Feldman, Julian published an article about the compound: 2-Methylglutaronitrile( cas:4553-62-2,SMILESS:N#CC(C)CCC#N ).Formula: C6H8N2. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:4553-62-2) through the article.

1,3-Dicyanobutane (derived from acrylonitrile) has a higher capacity for light aromatic hydrocarbons in liquid-liquid extraction than does sulfolane. As a solvent in extractive distillation its low volatility, high thermal stability, low f.p. and high selectivity are useful. Equilibrium data and multistage extractions of a typical light catalytic reformate are reported. A light counter-solvent is effective, especially when followed by extractive distillation A combination of methods gives high purity aromatics or improved octane gasoline. A flow diagram is given for continuous cyclic operation to sep. reformate and recover the solvent.

As far as I know, this compound(4553-62-2)Formula: C6H8N2 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Deactivation during the hydrogenation of 2-methylglutaronitrile to β-picoline, published in 1994, which mentions a compound: 4553-62-2, mainly applied to hydrogenation methylglutaronitrile; glutaronitrile methyl hydrogenation; picoline preparation, Application In Synthesis of 2-Methylglutaronitrile.

A strong correlation between conversion and product selectivity was found for the production of β-picoline from 2-methylglutaronitrile in a single-stage process. The conversion had to be maintained at a very high level in order to keep the intermediates concentration low, thus preventing the formation of coke precursors by condensation reactions. The intermediates concentration on the metal surface was strongly influenced by the reaction temperature and the partial pressures. Above 598 K, the selectivity for condensation products decreased sharply, but also the overall conversion decreased. This neg. effect could be compensated by an increased hydrogen partial pressure.

This literature about this compound(4553-62-2)Application In Synthesis of 2-Methylglutaronitrilehas given us a lot of inspiration, and I hope that the research on this compound(2-Methylglutaronitrile) can be further advanced. Maybe we can get more compounds in a similar way.

Category: iodides-buliding-blocks. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 2-Methylglutaronitrile, is researched, Molecular C6H8N2, CAS is 4553-62-2, about Toward New Solvents for EDLCs: From Computational Screening to Electrochemical Validation. Author is Schuetter, Christoph; Husch, Tamara; Korth, Martin; Balducci, Andrea.

The development of innovative electrolytes is a key aspect of improving electrochem. double layer capacitors (EDLCs). New solvents, new conducting salts as well as new ionic liquids need to be considered. To avoid time-consuming “”trial and error”” experiments, it is desirable to “”rationalize”” this search for new materials. An important step in this direction is the systematic application of computational screening approaches. Via the fast prediction of the properties of a large number of compounds, for instance all reasonable candidates within a given compound class, such approaches should allow to identify of the most promising candidates for subsequent experiments In this work we consider the toy system of all reasonable nitrile solvents up to 12 heavy atoms. To investigate if our recently proposed computational screening strategy is a feasible tool for the purpose of rationalizing the search for new EDLC electrolyte materials, we correlate-in the case of EDLCs for the first time-computational screening results with exptl. findings. For this, experiments are performed on those compounds for which exptl. data is not available from the literature. We find that our screening approach is well suited to pick good candidates out of the set of all reasonable nitriles, comprising almost 5000 compounds

Organic electrosynthesis can transform the chem. industry by introducing electricity-driven processes that are more energy efficient and that can be easily integrated with renewable energy sources. However, their deployment is severely hindered by the difficulties of controlling selectivity and achieving a large energy conversion efficiency at high c.d. due to the low solubility of organic reactants in practical electrolytes. This control can be improved by carefully balancing the mass transport processes and electrocatalytic reaction rates at the electrode diffusion layer through pulsed electrochem. methods. The authors explore these methods in the context of the electrosynthesis of adiponitrile (ADN), the largest organic electrochem. process in industry. Systematically exploring voltage pulses in the timescale between 5 and 150 ms led to a 20% increase in production of ADN and a 250% increase in relative selectivity with respect to the state-of-the-art constant voltage process. Also, combining this systematic exptl. study with artificial intelligence (AI) tools allowed the authors to rapidly discover drastically improved electrosynthetic conditions, reaching improvements of 30 and 325% in ADN production rates and selectivity, resp. This powerful AI-enhanced exptl. approach represents a paradigm shift in the design of electrified chem. transformations, which can accelerate the deployment of more sustainable electrochem. manufacturing processes.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Insight into polyacrylonitrile molecular structure from calculated vibrational frequencies and infrared intensities of model oligomers, published in 1994-11-01, which mentions a compound: 4553-62-2, mainly applied to polyacrylonitrile mol vibration model oligomer; IR intensity polyacrylonitrile mol vibration, SDS of cas: 4553-62-2.

RHF/3-21G vibrational frequencies and intensities are calculated for acrylonitrile dimers (S-2-methylglutaronitrile) and pentamers differing by their conformation and/or configuration to comprehend the influence of these 2 structural characteristics on the IR spectra of polyacrylonitrile chains. The isotactic pentamer tends to adopt a (TG)3 helix while for the syndiotactic configuration, 2 conformations of similar total energy are obtained. On the basis of these structures, it is found that the calculated IR spectra follow the reported exptl. trends. Of particular interest is the theor. verification of the exptl. observation made by M. Minagawa et al. (1988) that the intensity ratio between bands at 1230 and 1250 cm-1 depends on the stereochem. structure of polyacrylonitrile and provides a measure of their isotacticity percentage.

Computed Properties of C6H8N2. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 2-Methylglutaronitrile, is researched, Molecular C6H8N2, CAS is 4553-62-2, about Anodic Dissolution of Al Current Collectors in Unconventional Solvents for High Voltage Electrochemical Double-Layer Capacitors. Author is Krummacher, Jakob; Hess, Lars-Henning; Balducci, Andrea..

This study studied the anodic dissolution of Al current collectors in unconventional electrolytes for high voltage electrochem. double-layer capacitors (EDLCs) containing adiponitrile (ADN), 3-cyanopropionic acid Me ester (CPAME), 2-methyl-glutaronitrile (2-MGN) as solvent, and Et4N+ tetrafluoroborate (Et4NBF4) and Et4N+ bis(trifluoromethanesulfonyl)imide (Et4NTFSI) as conductive salts. To have a comparison with the state-of-the-art electrolytes, the same salts were also used in combination with MeCN (ACN). The chem.-phys. properties of the electrolytes were studied. Also, their impact on the anodic dissolution of Al was analyzed in detail as well as the influence of this process on the performance of high voltage EDLCs. The results of this study indicated that in the case of Et4NBF4-based electrolytes, the use of an alternative solvent is very beneficial for the realization of stable devices. When Et4NTFSI is used, the reduced solubility of the complex Al(TFSI)3 appears to be the key for the realization of advanced electrolytes.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 4553-62-2, is researched, Molecular C6H8N2, about Approaches to Electrolyte Solvent Selection for Poly-Anthraquinone Sulfide Organic Electrode Material, the main research direction is polyanthraquinone sulfide organic electrode material electrolyte solvent selection; Hansen parameters; organic batteries; organic electrode; polyanthraquinone; solubility.Recommanded Product: 4553-62-2.

Organic materials such as polyanthraquinone sulfide (PAQS) are receiving increased attention as electrodes for energy storage systems owing to their good environmental compatibility, high rate capability, and large charge-storage capacity. However, one of their limitations is the solubility in organic solvents typically composing the electrolytes. Here, the solubility of PAQS was tested in 17 different solvents using UV/Vis spectroscopy. The results show that PAQS exhibits a very wide range of solubility according to the nature of the solvent and the obtained trend agrees well with the predictions from Hansen solubility anal. Furthermore, the transport properties (conductivity, σ, and viscosity, η) of selected electrolytes composed of non-solubilising solvents with 1 M LiTFSI are compared and discussed in the temperature range from -40 °C to 80 °C. In the second part of this study, the electrochem. characterization of PAQS as electrode material in selected pure or mixture of solvents with 1 M LiTFSI as salt was made in half-cells by a galvanostatic method. In a methylglutaronitrile (2MeGLN)-based electrolyte that exhibits low solubility of PAQS, it appears that the capacity fade is intricately linked to the large irreversibility of the second step of the redox process. Although the standard cyclic carbonate solvents mixture (ethylene carbonate and propylene carbonate) led to rapid capacity fade in the initial 10-15 cycles owing to their high solubilising ability. Finally, it is shown that a pure linear alkylcarbonate (di-Me carbonate) or binary mixture of ether-based (dioxolane/dimethoxy ethane) electrolyte is much more compatible for enhanced capacity retention in PAQS with more than 120 mAh g-1 for 1000 cycles at 4 C.
