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.
Wang, Ting;Shi, Cheng-yu;Qadeer Dayo, Abdul;Guo, Zhi-yi;Wang, Jun;Wang, Yanhui;Gorar, Athar Ali Khan;Qiu, Jian;Liu, Wen-bin research published 《 Synthesis and properties of novel self-catalytic phthalonitrile monomers with aliphatic chain and their copolymerization with multi-functional fluorene-based benzoxazine monomers》, the research content is summarized as follows. A novel series of self-catalytic phthalonitrile monomers with aliphatic segments (BPAA) were synthesized via nitro nucleophilic substitution reaction of bisphenol compound and 4-nitrophthalonitrile. Bisphenol compound was reductant with secondary amine groups of Schiff base derived from the reaction of vanillin and one of the aliphatic diamine such as 1,2-ethylenediamine, 1,3-propane diamine, and 1,6-hexamethylenediamine. The curing reaction of BPAA monomers can be carried out without any catalyst. BPAA monomers showed excellent processing properties. Moreover, BPAA polymers (poly(BAPP)) showed superior thermal stabilities and higher glass-transition temperatures (Tg) (302-317°C). The 5% thermal decomposition temperatures (T5) of poly(BAPP) and char yield (Yc) at 800°C under nitrogen atm. were 352.5-410.5°C and 61.3-66.8%, resp. To further improve the thermal stability of poly(BAPP), BPAA monomers were modified by multi-functional fluorene-based benzoxazine monomers (MFFB) due to their excellent reaction activities. The results showed that BAPP/MFFB systems had high reaction activities and good processing behaviors. The similar thermal stabilities between BAPP and MFFB can give stable and excellent thermal stability (T5 ≥ 378°C) to the poly(BAPP/MFFB) systems.
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
