Abstract

Описывается способ получения производных целлюлозы, при котором целлюлозу пропитывают щелочным раствором, пропитанную целлюлозу по выбору отжимают и подвергают реакции замещения или присоединения, причем получают производное целлюлозы со степенью замещения С3. Замещенная целлюлоза является активированной аммиаком. Молярное соотношение щелочи к АГЕ (ангидроглюкозная единица) в целлюлозе к началу реакции замещения или присоединения не превышает удвоенного значения требуемой С3. Не требуется избыток щелочи, который не реагирует с целлюлозой с образованием щелочной целлюлозы, а присоединяется к целлюлозе только в качестве слабого ассоциата, для набухания целлюлозы. Расход реагентов в реакции замещения или присоединения является незначительным. Образуется меньше побочных продуктов.Международная заявка была опубликована вместе с отчетом о международном поиске.
