Interactions of ionic liquids with polysaccharides – 7: Thermal stability of cellulose in ionic liquids and N-methylmorpholine-N-oxide was written by Dorn, Susann;Wendler, Frank;Meister, Frank;Heinze, Thomas. And the article was included in Macromolecular Materials and Engineering in 2008.Name: 1-Butyl-3-methylpyridinium Chloride This article mentions the following:
The thermal behavior of cellulose dissolved in ionic liquids (IL) was studied and compared N-methylmorpholine-N-oxide (NMMO) solutions The cellulose solutions were characterized by reaction calorimetry and UV-visible spectroscopy. Generation of chromophoric substances in cellulose/IL solutions is minimized heating at >100° for longer time periods. Dynamic calorimetric investigations revealed thermal activity at >180° with 1-ethyl-3-methylimidazolium acetate and at >200° with 1-butyl-3-methylimidazolium chloride and five other IL. Moreover, even in the case of modified cellulose/IL solutions, e.g., activated charcoal, only a slight decline of onset temperatures was registered compared to modified cellulose/NMMO solutions In the experiment, the researchers used many compounds, for example, 1-Butyl-3-methylpyridinium Chloride (cas: 125652-55-3Name: 1-Butyl-3-methylpyridinium Chloride).
1-Butyl-3-methylpyridinium Chloride (cas: 125652-55-3) belongs to pyridine derivatives. Pyridines are an important class of heterocycles and occur in polysubstituted forms in many naturally occurring biologically active compounds, drug molecules and chiral ligands. Several pyridine derivatives play important roles in biological systems. While its biosynthesis is not fully understood, nicotinic acid (vitamin B3) occurs in some bacteria, fungi, and mammals.Name: 1-Butyl-3-methylpyridinium Chloride
