| titleOfInvention | Cellulose separation method |
| abstract | The present invention provides a method for separating cellulose that can be processed in a short time efficiently without using an acid or alkali to separate and recover the cellulose. A method of separating cellulose from a wood-based material mainly composed of hemicellulose, cellulose and lignin, wherein the wood-based material is charged into a dissolution tank 1 in which ethylene glycols are stored as a separating agent, and dissolved. The separating agent in the tank 1 is heated under normal pressure to a temperature within the range of 260 ° C. to 280 ° C. to react the wood-based material with the separating agent, condense the hemicellulose component evaporated from the separating agent, The pH value of the condensate is monitored as the pH value of the condensate changes from acidic to neutral as the temperature rises, and the temperature of the condensate is maintained when the change in the pH value of the condensate decreases. While dissolving lignin in the condensate, separate and recover crude cellulose suspended in the condensate. [Selected figure] Figure 1 |
