Cellulose has been identified as the most abundant renewable material but however utilization of cellulose is still limited, it does not dissolve in most convectional solvents. This study focusses on cellulose dissolution using ionic liquids namely: 1-butyl-3-methylimidazolium chloride ([BMIM][Cl]), 1-allyl-3-methylimidazolium chloride ([AMIM][Cl]) and 1-butyl-3-methylpyridinium chloride ([BMPy][Cl]) with N, N-dimethylformamide co-solvent. The solubility of the cellulose was tested in pure ILs as well as in solution of ILs/DMF. Results showed that solubility of the cellulose in ILs greatly enhanced in the presence of DMF. The complete dissolution of cellulose in both the systems such as pure ILs and ILs/DMF was also evident by d. (ρ), sound velocity (μ) and refractive index (nD) measurements. Furthermore, COSMO-RS anal. was also performed in order to achieve a better understanding of the mol. interactions between the ILs and the co-solvent. In addition to the above theor. chem. tools, natural bond orbital (NBO), fragment MO (FMO) and chem. reactivity analyzes for cellulose mol. was investigated. Theor. data obtained proved that cellulose mol. is more reactive than glucose. In addition, this study also deals with the regeneration of the cellulose from dissolved solution using deionized water. The regenerated cellulose was characterized by fourier transform IR spectroscopy, X-ray diffraction, SEM, thermogravimetric anal. and differential scanning calorimetry techniques. It was observed that the cellulose regenerated cellulose from both solvent systems hold excellent mech. properties. In the experiment, the researchers used many compounds, for example, 1-Butyl-3-methylpyridinium Chloride (cas: 125652-55-3Quality Control of 1-Butyl-3-methylpyridinium Chloride).
1-Butyl-3-methylpyridinium Chloride (cas: 125652-55-3) belongs to pyridine derivatives. The pyridine ring occurs in many important compounds, including agrochemicals, pharmaceuticals, and vitamins. Pyridine derivatives are also useful as small-molecule α-helix mimetics that inhibit protein-protein interactions, as well as functionally selective GABA ligands.Quality Control of 1-Butyl-3-methylpyridinium Chloride
