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. Application of C8H3N3O2.
He, Liang;Tong, Lifen;Bai, Zhongxiang;Lin, Guo;Xia, Yunqing;Liu, Xiaobo research published 《 Investigation of the controllable thermal curing reaction for ultrahigh Tg polyarylene ether nitrile compositions》, the research content is summarized as follows. High-performance polymer plays critical roles in 5G communication and electronic applications. Hence, special engineering plastic polyarylene ether nitrile (PEN) suitable for use in a harsh environment (Tg > 400°C,T5% > 500°C, and tensile strength 100 MPa) has been developed. Bisphthalonitrile (BPh) units form a flexible bridge between the nitrile of PEN. In the preparation, DDS acts as a catalyst and ZnCl2 functions as both a catalyst and a reinforcing phase, to enhance the degree of crosslinking and mech. properties of the resulting compositions Therefore, the structure of a linear polymer is converted into a 3D network, resulting in greatly enhanced performance. The mode of action for DDS/ZnCl2 and the transformation of nitrile groups has been described. These insights provide an understanding of the impact of crosslinking factors in structure formation and supply a feasible design strategy for the preparation of high-performance polymer films.
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., Application of C8H3N3O2
