Abstract:
A method for producing a cellulose ether having a high viscosity while keeping the same degree of polymerization as that in the production of a shaped pulp without changing a raw material or production facility. More specifically, provided is a method for producing a cellulose ether including steps of: cutting or pulverizing pulp to obtain sheet-like, chip-like, or powdery cellulose pulp, wherein the pulp is formed in a form of roll whose surface layer on at least one of the circumferential side and the ends is removed, or in a form of bale whose surface layer on at least one side is removed; bringing the obtained cellulose pulp into contact with an alkali metal hydroxide solution to obtain alkali cellulose; reacting the alkali cellulose with an alkylating agent to obtain a reaction product mixture; and subjecting the reaction product mixture to purification to obtain the cellulose ether.

Claim (Index 3):
The method for producing a cellulose ether according to  claim 1 , wherein the bale is a hexahedron with quadrangle upper and lower bottom surfaces, and the surface layer of the bale is removed in a depth of 1.25 to 12.5% of a height, a length, or a depth of the bale.
