The blend MEA/MDEA (5/25%wt.) was studied on the LEMEDES-CO2 lab-scale pilot plant, with representative conditions of post-combustion CO2 capture for power generation during 900 h. CO2 loadings were determined and showed average values of 0.12 and 0.40 respectively for the lean and rich solvents. Stability of the two amines, namely MEA and MDEA, was monitored using ionic chromatography; results did not show any significant degradation of MDEA during the campaign, in contrary to MEA which showed a significant degradation in the range of 0.03 points per day. Analytical methods involving GC?MS and IC were developed in order to identify potential degradation products in the liquid phase of the solvent. Study of the gaseous emissions? composition was also realized using sampling on different solid sorbents followed by thermal desorption and GC?MS analysis. A total of 22 compounds were listed including amines, organic acids, and pyrazines derivatives. 12 degradation products were found in the solvent itself and 11 in the treated flue gas among which MDEA, the constituent amine of the blend. A quantitative monitoring was carried out for formic and oxalic acids. Results showed concentrations reaching 500 mg/L for oxalic acid and 1400 mg/L for formic acid.

A pilot plant campaign was performed to study MEA degradation in CO2 capture conditions and anticipate potential degradation products emissions to the atmosphere in industrial case. Aqueous 30% wt MEA was cycled between absorption and regeneration steps during 1700 h in the presence of a synthetic flue gas containing 81% of N2, 14% of CO2, 5% of O2, 97 ppm of NO, 9 ppm of SO2 and 5 ppm of NO2. Specific methods (sampling, sample conditioning and analysis) were developed to improve degradation products identification and to provide a quantification of targeted compounds in liquid phase and above all in absorber and stripper gas effluents. Especially, trace elements were detected in liquid phase thanks to Head Space-Solid Phase MicroExtraction (HS-SPME) and liquid-liquid extraction with ChemElut cartridges and in gas phase thanks to adsorbent tubes of different type: Sep-Pak for aldehydes and ketones, Orbo 60 for N-nitrosodimethylamine, Tenax and active charcoal for non-specific adsorption. 32 degradation products were identified in liquid phase and 38 in gas phase, 17 of which for the first time, especially derivatives of pyridine and oxazolidine, 1H-pyrrole and a new nitrosamine, the N-nitroso-2-methyl-oxazolidine.

What a catch! Basic ionic liquids (ILs) based on a phosphonium hydroxide derivative can be tuned for CO2 capture by varying the weak proton donors, which have different pKa values. The stability, absorption capacity, and absorption enthalpy of the ILs could be easily tuned: the best IL for CO2 capture has good stability (>300 C), energy saving (ca. 56kJ mol-1), and equimolar absorption capability.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Synthetic Route of 497-25-6, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 497-25-6, Name is Oxazolidin-2-one, molecular formula is C3H5NO2

A series of C5-substituted 1,2,4-triaryl-1H-imidazoles was synthesized. Their gene-activating properties were determined on estrogen receptor alpha positive MCF-7 breast cancer cells, stably transfected with the plasmid ERE wtcluc (MCF-7-2a cells). The influence of 4-OH and 2-Cl substituents on the phenyl rings as well as the significance of a methyl, ethyl, or phenyl group at C5 on the estrogen receptor binding and the resulting gene activation in MCF-7-2a cells was studied. The alkyl and aryl groups at C5 of 1,2,4-tris(4-hydroxyphenyl)-1H-imidazole 1 increased the transactivation, while chlorine atoms on the phenyl rings diminished this effect. 5-Ethyl-1,2,4-tris(4- hydroxyphenyl)-1H-imidazole 9 was identified as the most active compound. Its excellent transcriptional activity did not only depend on the C5 ethyl group, but also on the three hydroxyl groups of the phenyl rings. Compounds (11-14) with a reduced number of hydroxyl groups displayed distinctly lower gene activation.

The synthesis of isocyanurate-free, linear poly(oxazolidin-2-one)s starting from diepoxides and aromatic as well as aliphatic diisocyanates is reported. N-Heterocyclic carbenes (NHCs), liberated in situ from thermally labile CO2 adducts, in combination with Lewis acids of the simplest kind (metal halides such as LiCl and MgCl2) were employed in a cooperative manner to prepare linear polymers with molecular weights (Mn) ranging from 6 to 50 kg/mol. Crucially, it is demonstrated that action of either NHC (Lewis base) or metal halide (Lewis acid) alone entails the formation of significant amounts of trimerized isocyanates (isocyanurate) and concomitant gelling of the thus cross-linked material, highlighting the advantages of a cooperative, dual catalytic approach. Reactions were conducted at 200 C with low NHC loadings (0.5 mol %) to deliver isolated yields of 60-90% within 3-8 h polymerization time. Investigations regarding regioselectivity revealed that exclusively 5-substituted oxazolidin-2-one was formed. Notably, these transformations can be catalyzed by a combination of 1,3-dimethylimidazolium-2-carboxylate, a readily accessible and robust NHC-precursor tolerant toward atmospheric conditions, and well-available LiCl. A mechanism is proposed whereby the high molecular weights and the selectivity for oxazolidinone formation over side reactions are attributed to the high nucleophilicity of the NHC, cooperative monomer activation by the metal halide, and specifically chosen reaction conditions.

Rice beer is traditionally prepared and consumed by various ethnic populations in the Southeast Asian countries. To understand the probable effects of rice beer on human health, present research was aimed to study biochemical parameters, microbial diversity and metabolites of major rice beer varieties of Assam, namely Apong (Poro and Nogin), Xaaj and Joubishi. Alcoholic content of rice beer varieties varied from 9.41 to 19.33% (v/v). Free radical scavenging activity against DPPH· and ABTS+ were 1.94?4.14 and 1.69?3.91 mg of ascorbic acid/ml of rice beer, respectively. In relation to antioxidant activities, phenolic content varied from 2.07 to 5.40 mg gallic acid/ml of rice beer. Next-generation sequencing of 16S rDNA showed that 18 genera of bacteria were present irrespective of rice beer varieties in which lactic acid bacteria were the dominant group (90% abundance). Functional predictions based on the bacterial profiles indicated pathways, such as metabolisms of carbohydrate, amino acid, vitamins and cofactors, and xenobiotic biodegradation, to be active in the rice beer varieties. Out of 18 core bacterial genera, 7 had correlations with the predicted functions. Gas chromatography and mass spectroscopy-based metabolite analysis revealed that the metabolite profiles of the rice beer varieties consisted of 18 saccharides, 18 organic acids, 11 sugar alcohols, 8 amino acids, 1 vitamin and nutraceutical compounds thiocoumarine, carotene, oxazolidine-2-one and acetyl tyrosine. Due to the presence of potent prebiotics, probiotics and nutraceuticals, rice beer may have health benefits which need to be studied further.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Synthetic Route of 497-25-6, you can also check out more blogs about497-25-6

A practical and expedient synthesis of the titled compounds is described. Using the same simple procedure (DBU was reacted with the mixture of an alkynol and a nitrogen heterocycle in CH2Cl2 at rt for 16 h), a wide variety of diverse NH-containing nucleophiles such as pyrazoles, indazoles, indoles, imidazoles and benzoimidazole, oxazolidinone and benzooxazolone, triazoles, phthalimides, and N-formyl anilines, have been reacted with 4-aryl-4-hydroxy-alkynyl esters to afford good yields of desired products. This reaction proceeded by the DBU catalyzed redox isomerization of ethyl 4-aryl-4-hydroxybut-2-ynoate to (E)-ethyl 4-aryl-4-oxobut-2-enoate, followed by the DBU catalyzed aza-Michael reactions with the isomerized product in one-pot.
