Industrially, the main methods for producing nitriles are ammoxidation and hydrocyanation. 31643-49-9, formula is C8H3N3O2, Name is 4-Nitrophthalonitrile. Both routes are green in the sense that they do not generate stoichiometric amounts of salts. Category: nitriles-buliding-blocks.
Yang, Wenjie;Qi, Jiayue;Tan, Wei;Zhu, Zhengzhu;He, Xian;Zeng, Ke;Hu, Jianghuai;Yang, Gang research published 《 Study on aromatic nitrile-based resins containing both phthalonitrile and dicyanoimidazole groups》, the research content is summarized as follows. In order to prepare aromatic nitrile-based resins with improved curing reactivity, thermal and thermomech. properties, and to clarify the difference in curing activity between dicyanoimidazole and phthalonitrile groups, a novel class of autocatalytic aromatic nitrile-based resins named PNDCI which contains both dicyanoimidazole (DCI) and phthalonitrile (PN) groups were designed and synthesized. A method for evaluating the reactivity of nitrile groups using the absorption wavenumber of FTIR was proposed. PNDCI monomers have demonstrated higher activity for self-promoted curing reactions than benzimidazole-containing phthalonitrile monomers (BIPN). The introduction of DCI can change the curing pathway of PN and inhibit the formation of phthalocyanine ring which is an important cured product of PN resins. The data of TGA, DMA, etc. revealed that the cured products of PNDCIs showed outstanding thermal stability, long-term thermo-oxidative stability at high temperatures (425°C) and thermal mech. properties, which is favorable for the preparation of high temperature resistant 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., Category: nitriles-buliding-blocks
