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. Product Details of C8H3N3O2.
Alshahrani, Hassan;Dayo, Abdul Qadeer;Liu, Wen-bin research published 《 Development of chopped glass fiber composites with difunctional benzoxazine and bio-based phthalonitrile copolymer: A study of mechanical and thermomechanical properties》, the research content is summarized as follows. The randomly-oriented glass fibers (GF) reinforced composites with Bisphenol A-amine based benzoxazine (BA-a) and bio-based eugenol-based phthalonitrile (EPN) copolymer were developed by an isothermal compression molding technique. The silane coupling agent-treated GF (TGF) reinforced composites showed much better impact strength as compared to as-received GF reinforced composites. A rise of 95.2 MPa, 5.5GPa, 69.1 MPa, and 2.5GPa in flexural strength, flexural modulus, tensile strength, and Young’s modulus were observed, resp. The DMA results confirmed that the storage modulus (E’) and glass transition temperature (Tg) were gradually increased and the damping factor decreased as the TGF reinforcement was raised from 0 to 40 weight%. E’ and Tg values were 3.09 GPa and 27°C, resp., higher than the recorded values for the neat copolymer. The 40 weight% TGF reinforced poly(BA-a/EPN) composite showed the maximum thermal stability values of 475.4, 507.3°C, and 75.43% for T5, T10, and Yc, resp. The LOI values confirm that the TGF/copolymer composites have self-extinguishing properties.
Product Details of C8H3N3O2, 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., 31643-49-9.
