تأثير تركيب وسيط النترنة على المحتوى النتروجيني لنترات السليلوز المحضرة من زغب القطن المعالج في العراق

الملخص EN

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 )) .
