Inorganic compounds containing the −C≡N group are not called nitriles, but cyanides instead.31643-49-9, formula is C8H3N3O2, Name is 4-Nitrophthalonitrile. Though both nitriles and cyanides can be derived from cyanide salts, most nitriles are not nearly as toxic. Application of C8H3N3O2.
He, Liang;Tong, Lifen;Xia, Yunqing;Lin, Guo;Wang, Ting;Zhang, Wanru;Liu, Yingfa;Liu, Xiaobo research published 《 Advanced composites based on end-capped polyarylene ether nitrile/bisphthalonitrile with controllable thermal curing reaction》, the research content is summarized as follows. A novel polymer was prepared through the combination of phthalonitrile end-capped polyarylene ether nitrile (PEN-Ph) and bisphthalonitrile (BPh), applying post-solid phase chem. reaction technol. BPh monomer was firstly pre-polymerized to form BPh prepolymer and then followed by crosslinking reaction with PEN-Ph matrix resin to obtain PEN-Ph/BPh composites. The generated crosslinking structures were confirmed by FTIR and UV including phthalocyanine, triazine, and isoindoline rings. Besides, the effect of BPh pre-polymerization time on the performance of PEN-Ph/BPh composite materials was studied. Tensile strength and modulus highest values of composites exceeded 98.9 MPa and 2.17 GPa resp. as BPh pre-polymerization time reached 30 min, improved by 55.6% and 36.9% in comparison with unpolymerized one. Besides, PEN-Ph/BPh composite films exhibited superior thermal properties (Tg: 278-330°C, T5% (decomposition temperature of 5 wt%)>500°C) and maintained excellent dielec. stability over 300°C, leading to use for electronic fields at elevated temperature
Application 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.
