What are the preparation methods of 2-iodo-m-toluic Acid?

There are many methods for preparing 2-iodo-m-toluic acid. The details are as follows:
First, it can be obtained from m-toluic acid through iodization reaction. First, take an appropriate amount of m-toluic acid and place it in a suitable reaction vessel. M-toluic acid is the starting material of this reaction, and its structure contains benzene ring, methyl group and carboxyl group. Then, add an appropriate amount of iodizing reagent, such as iodine elemental substance and appropriate oxidant combination. Common oxidants include hydrogen peroxide, concentrated sulfuric acid, etc. The function of the iodizing reagent is to provide iodine atoms, so that the iodization substitution reaction occurs on the benzene ring. The reaction needs to be carried out under appropriate reaction conditions, and temperature control is crucial. Generally, it can be carried out under mild heating conditions, about 50-80 ° C. This temperature range is conducive to the progress of the reaction and can avoid overreaction. At the same time, the pH of the reaction system should also be paid attention to, and a certain pH value can be maintained by adding an appropriate amount of buffer. The reaction time depends on the reaction process, which generally takes several hours to ten hours. During this period, the reaction process can be monitored by means of thin-layer chromatography (TLC). When the raw material m-toluic acid is completely consumed, the reaction end point is reached. At this time, after a series of post-processing steps, such as after the reaction liquid is cooled, it is extracted with an appropriate organic solvent. The extraction liquid is washed, dried, concentrated, etc. The crude product can be obtained, and then further purified by recrystallization and other methods, that is, 2-iodoisotoluic acid.
Second, it can also be prepared by using m-methylbenzoate as raw material. First, m-methylbenzoate is reacted with an iodizing reagent under specific conditions. The structure of m-methylbenzoate is slightly different from that of m-toluic acid, and its carboxyl group exists in the form of an ester group. The selection of iodizing reagents and the control of reaction conditions for this reaction are similar to the above-mentioned reaction using m-toluic acid as raw material. After the iodization reaction is completed, the ester group hydrolysis When hydrolyzing, acidic or alkaline conditions can be selected. If alkaline hydrolysis is used, an aqueous solution of a base such as sodium hydroxide is often mixed with the reaction product, heated and refluxed for a period of time to convert the ester group into a carboxyl group. After the reaction is completed, after acidification, extraction, purification and other steps, 2-iodo-m-toluic acid can finally be obtained.
Third, it can be prepared by the Grignard reagent method. First, the Grignard reagent is prepared with isobromotoluene. The isobromotoluene reacts with magnesium shavings in an inert solvent such as anhydrous ether to form the Grignard reagent with isotoluene magnesium bromide. This Grignard reagent has active chemical properties and can react with carbon dioxide to introduce carboxyl groups. Then, it is acidified to convert the generated car Finally, the iodization reaction is carried out, and the iodization method as described above is used to obtain 2-iodotoluic acid. During the whole process, the control of reaction conditions and post-processing operations of each step need to be carefully controlled to obtain high-purity products.

What should be paid attention to when storing and transporting 2-iodo-m-toluic Acid?

2 - Iodine-m-toluic acid is an organic compound. When storing and transporting, be sure to pay attention to the following points:
First, the storage place should be cool, dry and well ventilated. This compound is easy to decompose when heated, and high humidity may cause the risk of moisture degradation, and poor ventilation will cause the accumulation of harmful gases, endangering safety. Therefore, it is necessary to choose one that is far away from heat sources and water sources, and has smooth air circulation.
Second, it should be stored separately from oxidants and alkalis, and should not be mixed. 2 - Iodine-m-toluic acid has a certain chemical activity. Contact with oxidants or trigger violent chemical reactions, even causing combustion and explosion; when it encounters alkalis, it may also react, which may damage the quality of the product.
Third, the storage container must be tightly sealed. This is to prevent it from volatilizing or reacting with components in the air. Sealed containers made of glass, plastic and other materials can be used. However, the compatibility of 2-iodine-m-toluene acid with it needs to be considered to ensure that corrosion does not occur.
Fourth, when transporting, make sure that the container does not leak, collapse, fall, or damage. It needs to be lightly loaded and unloaded to avoid severe vibrations and collisions, otherwise the container will break and cause material leakage, or cause safety accidents.
Fifth, the transportation vehicle should be equipped with the corresponding variety and quantity of fire fighting equipment and leakage emergency treatment equipment. In the event of a leak or fire and other accidents, timely response measures can be taken to reduce hazards. During transportation, it is also necessary to protect against sun exposure, rain exposure, and high temperature.
In short, during the storage and transportation of 2-iodine-m-toluene acid, there are strict requirements on the environment, containers, operation, and emergency preparedness, so as to ensure its quality and the safety of transportation and storage.
