This article examines the structure of oilseed flax straw. As part of the study, the chemical composition of oilseed flax straw have been examined.
The results of the study indicate the possibility of obtaining cellulose directly from oilseed flax straw. The optimal reaction mixtures and conditions for the process of obtaining cellulose from wastes of primary f flax straw processing have been selected. The results of the study showed that generally thick stems are characterized by a lower cellulose content compare to the thin, uniform straw. In addition, the straws have an increased mass fraction of acid-insoluble lignin, which provides special strength and creates difficulties for grinding. The chemical composition and physicochemical properties of cellulose were also investigated. The analysis results indicate the possibility of processing this type of raw material
in order to obtain cellulose suitable for further chemical modifications.
Key words: flax, processing, straw, bonfire, cellulose.
