We have studied the cluster structure of 1-butyl-3-methylimidazolium halide, bmimX (X = Cl, Br, I), in methanol solution by means of an electrospray mass spectrometer, which is specially designed for analysis of clusters isolated from solution. In positive ion mode experiments, the ratio of solvated bmim(+), bmim(+)(MeOH)(n) and ion-pair clusters, bmim(bmim(+)X(-))(m) was dependent on the count...

Porous cellulose aerogel materials are attracting increasing interest due to their promising potential in multiple fields. In this paper, highly porous and mechanically strong cellulose aerogels were successfully prepared from microcrystalline cellulose and dissolving pulp in ionic liquid BmimCl via a sol–gel polymerization method. The surface morphology and physical properties were characteriz...

Abstract To investigate the effect of cellulose matrix on diffusion and conductivity properties ionogels formed with BMIMCl ionic liquid (IL), two types samples were made micro (CMC) nano (CNC) cellulose. The interactions IL studied by 1 H 13 C NMR solid-state spectroscopy. cation [BMIM] + self-diffusion coefficient was calculated based Fast Field Cycling relaxation measurements. measured therm...

Abstract In this study, we treated microcrystalline cellulose (MCC) with the ionic liquid (IL) 1-butyl-3-methylimmidazolium chloride (BMIMCl) to elucidate effects that IL treatment conditions have on properties of amorphized (AC). Analysis X-ray diffractograms confirmed after 20 min AC crystallinity was reduced from 77.7 57.1%. After 10 h treatment, decreased 29.6%. Chemical and morphological c...

In this research, the new separation method based on micro solvent cluster extraction and preferential solvation has been described. A proposed separation method using aqueous mixed solvents of organic solvents (acetonitrile, 1-propanol, 2-propanol and 1,1,1,3,3,3-hexafluoro-2-propanol) or ionic liquids and an open tubular capillary has been separated the model compounds (2-naphthol, 4-nitroani...

Cellulose-graft-poly(p-dioxanone) copolymers (cellulose-g-PPDO) were homogeneously prepared via ring-opening graft polymerization (ROP) between p-dioxanone (PDO) and hydroxyl groups of cellulose using the catalyst 4-dimethylaminoptridine (DMAP) in the ionic liquid 1-butyl-3methylimidazolium chloride (BmimCl). Chemical structures and physical properties of the cellulose-g-PPDO copolymers were ch...
