The potential of 1-butyl-3-methylpyridinium chloride, [Bmpy][Cl], as a pretreatment solvent for lignocellulosic biomasses, bagasse and Eucalyptus, was investigated. The yields of regenerated biomasses ranged between 35% and 96%, and varied according to the pretreatment time, type of ionic liquid (IL) and biomass. The pretreatment of the biomass with [Bmpy][Cl] resulted in up to 8-fold increase in the cellulose conversion when compared with the untreated biomass. For a short pretreatment period (i.e., 10 min), [Bmpy][Cl] showed better performance than 1-ethyl-3-methylimidazolium acetate ([Emim][OAc]) with respect to the initial enzymic saccharification rates. The increase in the reaction rates with [Emim][OAc] treatment was because of a reduction in the cellulose crystallinity. In contrast, a decrease in the crystallinity index was not clearly observed for the biomass pretreated with [Bmpy][Cl], and the enhancement of the enzymic saccharification rates using this IL is presumably due to a reduction in the d.p. of cellulose in the biomass. In the experiment, the researchers used many compounds, for example, 1-Butyl-3-methylpyridinium Chloride (cas: 125652-55-3Safety of 1-Butyl-3-methylpyridinium Chloride).
1-Butyl-3-methylpyridinium Chloride (cas: 125652-55-3) belongs to pyridine derivatives. Pyridine has a conjugated system of six π electrons that are delocalized over the ring. The molecule is planar and, thus, follows the Hückel criteria for aromatic systems. Pyridine, its benzo and pyridine-based compounds play diverse roles in organic chemistry. Pyridine-based materials are valued for their optical and physical properties as well as their medical potential. Safety of 1-Butyl-3-methylpyridinium Chloride
