Abstract

A facile method was adopted to perform succinylation of cellulose using succinic anhydride and a reactive extrusion process in the presence of ionic liquid (IL), 1-butyl-3-methylimidazolium chloride [Bmim]Cl. Succinylated cellulose with a degree of substitution (DS) in the range of 0.166–0.245 was obtained. Upon characterization, the existence of succinylation between cellulose and succinic anhydride was confirmed.
