Process for preparing cellulose ethers with cyclic ethers as suspending agents

A process for preparing cellulose ethers from cellulose and alkylating agents, in the presence of a base and water and a water miscible cyclic ether as a suspending agent consisting essentially of dioxane and/or THF comprising the stages:

• a) alkalization,
• b) subsequent alkylation, and optionally stage
• c) hydroxyalkylation which would be performed between stages a) and b);
• wherein the water-miscible cyclic ether is admixed in
• 1) stage a) or,
• 2) if optional stage c) is performed then in stage a) or stage c) , and wherein after stage a) and before stage b) a part of the water-miscible cyclic ether together with a part of the .water are removed by distillation.
