In 2014,Seo, Samuel; Simoni, Luke D.; Ma, Mengting; DeSilva, M. Aruni; Huang, Yong; Stadtherr, Mark A.; Brennecke, Joan F. published 《Phase-Change Ionic Liquids for Postcombustion CO2 Capture》.Energy & Fuels published the findings.Recommanded Product: 3-(Trifluoromethyl)-1H-pyrazole The information in the text is summarized as follows:
Phase-change ionic liquids, or PCILs, are salts that are solids at normal flue gas processing temperatures (e.g., 40-80°) and that react stoichiometrically and reversibly with CO2 (one mole of CO2 for every mole of salt at typical postcombustion flue gas conditions) to form a liquid Thus, the m.p. of the PCIL-CO2 complex is below that of the pure PCIL. A new concept for CO2 separation technol. that uses this key property of PCILs offers the potential to significantly reduce parasitic energy losses incurred from postcombustion CO2 capture by using the heat of fusion (ΔHfus) to provide part of the heat needed to release CO2 from the absorbent. The phase transition yields almost a step-change absorption isotherm, so only a small pressure or temperature swing is required between the absorber and the stripper. Using aprotic heterocyclic anions (AHAs), the enthalpy of reaction with CO2 can be readily tuned, and the phys. properties, such as m.p., can be adjusted by modifying the alkyl chain length of the tetra-alkylphosphonium cation. Here, the authors present data for 4 tetrabutylphosphonium salts that exhibit PCIL behavior, as well as detailed measurements of the CO2 solubility, phys. properties, phase transition behavior, and H2O uptake for tetraethylphosphonium benzimidazolide ([P2222][BnIm]). The process based on [P2222][BnIm] has the potential to reduce the amount of energy required for the CO2 capture process substantially compared to the current technol. that employs aqueous monoethanolamine (MEA) solvents. The experimental part of the paper was very detailed, including the reaction process of 3-(Trifluoromethyl)-1H-pyrazole(cas: 20154-03-4Recommanded Product: 3-(Trifluoromethyl)-1H-pyrazole)
3-(Trifluoromethyl)-1H-pyrazole(cas: 20154-03-4) belongs to pyrazoles. Pyrazole derivatives have been reported to exhibit a wide range of applications in medicinal chemistry and pharmacology. A large number of drugs incorporating pyrazole structure have been utilized as partial agonists for nicotinic acid receptors, antidepressants, antimicrobial agents, antiviral agents, and antifungal agents solely or along with the combination of other structural motifs.Recommanded Product: 3-(Trifluoromethyl)-1H-pyrazole
