FIELD: chemistry.
SUBSTANCE: invention relates to chemical engineering. Wood is treated with an acylating mixture, which contains carboxylic acid, thionyl chloride and trifluoroacetic acid. The desired product is extracted using a polar solvent with subsequent drying. The carboxylic acid used has general formula RCHOHCOOH, where R is hydrogen or -CH3 in amount of 0.02 to 0.04 moles per 1 g of wood.
EFFECT: invention widens the range of cellulose esters and reduces pollution of the environment.
