Nitriles used to be known as cyanides; the smallest organic nitrile is ethanenitrile, CH3CN, (old name: methyl cyanide or acetonitrile – and sometimes now called ethanonitrile). 31643-49-9, formula is C8H3N3O2, Name is 4-Nitrophthalonitrile. Nitriles are found in many useful compounds, including methyl cyanoacrylate, used in super glue, and nitrile rubber, a nitrile-containing polymer used in latex-free laboratory and medical gloves. Name: 4-Nitrophthalonitrile.
Hu, Jianghuai;Xie, Huanxin;Zhu, Zhengzhu;Yang, Wenjie;Tan, Wei;Zeng, Ke;Yang, Gang research published 《 Reducing the melting point and curing temperature of aromatic cyano-based resins simultaneously through a Bronsted acid-base synergistic strategy》, the research content is summarized as follows. High m.ps. (Mp) and high curing temperatures are two key processing problems that limit the application of aromatic cyano-based (AC) resins. A Bronsted acid-base synergistic strategy based on an acid-base eutectic and mechanisms for nucleophilic addition and ionization equilibrium are proposed to reduce the Mp and curing temperature of AC resins. Blends of 4,5-dicyanoimidazole (DCI, Bronsted acid) and amine-containing phthalonitriles (4 or 2 or 3)-aminophenoxy phthalonitrile, APNs, Bronsted bases were selected as model acid-base systems to study the synergistic behaviors in processing. The results show that the Mp and the peak exothermic temperature (Trp) of APN-DCI blends can be reduced by more than 31°C and 85°C compared with their intrinsic components, resp. DSC and XRD show that the decrease in the Mp of the blends is induced by the formation of eutectics. A pos. relationship between pKa and the curing reactivity is confirmed by theory and exptl. methods. The cured products show outstanding thermal and mech. properties compared with reported AC resins. This research provides a new convenient route for regulating the curing behavior of AC resins and will significantly promote the development of high-performance AC resins.
31643-49-9, 4-Nitrophthalonitrile, also known as 4-Nitrophthalonitrile, is a useful research compound. Its molecular formula is C8H3N3O2 and its molecular weight is 173.13 g/mol. The purity is usually > 95%.
4-Nitrophthalonitrile is a chemical substance that can be synthesized by the reaction of sodium carbonate with 3,4,5-trimethoxybenzyl alcohol. It can also be prepared using nitro phenol and sodium hydroxide. 4-Nitrophthalonitrile has been shown to have high photochemical activity in the presence of light. The frequency shift of its infrared spectrum is indicative of a nucleophilic addition reaction mechanism. 4-Nitrophthalonitrile has been used as an intermediate for producing other chemicals, such as herbicides and pharmaceuticals., Name: 4-Nitrophthalonitrile
