Quaternary ammonium cellulose anion preparation

Recently, we have characterized tertiary amine and quaternary ammonium celluloses made either aqueously or non-aqueously by a variety of instrumental techniques. These techniques have also been used to follow effects of a given anion on the cellulose matrix of a quaternary ammonium cellulose exchanger when the exchanger prepared non-aqueously comes in contact with water. 

Use of non-aqueous solvents such as methanol for the preparation of the sodium cel 1 u1 osates, tertiary butanol for the preparation of the tertiary amine, diethyl ami noethylcellulose and absolute ethanol for the preparation of quaternary ammonium compounds from the tertiary amine celluloses has made it possible to form cellulose anion exchangers in fabric form that contain up to 4.0% nitrogen. Usually, the maximum amount of nitrogen obtained with aqueous preparations is approximately 0.7%.
