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. Recommanded Product: 4-Nitrophthalonitrile.
Orlova, A. M.;Tsegelskaya, A. Yu.;Kolesnikov, T. I.;Abramov, I. G.;Kuznetsov, A. A. research published 《 Novel polyetherimides based on 5-methyl-1,3-phenylene-bis-4-oxyphthalic acid dianhydride: synthesis and physicochemical properties》, the research content is summarized as follows. A novel monomer for the synthesis of polyimides, 5-methyl-1,3-phenylene-bis-4-oxyphthalic acid dianhydride was developed. The synthesis was carried out in three stages: the reaction of nucleophilic nitro substitution of 4-nitrophthalonitrile with 5-methylresorcinol (orcinol) potassium salt and subsequent hydrolysis of the nitrile groups have afforded 5-methyl-1,3-phenylene-bis-4-oxyphthalic acid, dehydration of which has given the corresponding dianhydride. A series of new thermoplastic high mol. weight polyetherimides based on 5-methyl-1,3-phenylene-bis-4-oxyphthalic acid dianhydride and several aromatic diamines of various structures were synthesized by the method of one-stage catalytic polycondensation in a benzoic acid melt. Inherent viscosity and weight-average mol. mass of the polyetherimides have been of 0.28-1.20 dL/g and (33-114) × 103, resp. The polyetherimides have been soluble in chloroform, THF, DMF, dimethylacetamide, N-methylpyrrolidone, and DMSO and have revealed film-forming properties. According to the DSC and wide-angle X-ray scattering data, the polyetherimides have been found completely amorphous, the glass transition temperature being in the 185-307° range.
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., Recommanded Product: 4-Nitrophthalonitrile
