Abstract: | The synthesis of new 6‐deoxy‐6‐trialkylammonium cellulose derivatives obtained by nucleophilic displacement reactions of p‐toluenesulfonyl celluloses with various amines is described. Water soluble cellulosics could be prepared using a N,N‐dimethylformamide/water mixture as the reaction medium. Detailed studies concerning the influence of reaction time and temperature as well as the water content on the solubility of the products were carried out. Even the synthesis of large sample amounts was possible using optimized reaction conditions. The 6‐deoxy‐6‐trialkylammonium cellulose derivatives are water‐soluble even at low degrees of substitution, i. e., in the range of 0.2 and 0.5. The structure was confirmed by means of 1H and 13C NMR spectroscopies. |
