In 2012,Fernandes, Debra; Conway, William; Wang, Xiaoguang; Burns, Robert; Lawrance, Geoffrey; Maeder, Marcel; Puxty, Graeme published 《Protonation constants and thermodynamic properties of amines for post combustion capture of CO2》.Journal of Chemical Thermodynamics published the findings.Reference of 2-(Piperidin-4-yl)ethanol The information in the text is summarized as follows:
The leading process for the post combustion capture (PCC) of CO2 from coal-fired power stations and hence reduction in greenhouse gases involves capture by aqueous amine solutions Of the reactions that occur in solution, which include CO2 hydration, de-protonation of carbonic acid, amine protonation and carbamate formation, the protonation of the amine in the absorber and its subsequent de-protonation in the stripper involve the greatest enthalpy changes. In this study, protonation constants (reported as log10 K prot) of selected series of primary, secondary and tertiary alkanolamines/amines over the temperature range 288-318 K are reported. Selected series studied involve primary, secondary and tertiary mono-, di- and tri-alkanolamines, secondary amines including heterocyclic species, and both -CH2OH and -CH2CH2OH substituted piperidines. van’t Hoff analyses have resulted in the standard molar enthalpies, ΔH m o, and molar entropies, ΔS m o, of protonation. Trends in ΔH m o are correlated with systematic changes in composition and structure of the selected series of amines/alkanolamines, while ΔH m o-ΔS m o plots generated linear correlations for the mono-, di-, and tri-alkanolamines, the -CH2OH and -CH2CH2OH substituted piperidines, and the alkylamines. These relationships provide a guide to the selection of an amine(s) solvent for CO2 capture, based on a greater difference in log10 K prot between the absorber and stripper temperatures In the experimental materials used by the author, we found 2-(Piperidin-4-yl)ethanol(cas: 622-26-4Reference of 2-(Piperidin-4-yl)ethanol)
2-(Piperidin-4-yl)ethanol(cas: 622-26-4) can be used to synthese ursolic acid derivatives, spiroimidazolidinone NPC1L1 inhibitors, neurokinin-2 receptor antagonists, antagonists for inhibition of platelet aggregation.Reference of 2-(Piperidin-4-yl)ethanol
