2% 2C4% methyl 2C5-tribromobenzoate is an organic compound with the following chemical properties:
First, acidic. This molecule contains a carboxyl group, which can weakly ionize hydrogen ions in water and is acidic. In case of strong bases such as sodium hydroxide, a neutralization reaction will occur to form corresponding carboxylate and water, which is a typical property of organic acids.
Second, substitution reaction. The hydrogen atom on the benzene ring is affected by the carboxyl group and the bromine atom, and has a certain activity. Under specific conditions, if the catalyst and the reaction temperature are suitable, an electrophilic substitution reaction can occur. For example, in the reaction with bromine elemental matter catalyzed by iron bromide, the unsubstituted position on the benzene ring will introduce bromine atoms to form polybrominated products.

To make 2,4,5-trifluorobenzoic anhydride, you can follow the following ancient method.
First take an appropriate amount of 2,4,5-trifluorobenzoic acid and place it in a clean kettle. For the kettle, it should be made of pottery or copper, which can withstand high temperature and does not phase with the material. Under the kettle, slow down the burning with charcoal fire, so that the benzoic acid gradually melts and turns into a fluid.
Then, add an appropriate amount of dehydrating agent, such as phosphorus pentoxide. For phosphorus pentoxide, it is dry and can be melted by water. Put it in the kettle, mix it with the liquid benzoic acid, and stir to make it well. The mixing equipment should be wood or bamboo, and do not use iron, lest the iron equipment and the material will be phased and mixed.
When stirring, the fire is getting more and more fierce, causing the temperature in the kettle to rise gradually. Careful attention should be paid to the change of temperature, not too high or too low. If the temperature is too high, the material may decompose; if the temperature is too low, the reaction will be slow and difficult. When the flue gas in the kettle gradually rises, and there are bubbles gurgling out, this is the appearance of the reaction being in full swing.
After a while, the reaction gradually finishes. When the material in the kettle is slightly cold, use a condenser to collect the steam escaping from it. The steam cools and condenses, that is, 2,4,5-trifluorobenzoic anhydride. The product received may be purified by recrystallization. Take an appropriate amount of solvent, such as ethanol or ether, dissolve the product into it, heat it to dissolve, and then cool it, so that the product slowly crystallizes and comes out, filtered to obtain pure 2,4,5-trifluorobenzoic anhydride.
The whole process requires strict compliance with laws, paying attention to the heat, the amount of materials and the time of reaction, so as to obtain good results and obtain the required 2,4,5-trifluorobenzoic anhydride.
