The effect of the composition of nitrification media on the nitrogen content of cellulose nitrate prepared from treated cotton fluff in Iraq

Abstract

Effect of nitrating agent on the degree of nitration of cellulose as a nitrogen
content for cellulose nitrate has been studied . Cellulose nitrate prepared by reacting
triple nitrating a gent (( conc, HNO3 , fuming H2SO4 and H2O )) with (α -cellulose )
which prepared previously from bleached linter cotton, that had been treated
mechanically and chemically in Iraq .
This research demonstrated that the nitrogen content for cellulose nitrate
increase with increasing HNO3 and with decreasing H2O in nitrating agent , also
fuming H2SO4 has a main rule as a dehydrant through the reaction .
Also research stated that all ranges of industrial cellulose nitrate can be prepared
by using nitrating agent containing HNO3 in the range of (( 21.8% - 25.24% by wt )) .
