FIELD: chemistry.SUBSTANCE: invention relates to production of powdered cellulose from cellulose materials. The method involves breaking down cellulose material using a Lewis acid solution and an organic solvent while stirring. The breakdown process takes place at low concentration of the Lewis acid solution using a minimal amount of organic solvent. The product is washed and dried. The cellulose material used is different types of lignocellulose materials obtained from semi-finished wood products which are obtained during processing thereof at paper mills, straw of grain crops and waste paper material.EFFECT: obtained powdered cellulose has high chemical reactivity and can be used in analytical chemistry, cosmetic and pharmaceutical industry, to modify cellulose and lignocellulose materials and when producing derivatives thereof for special purposes.2 tbl, 4 ex |
