Nitriles are found in many useful compounds. Nitrile rubber is also widely used as automotive and other seals since it is resistant to fuels and oils. Organic compounds containing multiple nitrile groups are known as cyanocarbons. 31643-49-9, formula is C8H3N3O2, Name is 4-Nitrophthalonitrile. Nitriles are found in many useful compounds. One of the most common occurrences of nitriles is in Nitrile rubber. Name: 4-Nitrophthalonitrile.
Wu, Minjie;Gu, Yuxuan;Hao, Diyi;Chen, Xinggang;Yu, Xiaoyan;Zhang, Qingxin research published 《 Fluorinated Phthalonitrile Resin with Excellent Thermal Stability and Low Dielectric Constant for High-Frequency Electronic Packaging》, the research content is summarized as follows. Phthalonitrile (PN) resin promising material for preparing high-speed and high-frequency electronic packaging because of its unique high temperature resistance and excellent insulation performance. A fluorinated PN oligomer (4,4′-bis (p-perfluoro-phenol-(bis(p-phenol)perfluoropropane-2,2-diyl)-p-oxy-diphthalonitrile) (PFDP)) containing trifluoromethyl and decafluorobiphenyl groups are designed, synthesized, and characterized. The oligomer is blended with 4-(aminophenoxy)phthalonitrile (APPH), and then cured into polymers under the temperature-programmed process. The reactive blend has good processability, and structures of isoindole, triazine ring, and phthalocyanine ring are found in the curing reactions. The fluorinated PN (P-380) shows outstanding thermal stability and mech. properties (5% thermal degradation temperature: 518°C (N2); 516 (Air), THeat-resistance index: 268°C, activation energy of thermal decomposition: 334.89 kJ mol-1, glass transition temperature (Tg) > 400°C). Meanwhile, the fluorinated PN simultaneously exhibited a superior low dielec. constant (Dk, 2.21) and dielec. loss (Df, 0.01) at 10 GHz. Moreover, the water absorption of the resin is as low as 0.74%, which meets the requirement of dielec. materials. These results would strongly suggest such PFDP PN resin as excellent packaging materials in those high-tech applications such as aerospace and communication electronic devices.
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
