Abstract
A SERIES of anion-exchange derivatives of cellulose has been prepared and characterized. The preparative technique was based on the reaction of alkali cellulose with organic halides and sulphates; this is a well known method for preparing cellulose ethers1, and by choice of suitable reagents produces ion exchangers. A reaction of this type can be represented by equations (1) and (2): 
The chloro compound is the most frequently used halide, n being generally 1 or 2, and R and R′ being hydrogen or alkyl, aryl, etc., radicals.
