Preparation and structural characterization of lignin micro/nano-particles with ionic liquid treatment by self-assembly

Abstract: Abstract. In the present research, 1,3-dimethyl-imidazolium dimethyl phosphate ([Mmim][DMP]) ionic liquid was applied to dissolve alkali lignin from wheat grass to prepare for lignin micro/nano-particles. The alkali lignin can be dissolved completely at 80°C in 30 min under microwave condition with [Mmim][DMP] (solid-liquid ratio of 1:10) which is easy to be recycled. The dissolved lignin can be precipitated by diluting the ionic liquid-lignin solution with water to get lignin micro/nano-particles with diamete… Show more

“…Such technology could foster the utilization of lignocellulosic residues and the use of naoncellulose [242]. Ionic liquids were also used for the preparation of lignin nanoand micro-spheres by dissolving alkali lignin in [MMIM][DEP] followed by a gradual regeneration in water [243].…”

“…Lignin is one of the most abundant natural biopolymers in the world, which accounts for about 15-40 wt% of lignocellulosic biomass [13]. It is a three-dimensional and highly crosslinked macromolecule as a renewable source of aromatic and chemical feedstock [97]. Lignin is a complex aromatic biopolymer typically deriving from three different monolignol units, coniferyl alcohol, sinapyl alcohol, and coumaryl alcohol [98] (Figure 1.5).…”
