摘要:The present invention relates to a process for selectively producing a celluloseether derivative with a very high reaction efficiency of an organohalide compound. Thereis provided a process for producing a cellulose ether derivative such as carboxymethylcellulose and hydroxyethyl cellulose in which a low-crystalline powdery cellulose having acrystallinity of 50% or less is reacted with an organohalide compound such as ethylenechlorohydrin, a monohaloacetic acid and a salt of the monohaloacetic acid in the presenceof a base.
