Methods for preparing alkali cellulose and water-soluble cellulose ether |
| abstract |
Provided is a method for preparing cellulose ether which is transparent as dissolved in water and has low water-insoluble content. More specifically, provided are a method for preparing alkali cellulose comprising a contact step of bringing a pulp sheet having a pore volume of 1.0 ml/g or greater, or chips into which the pulp sheet has been converted, into contact with an alkali metal hydroxide solution to obtain an alkali cellulose reaction mixture, and a drain step of draining the alkali cellulose reaction mixture; and a method for preparing water-soluble cellulose ether comprising a step of reacting the alkali cellulose with an etherifying agent. |
