What is the production method of 2,4-dimethoxyfluorobenzene?
The preparation method of 2% 2C4-dimethoxy naphthalene is as follows:
In the past, to make this product, it was often necessary to use various medicinal materials and utensils in a subtle way. First take a suitable naphthalene substrate and place it in a clean kettle. The kettle needs to be carefully cleaned to avoid impurities.
Then, prepare the relevant reagents of dimethoxy group. The preparation of this reagent also needs to be careful, according to specific proportions and procedures. It is slowly injected into the kettle containing naphthalene substrate, and at the same time pay attention to the rate of injection, so as not to overstep the reaction.
When reacting, its temperature needs to be controlled. Use charcoal fire or warm water bath to maintain a specific temperature range in the kettle. If it is too low, the reaction will be slow, and if it is too high, it may cause clumps of side reactions. Keep this temperature, so that the substrate and the reagent slowly blend, and the chemical change will occur.
After the reaction is completed, the product is mixed in the kettle, and it needs to be separated and purified. Or use the method of distillation to separate the product from the impurities by the difference in the boiling points of different substances. Or use the method of extraction to extract the pure 2% 2C4-dimethoxynaphthalene with a suitable solvent.
Between operations, the craftsman must be attentive and careful, and follow the procedures step by step. A slight mistake may cause the product to be impure, or damage the utensils, and even endanger the human body. This is all the important thing to pay attention to when preparing 2% 2C4-dimethoxynaphthalene.
