3,5-DINITROPHENOL - References
| Use | for organic synthesis. As an acid-base indicator, its color change range is pH 4.0 (colorless)-5.4 (yellow) |
| production method | is obtained by nitration of M-nitrophenol. M-nitrophenol was mixed with nitric acid having a relative density of 1.3, and the reaction was started with slight heating, and a large amount of brown nitrogen oxide gas was emitted. The reaction solution started to boil vigorously. After cooling, the liquid is divided into two layers, and the lower layer is washed with cold water to obtain a viscous red oil, which is distilled with steam. After cooling, an almost colorless needle-like crystal is obtained, which is 3 after drying, 5-dinitrophenol finished product. |
