Supported by increasingly available reserves, natural gas is achieving greater adoption as a cleaner-burning alternative to coal in the power sector. As a result, carbon capture and sequestration from natural gas-fired power plants is an attractive strategy to mitigate global anthropogenic CO2 emissions. However, the separation of CO2 from other components in the flue streams of gas-fired power plants is particularly challenging due to the low CO2 partial pressure (?40 mbar), which necessitates that candidate separation materials bind CO2 strongly at low partial pressures (?4 mbar) to capture ?90% of the emitted CO2. High partial pressures of O2 (120 mbar) and water (80 mbar) in these flue streams have also presented significant barriers to the deployment of new technologies for CO2 capture from gas-fired power plants. Here, we demonstrate that functionalization of the metal-organic framework Mg2(dobpdc) (dobpdc4- = 4,4?-dioxidobiphenyl-3,3?-dicarboxylate) with the cyclic diamine 2-(aminomethyl)piperidine (2-ampd) produces an adsorbent that is capable of ?90% CO2 capture from a humid natural gas flue emission stream, as confirmed by breakthrough measurements. This material captures CO2 by a cooperative mechanism that enables access to a large CO2 cycling capacity with a small temperature swing (2.4 mmol CO2/g with DeltaT ? 100 C). Significantly, multicomponent adsorption experiments, infrared spectroscopy, magic angle spinning solid-state NMR spectroscopy, and van der Waals-corrected density functional theory studies suggest that water enhances CO2 capture in 2-ampd-Mg2(dobpdc) through hydrogen-bonding interactions with the carbamate groups of the ammonium carbamate chains formed upon CO2 adsorption, thereby increasing the thermodynamic driving force for CO2 binding. In light of the exceptional thermal and oxidative stability of 2-ampd-Mg2(dobpdc), its high CO2 adsorption capacity, and its high CO2 capture rate from a simulated natural gas flue emission stream, this material is one of the most promising adsorbents to date for this important separation.

In this study, we systematically investigated 39 secondary amines as additives in concentrated EB/NMP solutions for gelation and degradation. We discovered that when both the width (defined as the longest distance between two hydrogens in the plane perpendicular to the NH bond of the amine) and depth (defined as the longest distance between two atoms in a plane perpendicular to the width) of the amines are <4.53 A and their pKa is >7.7, the amines significantly extend the gelation times of 20 mass % EB/NMP solutions for more than 12 h. However, some of these amines also significantly degrade the polymer. Amines with small width and depth and strong basicity, such as azetidine and pyrrolidine, can significantly destroy the EB structures. This was evidenced by order-of-magnitude decreases in doped film conductivity, by significantly changed UV-vis spectra, and by significantly reduced molecular weights of the aged EB solutions as measured by gel permeation chromatography (GPC). However, when both the width and depth of amines are >4.53 A, these amines neither prolong gelation time nor appreciably degrade EB.

Previously reported pyrrolones, such as TDR32570, exhibited potential as antimalarial agents; however, while these compounds have potent antimalarial activity, they suffer from poor aqueous solubility and metabolic instability. Here, further structure-activity relationship studies are described that aimed to solve the developability issues associated with this series of compounds. In particular, further modifications to the lead pyrrolone, involving replacement of a phenyl ring with a piperidine and removal of a potentially metabolically labile ester by a scaffold hop, gave rise to derivatives with improved in vitro antimalarial activities against Plasmodium falciparum K1, a chloroquine- and pyrimethamine-resistant parasite strain, with some derivatives exhibiting good selectivity for parasite over mammalian (L6) cells. Three representative compounds were selected for evaluation in a rodent model of malaria infection, and the best compound showed improved ability to decrease parasitaemia and a slight increase in survival.

Because enzymes can increase reaction rates by enormous factors and tend to be very specific, category: piperidines, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 50541-93-0

Highly effective decontamination of nitrophenols from aqueous solution is a challenge for public health and ecosystem protection. Here we report the assembly of UiO-66 onto Fe3O4 particles by solvothermal method, formed durian-shaped magnetic porous composites (MSU(Zr)) with multi-core-shell structure. The weight ratio of UiO-66 shells and the Fe3O4 multi-core is about 6:4. MSU(Zr) performed well on 2-nitroresorcinol (NRC) adsorption, which could be attributed to the highly porosity and the nature of Lewis base of Zr6O4(OH)4 clusters. The equilibrium adsorption capacity for NRC is more than 200 mg g?1, which means that each Zr6O4 centre can uptake more than three NRC molecules (MSU(Zr)·3NRC). Kinetic parameters follow pseudo-second-order kinetics and Langmuir isotherm. pH value plays a significant role on NRC adsorption, which is more favor at acidic condition. It’s remarkable that the reversible adsorption-desorption performance could be adjust with pH. The reusability of MSU(Zr) shows a good recyclability that the adsorption capacity is still more than 180 mg g?1 after five regeneration cycles.
