ALKYLENE OXIDE MODIFIED HARDWOOD CELLULOSE

Disclosed is a process for producing reactive cellulose for use in the manufacture of cellulose acetate having superior clarity by mercerizing hardwood cellulosic material and reacting it with an hydroxyalkylating agent to a degree of molar substitution ranging from 0.04 to 0.15 per anhydroglucose u...

Beschreibung
Zusammenfassung:	Disclosed is a process for producing reactive cellulose for use in the manufacture of cellulose acetate having superior clarity by mercerizing hardwood cellulosic material and reacting it with an hydroxyalkylating agent to a degree of molar substitution ranging from 0.04 to 0.15 per anhydroglucose unit in cellulose. La présente invention concerne un procédé destiné à la production de cellulose réactive utilisée dans la fabrication de l'acétate de cellulose présentant une pureté supérieure par la mercerisation de matériau cellulosique de feuillu que l'on fait réagir avec un agent d'hydroalkylation jusqu'à un degré de substitution molaire compris entre 0,04 et 0,15 par unité d'anhydroglucose dans la cellulose.
