What is the preparation method of 4-iodo-1, 2-benzenedicarboxylic Acid?

The preparation method of 4-iodo-1,2-benzenedicarboxylic acid (4-iodo-1,2-benzenedicarboxylic Acid) is as follows:
can be started from phthalic anhydride. Phthalic anhydride is first halogenated to introduce iodine atoms. In a suitable reaction vessel, phthalic anhydride is placed in a specific solvent, such as glacial acetic acid, etc. This solvent can not only dissolve the reactants, but also has no adverse effect on the reaction process. Subsequently, an iodizing agent is added, such as iodine elemental substance in combination with an appropriate oxidizing agent, such as hydrogen peroxide or concentrated sulfuric acid in combination with iodine. The action of the oxidizing agent is to activate iodine and promote its substitution reaction with phthalic anhydride. The reaction process requires strict temperature control, usually maintained in a moderate range, such as 50-80 ° C. If the temperature is too low, the reaction rate is slow and time-consuming; if the temperature is too high, it is easy to initiate side reactions and cause impure products.
After a period of reaction, follow the reaction process with suitable monitoring means, such as thin layer chromatography (TLC), and stop the reaction when the reaction reaches the desired level, that is, most of the phthalic anhydride is converted into the target product. After that, the reaction mixture is treated. The reaction liquid is first cooled to allow some solids to precipitate, and then the solids are collected by filtration. The resulting solids still contain impurities and need to be further purified by recrystallization. Select a suitable recrystallization solvent, such as ethanol-water mixed solvent, according to the principle of similar miscibility, the target product is dissolved in the hot solvent, while the impurities remain in the insoluble matter. After cooling, the pure 4-iodine-1,2-phthalic acid is precipitated in a crystalline form, filtered again and dried to obtain a relatively pure product.
Another way can be prepared by carboxylation of the corresponding halogenated aromatic hydrocarbons. 4-iodo-o-xylene is used as the starting material, and in the presence of a suitable catalyst, such as palladium catalyst, it reacts with carbon monoxide and water or alcohols under specific pressure and temperature conditions. The pressure of the reaction system is maintained at a certain value, such as 2-5 MPa, and the temperature is about 100-150 ° C. This reaction needs to be carried out in an inert gas protective atmosphere to prevent catalyst poisoning and reactants from being oxidized. After the reaction is completed, 4-iodine-1,2-phthalic acid can also be obtained through a series of operations such as separation and purification. The specific separation and purification steps include extraction, distillation, recrystallization, etc., and are reasonably selected and combined according to the actual reaction conditions and impurity characteristics to obtain high-purity target products.

4-Iodine-1,2-phthalic acid, this product is in the market, what is the price? I tried to ask for it in "Tiangong Kaiwu", but I didn't get it. Now as far as I know, I have made a little statement about it.
This compound is used in various fields of chemical industry and has a wide range of uses. The change in its price depends on many ends. First, the price of raw materials is necessary. If the price of raw materials such as iodine and phthalic acid is high, the price of 4-iodine-1,2-phthalic acid is also high. The price of raw materials is expensive, which will lead to a significant increase in production costs. In order to protect their profits, merchants must raise their prices.
The second time, the simplicity of the craftsmanship is also relevant. If the method of preparation requires delicate techniques, harsh conditions, and labor and time, the price will be high. Fine and complex craftsmanship cannot be achieved without high cost, how can its price not rise?
Furthermore, the supply and demand of the city is the cardinal of the price. If there are many seekers, but there are few suppliers, the price will tend to rise; conversely, if the supply exceeds the demand, the price will fall. The market changes, supply and demand are impermanent, and prices fluctuate accordingly.
In today's market, 4-iodine-1,2-phthalic acid has different prices depending on the grade. Excellent grade, high purity, less impurities, used in high-end chemical industry, scientific research field, its price per gram or tens of yuan or even hundreds of yuan. Ordinary, slightly less pure, mostly used in general industry, per gram or a few to more than ten yuan.
However, this is only a rough estimate, the market situation changes, if you want to know the exact price, you should consult the chemical raw material supplier, reagent supplier, or visit the chemical product trading platform to get the real-time price.

4-Iodo-1, what are the storage conditions for 2-benzenedicarboxylic Acid?

4-Iodine-1,2-phthalic acid, which is also a chemical substance. Its storage conditions are quite important, related to the stability and quality of the substance.
When storing, it should first be placed in a cool place. Because the temperature is too high, or the substance may undergo a chemical reaction, affecting its chemical properties. If it is hot in summer, if it is not placed in a cool place, it is feared that its ingredients will mutate.
Furthermore, it is necessary to keep a dry environment. Humid air can easily damp the substance, or cause adverse reactions such as hydrolysis. For example, during the rainy season in the south, the air humidity is high, so it is necessary to take moisture-proof measures, and desiccant can be placed in a storage place.
And should be stored in a well-ventilated place. Good ventilation can avoid the accumulation of harmful gases. If the substance evaporates a little gas, ventilation can make it escape, so as not to cause danger due to accumulation, and it is also beneficial to maintain its chemical stability.
Also, keep away from fire sources and oxidants. 4-Iodine-1,2-phthalic acid is exposed to fire or contact with oxidants, or there is a risk of combustion or explosion. If the oxidant is highly oxidizing, contact with it or cause a violent reaction.
Storage containers should also be noted. Corrosion-resistant materials should be used to prevent the container from reacting with substances, damaging the container and affecting the quality of the substance.
In general, when storing 4-iodine-1,2-phthalic acid, keep cool, dry, and ventilated, and choose a suitable container away from fire sources and oxidants, so as to ensure the stability and safety of the substance during storage.
