2 to 7 in the presence of water. According to the method provided by the invention, the waste cotton can be hydrolyzed and bleached at the same time in one step to obtain the microcrystalline cellulose, and the processes of bleaching and hydrolyzing do not need to be independently carried out, so that the production process of the microcrystalline cellulose can be simplified; and the method is free of high-temperature alkali cooking and degreasing processes, so that the material consumption and the energy consumption in the whole preparation process can be greatly reduced. |
