2-Fluoro-3-methylnitrobenzene, 2-Fluoro-1-methyl-3-nitrobenzene - Reference Information
| LogP | 1.423 |
| use | 2-fluoro-3-nitrotoluene is one of the fluorine-containing aromatic compounds. Compared with fluorine-containing aromatic compounds, it has less dosage, low toxicity, high efficacy, strong metabolic ability and other excellent properties in medicine, pesticides and other fields, and has a wide range of uses. |
| production method | (1) nitrification: the raw material o-fluorotoluene is added to the reaction kettle, the temperature is reduced to 20 degrees Celsius in a water bath under normal pressure, mixed acid prepared by nitric acid and sulfuric acid is added dropwise under stirring, and then reacted at a temperature of 20-35 degrees Celsius to prepare a mixture of 2-fluoro -5-nitrotoluene and 2-fluoro -3-nitrotoluene;(2) Separation: The above mixture is washed with water and alkali to neutral, rectified under high-efficiency vacuum distillation, and refined to produce 2-fluoro-3-nitrotoluene finished product. |
