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. SDS of cas: 31643-49-9.
Wang, Ting;Dayo, Abdul Qadeer;Wang, Zi-long;Lu, Hui-min;Shi, Cheng-yu;Pan, Zhong-cheng;Wang, Jun;Zhou, Heng;Liu, Wen-bin research published 《 Novel self-promoted phthalonitrile monomer with siloxane segments: synthesis, curing kinetics, and thermal properties》, the research content is summarized as follows. A new kind of autocatalytic phthalonitrile monomer (PN) containing siloxane segments and secondary amino groups (TSOP) was synthesized from bisphenol compound and 4-nitrophthalonitrile using K2CO3 as a catalyst. Bisphenol was a reducing agent with a Schiff base containing secondary amine groups produced by the condensation reaction of 1,3-bis(3-amino-propyl)-1,1,3,3-tetra-Me disiloxane and vanillin. The curing behaviors, kinetics, and thermal and thermomech. characteristics of the TSOP monomer and its polymer (poly(TSOP)) were analyzed by torque rheometry, differential scanning calorimetry (DSC), Fourier transformation IR spectroscopy (FTIR), thermogravity anal. (TGA), and dynamic thermal mech. anal. (DMA), resp. The non-isothermal curing kinetics results indicated that the cyano addition polymerization of the TSOP monomer was a self-catalytic reaction. The active hydrogen atoms from the secondary amino groups in the TSOP monomer could accelerate the crosslinking polymerization reaction of cyano groups, producing a decline in the curing temperature and a rise in the curing rate. Meanwhile, the TSOP monomer had a low melting temperature (77°C) and a wide process window (110°C) due to the introduction of flexible siloxane segments. The poly(TSOP) having phthalocyanine and a triazine ring exhibited a higher glass transition temperature (Tg) of 348°C and good thermal stability.
SDS of cas: 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., 31643-49-9.
