Solvent Delignification of Kenaf and Sugar Sorghumstems

The chemical composition of stalks of kenaf and sugar sorghum was studied. Established that the kenaf and sugar sorghumstalks contain more cellulose, pentosans, minerals and less lignin than wood. The influence of main technological parameters on the quality indexes of organosolvent pulp obtained from kenaf and sugar sorghum stems was investigated. The possibility of bleaching organosolvent pulp obtained from stems of kenaf using hydrogen peroxide without chlorinecompounds to 80 % whiteness was experimentally proved.
