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. Electric Literature of 31643-49-9.
Jiang, Hongyu;Zhang, Hong;Wen, Yaqing;Tan, Liyun;Fang, Xingzhong;Chen, Guofei research published ã?Synthesis and comparative study on copolyetherimides from mixed isopropylidenebis(1,4-phenylene-oxy) bis(phthalic anhydride)sã? the research content is summarized as follows. Mixed isopropylidenebis(1,4-phenylene-oxy) bis(phthalic anhydride)s with different ratios (Mixed-BPADA 1-3) were synthesized successfully via aromatic nucleophilic substitution from nitrophthalonitrile and bisphenol A. The corresponding copolyetherimides (CoPEIs) were prepared with two representative aromatic diamines (4,4′-oxydianiline (4,4′-ODA) and m-phenylenediamine (m-PDA)) via two-step procedure and chem. imidization. CoPEIs showed Tgs from 222 to 256°C and Td5%s from 486 to 505°C in argon, good mech. properties (tensile moduli of 2.5-2.9 GPa, tensile strengths of 69-96 MPa, and elongations at break of 3.3-6.3%), and good solubility With the introduction of 3-substituted phthalimide unit, CoPEIs displayed higher Tg values, lower elongations, better solubility and larger d-spacings. The rheol. properties of thermoplastic polyimide resins based on the mixed-BPADA were investigated. CoPEI-b series displayed good melt processibility, and the CoPEI-3b derived from mixed-BPADA 3 and m-PDA had the lowest melt viscosity among the copolymers. Compared to isomeric PEIs derived from BPADA isomers, CoPEIs displayed lower melt viscosities, indicating that the melt processibility had been greatly improved.
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., Electric Literature of 31643-49-9
