Qualitative and quantitative structure activity relationships for the inhibitory effects of cationic head groups, functionalized side chains and anions of ionic liquids on acetylcholinesterase was written by Arning, Juergen;Stolte, Stefan;Boeschen, Andrea;Stock, Frauke;Pitner, William-Robert;Welz-Biermann, Urs;Jastorff, Bernd;Ranke, Johannes. And the article was included in Green Chemistry in 2008.Application In Synthesis of 1-Butyl-3-methylpyridinium Chloride This article mentions the following:

To contribute to a deeper insight into the hazard potential of ionic liquids to humans and the environment, an acetylcholinesterase (AchE) inhibition screening assay was used to identify toxicophore substructures and interaction potentials mediating enzyme inhibition. The pos. charged nitrogen atom, a widely delocalized aromatic system, and the lipophilicity of the side chains connected to the cationic head groups can be identified as the key structural elements in binding to the enzymes active site. With respect to this, the dimethylaminopyridinium, the quinolinium and the pyridinium head groups exhibit a very strong inhibitory potential to the enzyme with IC₅₀ values around 10 娓璏. In contrast, the polar and non-aromatic morpholinium head group is found to be only weakly inhibiting to the enzyme activity, with IC₅₀ values > 500 娓璏. The introduction of polar hydroxy, ether or nitrile functions into the alkyl side chain is shown to be a potent structural alteration to shift the corresponding ionic liquids to a lower inhibitory potential. Supporting this fact, for a series of imidazolium cations, a QSAR correlation was set up by the linear regression of the log IC₅₀ vs. the logarithm of the HPLC-derived lipophilicity parameter k₀. Addnl., a broad set of anion species (inorganic, organic and complex borate anions), commonly used as ionic liquid counterions, was tested and the vast majority exhibited no effect on AchE. Only the fluoride and fluoride containing anion species which readily undergo hydrolytic cleavage can be identified to act as AchE inhibitors. In the experiment, the researchers used many compounds, for example, 1-Butyl-3-methylpyridinium Chloride (cas: 125652-55-3Application In Synthesis of 1-Butyl-3-methylpyridinium Chloride).

Powerful peracetic acid-ionic liquid pretreatment process for the efficient chemical hydrolysis of lignocellulosic biomass was written by Uju;Goto, Masahiro;Kamiya, Noriho. And the article was included in Bioresource Technology in 2016.Category: pyridine-derivatives This article mentions the following:

The aim of this work was to design a new method for the efficient saccharification of lignocellulosic biomass (LB) using a combination of peracetic acid (PAA) pretreatment with ionic liquid (IL)-HCl hydrolysis. The pretreatment of LBs with PAA disrupted the lignin fractions, enhanced the dissolution of LB and led to a significant increase in the initial rate of the IL-HCl hydrolysis. The pretreatment of Bagasse with PAA prior to its 1-butyl-3-methylimidazolium chloride ([Bmim][Cl])-HCl hydrolysis, led to an improvement in the cellulose conversion from 20% to 70% in 1.5 h. Interestingly, the 1-butyl-3-methylpyridium chloride ([Bmpy][Cl])-HCl hydrolysis of Bagasse gave a cellulose conversion greater than 80%, with or without the PAA pretreatment. For LB derived from seaweed waste, the cellulose conversion reached 98% in 1 h. The strong hydrolysis power of [Bmpy][Cl] was attributed to its ability to transform cellulose I to II, and lowering the d.p. of cellulose. In the experiment, the researchers used many compounds, for example, 1-Butyl-3-methylpyridinium Chloride (cas: 125652-55-3Category: pyridine-derivatives).

In the last decade, the transformation of lignocellulosic biomass into biofuel through a sugar platform has been an active research subject due to depletion of fossil fuel sources. Total reducing sugars (TRS) obtained from lignocellulosic materials are considered intermediates for the preparation of various valuable chem. compounds In this work, pyridinium based ionic liquids were synthesized and utilized for the dissolution of cellulose and further conversion to TRS in the presence of metal salts as catalysts. The prepared ILs were characterized using ¹H NMR and evaluated for the dissolution of cellulose and found that [C₄C₁Py][Cl] is the best solvent to dissolve it up to 28% at 110 鎺矯. Optical microscopy in conjunction with FTIR, SEM, XRD and TGA analyzes were employed to monitor dissolution phenomenon and ascertain structural changes in regenerated cellulose. SEM results showed disrupted flaky construction for regenerated cellulose. The thermal stability decreased for regenerated cellulose as observed by TGA anal. This desirable change in cellulose after IL pretreatment was utilized to facilitate metal salts based on the catalytic conversion of cellulose to TRS. Among metal salts, CoCl₂ was identified as the best one to generate the highest yield of TRS i.e. 78% at 110 鎺矯 for 4 h. Various reaction conditions like time, temperature, and catalyst loading were optimized for catalytic conversion. The optimum conditions were observed at 4 h treatment time, 120 鎺矯 and 12% catalyst loading.

P.. And the article was included in Fluid Phase Equilibria in 2016.Category: pyridine-derivatives This article mentions the following:

Looking for a better knowledge concerning water and ionic liquids (ILs) interactions, a systematic study of the activity coefficients of water in pyridinium, pyrrolidinium and piperidinium-based ILs at 298.2 K is here presented based on water activity measurements. Addnl., the study of the structural effects of the pyridinium-based cation is also pursued. The results show that non-aromatic ILs are interacting more with water than aromatic ones, and among the ortho, meta and para isomers of 1-butyl-methylpyridinium chloride, the ortho position confers a more hydrophilic character to that specific IL. The phys.-chem. of the solutions was interpreted based on dissociation constants, natural bond orbitals and excess enthalpies providing a sound basis for the interpretation of the exptl. observations. These results show that hydrogen bonding controls the behavior of these systems, being the anion-water one of the most relevant interactions, but modulated by the anion-cation interactions.

Constantly decreasing fossil resources and exceeding energy demands are the most alarming concerns nowadays. The only way out is to develop efficient, safe, and economical biomass processing protocols that can lead toward biofuels and fine chems. This research is one of such consequences involving the deconstruction and conversion of wheat straw carbohydrate constituents into reducing sugars via one-pot reaction promoted by Lewis acidic pyridinium-based ionic liquids (PyILs) mixed with different metal salts (MCl). Various parameters such as the type of metal salt, loading amount of metal salt, time, temperature, particle size of biomass, and water content which affect the deconstruction of wheat straw have been evaluated and optimized. Among the studied ionic liquid (IL) and metal salt systems, the best results were obtained with [BMPy]+CoCl-3. The dinitrosalicylic acid (DNS) assay was used to determine the percentage of total reducing sugars (TRS) generated during treatment of wheat straw. The deconstructed wheat straw was characterized with various anal. tools, i.e., Fourier transform IR (FTIR) spectroscopy, SEM (SEM), and X-ray powder diffraction (XRD) analyses.

Investigation of reaction conditions in the synthesis of imidazolium, pyridinium and pyrrolidinium based ionic liquids was written by Adibi, M.;Mehdizadeh, A.;Ahmadi, A. N.. And the article was included in Pazhuhesh Naft in 2009.Recommanded Product: 125652-55-3 This article mentions the following:

Unique properties of ionic liquids such as low vapor pressure, high thermal stability, and their ability to dissolve polar compounds makes them potential alternatives for organic solvents lacking such characteristics. Studies show that substantial efforts are being made to synthesize these ionic liquids under milder reaction conditions. Quaternary imidazolium, pyridinium, and pyrrolidinium based salts are unfortunately prepared at high temperatures over long periods of time, making the syntheses economically inefficient. Parameters involved in the synthesis of each of these salts have been optimized in this work and the synthesis conditions have been compared. Results indicate that the synthesis of dialkyl imidazolium chlorides I (R = n-C₄H₉, n-C₆H₁₃, n-C₈H₁₇) gives higher yields and requires shorter reaction times in comparison with the other two groups.

Candida rugosa lipase (CRL) was immobilized on an eco-friendly support poly(3-hydroxybutyrate-co-hydroxyvalerate) (PHBV), by phys. adsorption, using different ionic liquids (ILs) as immobilization additives. This was to investigate the influence of cationic core ([C₄mpy]Cl, [C₄min]Cl), of anions ([C₄min]Cl, [C₄min]N(CN)₂, [C₄min]Tf₂N), and of cation chain length ([C₂min]Tf₂N, [C₄min]Tf₂N) in the immobilization process. The immobilized biocatalysts (IB) were characterized with respect to the morphol., physico-chem. properties, total activity recovery yield (Ya), and biochem. properties of more efficient IB were evaluated. Initially, it was found that the change of cationic core did not influence Ya compared to the control. With change of anions, it was seen that the best result was obtained for the more hydrophobic anion (Tf₂N), and finally increasing the cation chain length increased Ya. IB most efficient with [C₄min]Tf₂N obtained 78 % of Ya, more than twice the control value (30 %) and a considerable enhancement of operational stability compared with the control.
