Description
Предмет изобретени Subject invention
Способ получени простого водорастворимого эфира целлюлозы, содержащего группы триметилоксипропиламмони , путем обработки производных целлюлозы хлористым глицидилтриалкиламмоиием , отличающийс A process for the preparation of a water-soluble cellulose ether containing trimethyloxypropylammonium groups by treating cellulose derivatives with glycidyltrialkylmmonium chloride, characterized by
тем, что, с целью упрощени процесса и получени эфира целлюлозы с высокой степенью замещени , обработке подвергают 2- 4%-ный раствор целлюлозы в 32-34%-ном водном растворе гидроокиси бензилтриэтиламмони при 5-40°С.By the fact that, in order to simplify the process and obtain cellulose ether with a high degree of substitution, a 2-4% solution of cellulose in a 32-34% aqueous solution of benzyltriethylammonium hydroxide at 5-40 ° C is subjected to processing.
