In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called A gram-negative bacterium producing a heat-stable nitrilase highly active on aliphatic dinitriles, published in 1999-11-30, which mentions a compound: 4553-62-2, Name is 2-Methylglutaronitrile, Molecular C6H8N2, Application In Synthesis of 2-Methylglutaronitrile.

A Gram-neg. bacterial strain, identified as Acidovorax facilis strain 72W, has been isolated from soil by enrichment using 2-ethylsuccinonitrile as the sole nitrogen source. This strain grows on a variety of aliphatic mono- and dinitriles. Experiments using various heating regimes indicate that nitrile hydratase, amidase and nitrilase activities are present. The nitrilase is efficient at hydrolyzing aliphatic dinitriles to cyanoacid intermediates. It has a strong bias for C3-C6 dinitriles over mononitriles of the same chain length. Whole, resting cell hydrolysis of 2-methylglutaronitrile results in 4-cyanopentanoic acid and 2-methylglutaric acid as the major products. Heating, at least 20 min at 50°C, eliminates nitrile hydratase and amidase activities, resulting in greater than 97% selectivity to 4-cyanopentanoic acid. The nitrilase activity has good heat stability, showing a half-life of 22.7 h at 50°C and a temperature optimum of at least 65°C for activity. The strain has been deposited as ATCC 55746.

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 2-Methylglutaronitrile(SMILESS: N#CC(C)CCC#N,cas:4553-62-2) is researched.Application In Synthesis of 2-Methylglutaronitrile. The article 《Enhancing selectivity and efficiency in the electrochemical synthesis of adiponitrile》 in relation to this compound, is published in Reaction Chemistry & Engineering. Let’s take a look at the latest research on this compound (cas:4553-62-2).

Adiponitrile is a large scale chem. intermediate used in the production of Nylon 6,6. It is primarily produced via two methods: the thermal hydrocyanation of butadiene and the electrochem. hydrodimerization of acrylonitrile. The thermochem. method is an energy intensive process that involves acutely toxic reactants such as hydrogen cyanide. On the other hand, the electrosynthesis of adiponitrile is a green chem. process that uses water-based electrolytes and can be directly coupled with renewable electricity sources such as wind or sunlight. Although this process is the largest organic electrochem. process in industry, it still faces many challenges owing to its low energy conversion efficiency and selectivity. Using a systematic approach, this study provides insights into mass transport and kinetic factors that influence the reaction performance, and demonstrates that by careful control of the composition of the electrolyte, concentration of reactants, operating current densities, and temperature, selectivities as high as 83% can be achieved. Our results provide electrochem. engineering guidelines to significantly improve the efficiency of the electrochem. production of adiponitrile and open up opportunities to the direct implementation of renewable-energy sources in chem. manufacturing

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 Insight into polyacrylonitrile molecular structure from calculated vibrational frequencies and infrared intensities of model oligomers, the main research direction is polyacrylonitrile mol vibration model oligomer; IR intensity polyacrylonitrile mol vibration.Application In Synthesis of 2-Methylglutaronitrile.

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.
