Imidazole, a new tunable reagent for producing nanocellulose, part I: Xylan-coated CNCs and CNFs
Mao, Jia; Abushammala, Hatem; Hettegger, Hubert; ETAL.. (Multidisciplinary Digital Publishing Institute, 2017-10)Imidazole is reported to be an effective reactant for the production of nanocellulose from hardwood pulp. The morphologies and surface properties of the nanocellulose can be simply tailored according to the water content ... -
On the mechanism of the unwanted acetylation of polysaccharides by 1,3-dialkylimidazolium acetate ionic liquids: part 1—analysis, acetylating agent, influence of water, and mechanistic considerations
Zweckmair, Thomas; Hettegger, Hubert; Abushammala, Hatem; Bacher, Markus; ETAL.. (Springer, 2015-09)The acetylating action of ionic liquids frequently used in biomass and polysaccharide processing, namely 1,3-dialkylimidazolium acetates, on cellulose has been studied. Analysis was based on an accurate method to quantify ... -
On the mechanism of the unwanted acetylation of polysaccharides by 1,3-dialkylimidazolium acetate ionic liquids: part 2—the impact of lignin on the kinetics of cellulose acetylation
Abushammala, Hatem; Hettegger, Hubert; Bacher, Markus; ETAL.. (Springer, 2017-10)Cellulose acetylation has been reported as a side reaction of cellulose treatment with the ionic liquid 1-ethyl-3-methylimidazolium acetate ([EMIm][OAc]) (Karatzos et al. in Cellulose 19:307–312, 2012) and other ...
