Abstract
Разработан «зеленый» метод получения из древесины ели целлюлозного продукта с высоким содержанием альфа-целлюлозы, включающий стадию делигнификации древесины пероксидом водорода в среде «уксусная кислота – вода – сернокислотный катализатор» и стадию щелочной обработки NaOH. Осуществлен подбор условий получения, обеспечивающих приемлемый выход (30–31% масс.) целлюлозного продукта, содержащего 97,3–98,0% масс. альфа-целлюлозы.

The «green» method of obtaining from fir-wood the cellulosic product with high content of alpha-cellulose was developed. It consists of the stage of wood delignification by hydrogen peroxide in the medium «acetic acid – water – sulfuric acid catalyst» and of the stage of alkaline treatment by NaOH
Preparation conditions were selected which allow to obtain with an acceptable yield (30–31% mas.) the cellulosic product containing 97,3–98,0% mas. of alpha-cellulose
