3,4-Dicyano Aniline - Reference Information
| LogP | 0.72 at 25℃ |
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Use | 4-aminophthalonitrile is a typical representative of phthalonitrile, at present, it is usually prepared by catalytic hydrogenation under high pressure. Phthalonitrile is an important intermediate for the preparation of phthalocyanine, so it is very important to prepare amino substituted phthalonitrile. |
| preparation | 4-nitrophthalonitrile was dissolved in 50ml of methanol and 20ml of hydrochloric acid, and iron powder (6g,107mmol); After 5 hours of reflux, the crude product was distilled off under reduced pressure to obtain a crude product, which was separated by column chromatography (eluent: dichloromethane/ethyl acetate, 1/1) to obtain a white solid, yield 62%. |
