FIELD: chemistry.
SUBSTANCE: method of obtaining monocrystalline cellulose includes cellulose destruction, washing the product with water and bases, drying. A cellulose-containing material is processed with solutions of heteropolyacids in water, solutions of heteropolyacids in lower aliphatic carboxylic acids or in water mixtures of carboxylic acids with any ratios water-carboxylic acid without an addition of mineral acids at a temperature of 100-120°C for 15-120 minutes with the concentration of heteropolyacids of 0.1-15 mol.%.
EFFECT: invention makes it possible to simplify and reduce the process duration, increase efficiency, manufacturability and ecological compatibility of the MCC manufacturing.
