What is the synthesis method of 2,5-dichloroiodobenzene?
2% 2C5-difluorobenzoic acid is an intermediate in organic synthesis and is widely used in the fields of medicine, pesticides, etc. Its synthesis methods are diverse. Although the synthesis method is not directly recorded in "Tiangong Kaiji", according to the chemical principle and the idea of preparing similar substances in ancient times, the following speculative methods can be tried.
If you want to make 2% 2C5-difluorobenzoic acid, you can start from benzoic acid. Although there are no modern advanced fluorination reagents in ancient times, fluorine-containing natural minerals can be used. For example, fluorite (CaF _ 2), fluorite is first heated with concentrated sulfuric acid to obtain hydrogen fluoride gas (HF). This reaction principle is: CaF _ 2 + H _ 2O SO _ (concentrated) = Delta = CaSO _ + 2HF ↑.
Next, benzoic acid is reacted with the obtained hydrogen fluoride under specific conditions. Benzoic acid can be placed in a special ceramic reactor and catalyzed at high temperature to promote fluorination. Although there are no modern high-efficiency catalysts in ancient times, some metal oxides or salts can be tried. For example, using mercury oxide (HgO) or mercury chloride (HgCl ²) as catalysts, in a high-temperature closed environment, benzoic acid reacts with hydrogen fluoride, which is expected to introduce fluorine atoms at the 2,5 position of the benzene ring to generate 2% 2C5-difluorobenzoic acid. The reaction is roughly as follows: C H O ² + 2HF → C H F O ² + 2H ² O (the reaction requires a specific catalyst and high temperature conditions).
In addition, natural aromatic compounds can also be considered as starting materials. For example, compounds containing benzene rings extracted from plants such as cinnamon and cloves, converted into benzoic acid analogues after appropriate treatment, and then the above fluorination reaction may also synthesize the target product. However, this process requires fine control of the reaction conditions at each step to improve the purity and yield of the product. Although ancient technical means are limited, with wisdom and practical exploration, a feasible synthesis path may be explored.

Second, avoid moisture. Moisture is often the enemy of many drugs, and 2% 2C5-dioxythiophene is not immune. Excessive ambient humidity may cause it to absorb moisture, causing deliquescence, mildew, etc. In severe cases, or biochemical reactions, causing it to lose its original properties. The storage place must be dry, and a desiccant can be placed in the storage place to absorb the surrounding moisture.
Third, it should be properly sealed. Excessive contact with air, 2% 2C5-dioxythiophene is easy to oxidize, resulting in quality degradation. It is essential to choose a well-sealed container, such as a glass bottle with a sealant plug, or a plastic container with good sealing performance. Be sure to seal it immediately after each use to prevent air from entering.
Fourth, keep away from fire sources and strong oxidants. 2% 2C5-dioxythiophene may be flammable to a certain extent, and in case of strong oxidants, it is easy to react violently, and there is even a risk of explosion. There should be no fire sources around the storage place, such as open flames, unextinguished cigarette butts; nor should it be co-located with strong oxidants, such as potassium permanganate, hydrogen peroxide, etc.
Fifth, follow the specified storage period. When the drug is effective, 2% 2C5-dioxythiophene also has a specified shelf life. Beyond this period, even if the storage conditions are appropriate, its quality is difficult to guarantee. Regular inspection, for those approaching or exceeding the shelf life, must not be reused, when properly disposed of in accordance with regulations.
