Abstract
The chemical composition and reactivity of the native cellulose of cotton grass ( Eriophorum scheuchzeri ) in the production of cellulose nitroesters based on this type of raw material are investigated to assess the suitability of the native cellulose fibres of the seed pods ( Eriophorum scheuchzeri ) for the production of cellulose nitroesters on this basis. It is shown that the mass fraction of cellulose in the studied plant raw materials reaches 79 %. The degree of cellulose polymerization is 1510 units. The possibility of obtaining cellulose nitroesters in a practical yield of 64 % on the basis of this type of plant raw materials without preliminary delignifying treatment has been revealed. The chemical composition of the obtained cellulose nitroesters has been established. Their technical compliance with colloxylin H is shown. Based on the conducted studies, an intermediate conclusion is made about the potential suitability of this type of plant raw materials for the production of cellulose nitroesters.
