| Product description: Synonyms: 5-Nitroisophthalic acid CAS No.: 618-88-2 Molecular Formula: C8H3NO6 Molecular Weight: 209.1136 EINECS No.: 210-568-3 Structure: Chemical Properties: Boiling Point: 259-261 °C(lit.) Density(25°C): 1.6342 (rough estimate) Flash point: 120°C Appearance: White phyllodes Safety Info: WGK Germany ：3 Application: 2,6-dicyano-4-nitroaniline was obtained by cyanidation and ammoniation. It is an important intermediate of disperse dyes. In the first step, 5-nitro-m-phthalonitrile was synthesized by cyanidation with xylene as solvent and refluxing at 135-140 ℃ for 2-4h. The yield was over 91%. The second step is ammoniation reaction at 25-30 ℃ for 4h, and the yield is more than 80%. 5-nitroisophthalic acid is also an intermediate for the diagnosis of new panning. It is used as intermediate of medicine, pesticide, dye and pigment. Packing: 25kg composite paper bag lined with 1 layer of PE bag or 1 ton / ton bag |
