Abstract

The process of obtaining microcrystalline cellulose from non-wood plant bast fibers (flax, hemp, kenaf) with using preliminary acid hydrolysis, alkaline sulfite-alcohol method delignification and oxidation-organosolvent processing was investigated. It is established that the conduct preliminary acid hydrolysis in the first step of obtaining microcrystalline cellulose can significantly reduce the mineral content (at 62–75 %), partly yield of pulp (at 9–12 %) and residual lignin content (at 20–30 %) compared of feedstock. Carrying out of organosolvent delignification reduces to 1 % content of residual lignin in the pulp of all studied fibers. Reduced the number of stages of the technological process of microcrystalline cellulose by combining the processes of bleaching and hydrolysis of organosolvent cellulose from plant bast fibers with using a mixture of acetic acid and hydrogen peroxide concentration of 35 and 30 %, respectively. The resulting microcrystalline cellulose from plant bast fibers meets the standard and is recommended for use in pharmaceutical companies as a filler for the manufacture of medical tablets.
