Thermal degradation under wet conditions is considered as an important aging mechanism in polyamide 6,6 (PA 6,6). The effect of water on thermal degradation of amorphous PA 6,6 is investigated at relatively low temperatures, varying from 1000 to 2000 K, using reactive force field molecular dynamics (MD) and collective variable-driven hyperdynamics simulations. The simulation of the related long-term chemical reactions is made possible thanks to the self-learning accelerated MD concept of hyperdynamics in combination with the corresponding accurate reproduction of the correct dynamics, consistent with unbiased MD simulations. The kinetics of cleavage reactions of the amide bonds in the backbone of the polymer chains, responsible for the thermal degradation of the polymer, is studied, and the influence of water content on the activation energy and pre-exponential factor of the cleavage reactions is explored. The results show that activation energy and pre-exponential factor are in agreement with experimental data. The proposed simulation framework not only estimates kinetic properties of thermal degradation that are consistent with experimental observations but also provides a predictive tool for studying long-term thermal degradation of PA 6,6.

Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 6582-52-1, Name is 2,2′-Methylenedianiline. In a document, author is Chen, Suo, introducing its new discovery. Recommanded Product: 2,2′-Methylenedianiline.

Different levels of beeswax (B) or carnauba wax (C) were added into gelatin (G) at 5%, 10%, and 15% (w/w) to prepare films containing glycerol as a plasticizer. Although the wax addition increased the opacity and yellowness of gelatin films, both the UV/visible light and water vapor barriers were successfully improved gradually with increasing wax levels, and B was more effective than C. Addition of 10% and 15% wax significantly reduced the water solubility and WVP (P < 0.05). However, the mechanical properties of gelatin-wax films were not strengthened compared with control. As wax levels increased, the resulting films became more brittle, harder, and less stretchable. SEM showed GB films have more uniform surfaces and compact cross-sections compared with GC films. All films showed antioxidant activity against DPPH and hydroxyl radicals, and iron reducing; however, the effects obtained with the gelatin-wax films were not significantly different from the G films (P > 0.05). Based on FTIR analysis, all films showed amide absorption regions, but GB films showed higher intensity of absorption peaks for lipid functional groups than GC films. Wax addition improved thermal stability of films suggesting an interaction between wax and gelatin. The improved barrier properties and thermal stability of the gelatin-wax films suggest that they can be used to protect foods from deterioration, and B was found to be better than C when added in gelatin films.

Herein we describe the continued optimization of M-4 positive allosteric modulators (PAMs) within the 5-amino-thieno[2,3-c] pyridazine series of compounds. In this letter, we disclose our studies on tertiary amides derived from substituted azetidines. This series provided excellent CNS penetration, which had been challenging to consistently achieve in other amide series. Efforts to mitigate high clearance, aided by metabolic softspot analysis, were unsuccessful and precluded this series from further consideration as a preclinical candidate. In the course of this study, we found that potassium tetrafluoroborate salts could be engaged in a tosyl hydrazone reductive cross coupling reaction, a previously unreported transformation, which expands the synthetic utility of the methodology.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time. 6582-52-1, Name is 2,2′-Methylenedianiline, formurla is C13H14N2. In a document, author is Bjedov, Srdan, introducing its new discovery. Recommanded Product: 2,2′-Methylenedianiline.

The preparation, X-ray structure and properties of noncyclic (1) and cyclic (2) polyaza copper(II) complexes with caged moiety, and copper(II) enhanced hydrolysis of acetonitrile participated in the cyclization of 1 to 2 are reported. The average Cu-N distances of complex 1 and 2 are somewhat shorter than those of square-planar or square-pyramidal complexes of analogue [14]-membered ring copper(II) complexes. These results derived from the squeeze effect of caged moiety of bicyclononan. Reaction of formaldehyde and complex 1 in the presence of base in acetonitrile solution produced complex 2. In this catalytic route, coordination of acetonitrile onto Cu(II) ion, a Lewis acid, of complex 1 makes the electrophilicity of the carbon of nitrile increased. Absorption maximum of the complex 2 is shifted to somewhat shorter wavelength than that of the complex 1. It is supposed to the higher ligand field stabilization energy of complex 2, which has cyclized ligand, comparing that of the complex 1, which has open ligand. These complexes are stable against disproportionation in copper(I) state.

Microplastics (MPs), as reservoirs of cocktail of contaminants, impose severe impacts on human and ambient water environment. Therefore, efficient and eco-friendly MPs removal techniques are urgently needed. In this study, for the first time, magnetic carbon nanotubes (M-CNTs) have been synthesized as adsorbates to remove MPs. M-CNTs were effectively adsorbed on polyethylene (PE), polyethylene terephthalate (PET), and poly amide (PA) and all the MPs/M-CNTs composites were readily separated from aqueous solutions by magnetic force. When the 5 g.L-1 of M-CNTs was added, target MPs (5 g.L-1) were completely removed within 300 min. The maximum adsorption capacities of PE, PET and PA were 1650, 1400 and 1100 mg-M-CNTs.g(-1), respectively. This process was hardly affected by the COD, NH3-N, and PO43- substance and all MPs were completely removed from the wastewater discharged from a kitchen waste treatment plant. Furthermore, the adsorbed M-CNTs can be recycled via thermal treatment (600 degrees C) and these M-CNTs were featured with the same magnetic properties and comparable MPs removal capacity to the original ones. After being used for four times, M-CNTs were still able to remove similar to 80% of total MPs in the testing solution. The observed effectual removal of MPs from prepared solutions and wastewater highlights M-CNTs as promising techniques for the control of MPs pollution.

The effect of Alcalase hydrolysis on structure and peptide profiles of garden cress (GC) (Lepidium sativum) protein concentrate was investigated. The protein hydrolysates were characterized by gel electrophoresis, emulsifying and foaming properties, and in vitro antioxidant activity. The water holding capacity, foaming, and emulsification properties were markedly improved at 10.69% degree of hydrolysis (DH). FTIR spectroscopy revealed that %DH had a significant impact on the secondary structure of protein concentrate with a higher shift of amide I and amide II bands. A significant drop in the enthalpy (Delta H) values in the DSC endothermic peaks confirmed the hydrolysis of the protein concentrate. Antioxidant activities of GC protein concentrate were greatly improved with the DH. The obtained data suggest that moderate hydrolysis can improve the functional and antioxidant properties of protein concentrate, and therefore, the obtained protein hydrolysates could be exploited as protein supplements in the dietetic foods, infant formulae, and geriatric products.

An efficient method for preparation of secondary amides from primary amides and aldehydes using rhodium on carbon matrix as catalyst was developed. The method does not require any external hydrogen source and carbon monoxide is used as a reducing agent. The most active rhodium catalysts were characterized by BET, TEM and XPS techniques. Unexpectedly, it was found that heterogeneous rhodium on carbon matrix works as precatalyst for homogenous active species due to leaching of rhodium to the solution. Various secondary amides were synthesized and checked for antifungal activity. 4-Methoxy-N-(4-methoxybenzyl)benzamide demonstrated promising activity against Rhizoctonia Solani.

Nickel(II) Cyclen Complexes Bearing Ancillary Amide Appendages for the Electrocatalytic Reduction of CO2

Substituted cyclen complexes of nickel(II) containing either one or two pendant amide groups were prepared as potential electrocatalysts for the reduction of CO2 to CO. Four complexes bearing two amide substituents with either tert-butyl ([Ni(DMCy2tBu)](PF6)(2)), mesityl ([Ni-(DMCy2Mes)](PF6)(2)), 3,5-bis(triffuoromethyl)phenyl ([Ni-(DMCy2CF3)](PF6)(2)), or pentafluorophenyl ([Ni-(DMCy2C6F5)](PF6)) groups were all easily prepared and isolated without the need for column chromatography. Similarly, two other nickel(II) cyclen derivatives containing a single mesityl substituted amide pendant ([Ni(DMCyMes(Cl)](PF6) and [Ni(TrMCyMes)(Cl)]Cl) were also prepared. X-ray crystal structures were obtained for each of these complexes and show that the pendant amides are bound to the nickel(II) center at the core of the cyclen complexes. The amides coordinate to the central metal via either the amide oxygen or amide nitrogen atoms depending on the electronic properties of the amide group. The ability of each of the six complexes to electrochemically reduce CO2 was surveyed by voltammetric and controlled potential electrolysis (CPE) experiments. As the functional groups on the amide arms become more electron donating, the ability of the complexes to electrochemically activate CO2 improves. Of the four complexes containing two amide groups, [Ni(DMCy2tBu)](PF6)(2) and [Ni(DMCy2Mes)](PF6)(2) show the highest Faradaic efficiencies and current densities for CO production in contrast to homologues that contain amides with fluorinated ancillary groups ([Ni(DMCy2CF3)](PF6)(2) and [Ni(DMCy2C6F5)](PF6)). Ultimately, of the six cyclen complexes studied, the two that contain only a single pendant amide ([Ni(DMCyMes)(Cl)](PF6) and [Ni(TrMCyMes)(Cl)]Cl) proved to be the most active and efficient architectures for the electrocatalytic reduction of CO2 to CO. Both the [Ni(DMCyMes)(Cl)](PF6) and [Ni(TrMCyMes)(Cl)]Cl complexes were stable under the conditions of electrocatalysis and promoted the reduction of CO2 to CO with Faradaic efficiencies as high as 80%.

Transition-metal-free access to 2-aminopyridine derivatives from 2-fluoropyridine and acetamidine hydrochloride

Under catalyst-free conditions, an efficient method for the synthesis of 2-aminopyridine derivatives through the nucleophilic substitution and hydrolysis of 2-fluoropyridine and acetamidine hydrochloride has been developed. This amination uses inexpensive acetamidine hydrochloride as the ammonia source and has the advantages of a high yield, high chemoselectivity and wide substrate adaptability. The results suggest that other N-heterocycles containing fluorine substituents can also complete the reaction via these reaction conditions and yield the target products.
