Preparation of nanocellulose by hydrolysis with ionic liquids and two-step
hydrolysis with ionic liquids and enzymes
The aim of this study was to compare parameters of nanocellulose obtained by two different procedures:
hydrolysis with ionic liquids (1-allyl-3-methylimidazolium chloride and 1-ethyl-3-methylimidazolium acetate) and
hydrolysis with ionic liquids in combination with hydrolysis using a cellulolytic enzyme from Trichoderma reesei.
Avicel cellulose was treated with two ionic liquids: 1-allyl-3-methylimidazolium chloride (AmimCl) and 1-ethyl 3-methylimidazolium acetate (EmimOAc). In the two-step hydrolysis cellulose after treatment with ionic liquids
was additionally hydrolyzed with a solution of enzymes. In order to characterize the obtained material, the
following analyses were used: infrared spectroscopy, X-ray diffraction and dynamic light scattering. The results
indicated that cellulose obtained by two-step nanocellulose production methods (first hydrolysis with ionic liquids
and then with enzymes) showed similar parameters (particle size, XRD patterns and degree of crystallinity) as the
material after the one-step process, i.e. hydrolysis with ionic liquids.
