What is 3-Chloro-4-Nitrobenzotrifluoride production method?
The preparation method of 3-chloro-4-nitrotrifluorotoluene, the ancient Fangjia followed the following paths.
First, with trifluorotoluene as the base, the technique of nitrification is first performed. The trifluorotoluene is placed in a specific reactor, and an appropriate amount of mixed acid, such as the mixture of nitric acid and sulfuric acid, is added. The temperature is controlled within a certain range, usually at a moderate low temperature, about 0 ° C to 10 ° C. The mixed acid is slowly added dropwise. This process requires careful observation of the reaction situation to prevent excessive reaction. After mixing the acid dropwise, continue to stir at this temperature for several hours to make the nitrification reaction complete. After this step, 4-nitrotrifluorotoluene can be obtained. Then, 4-nitrotrifluorotoluene is chlorinated again. An appropriate amount of chlorination reagent, such as chlorine or thionyl chloride, is added to the reaction system, and a specific catalyst, such as iron powder or ferric chloride, is catalyzed. The reaction temperature may be raised to a higher range, about 50 ° C to 100 ° C, and the chlorination reaction is continuously stirred, so that the chlorination reaction is fully carried out, and the final product is 3-chloro-4-nitrotrifluorotoluene.
Second, 3-chlorotrifluorotoluene is also used as the starting material. 3-chlorotrifluorotoluene is first interacted with the nitrate, but in this process, the controlled reaction conditions are slightly different from the former. The concentration of nitrate, reaction temperature, reaction time, etc. all need to be fine-tuned. Generally speaking, the reaction temperature may be slightly higher than that of trifluorotoluene, about 10 ° C to 30 ° C, and a specific reaction solvent, such as dichloromethane or nitromethane, is used to promote the reaction. After nitration, the target product 3-chloro-4-nitrotrifluorotoluene can be obtained.
These two are common preparation methods. However, to obtain pure 3-chloro-4-nitrotrifluorotoluene, subsequent refining methods such as extraction, distillation, and recrystallization are required to remove impurities and obtain high-purity products.
