The synthesis method of 2-methyl-4-iodophenol, although the ancient book "Tiangong Kaiwu" does not contain the specific synthesis method of this compound, it can be deduced by referring to the principles and methods of organic synthetic chemistry at present.
First, 2-methylphenol is used as the starting material, and the iodine atom at the 4th position is to be introduced. The electrophilic substitution reaction characteristics of phenolic compounds can be exploited. The phenolic hydroxyl group is a strong donator group, which increases the electron cloud density of the phenyl ring and the para-position, which is conducive to the attack of electrophilic reagents.
The combination of iodine element ($I_2 $) and an appropriate oxidizing agent can be selected. If hydrogen peroxide ($H_2O_2 $) is used as an oxidizing agent, under acidic conditions, hydrogen peroxide can oxidize iodine ions to iodine positive ions ($I ^ + $), which is a strong electrophilic reagent and can attack the 4 position of the 2-methylphenol phenyl ring. Electrophilic substitution reaction occurs to generate 2-methyl-4-iodophenol. The reaction steps are as follows: in the reaction vessel, add 2-methylphenol, an appropriate amount of iodine elemental substance and solvent, such as glacial acetic acid, under low temperature stirring, slowly add hydrogen peroxide solution dropwise, control the reaction temperature and time, and after the reaction is completed, the target product is obtained through separation and purification.
Second, it can also be started from 4-iodoaniline. First, through the diazotization reaction, the amino group is converted into a diazonium salt, such as reacting with sodium nitrite in the presence of hydrochloric acid to form a diazonium salt. Then through the Sandmeier reaction or similar reactions, the cyanyl group is substituted for the diazonium group, and then the cyanyl group is hydrolyzed to the carboxyl group. Then through the decarboxylation reaction, the methyl group is introduced in combination with the methylation step to finally synthesize 2-methyl-4-iodophenol. This route is a bit complicated, but it is also a feasible method. During the synthesis process, the control of the reaction conditions at each step, the trade-off of the amount of reagents, and the separation and purification of the product are all key, which

2-Methyl-4-iodophenol is an organic compound. When storing and transporting, many matters need to be paid attention to.
First talk about storage. This compound is quite sensitive to light and heat, and should be stored in a cool and dark place. Due to light and high temperature, it can decompose and deteriorate, damaging its quality. The temperature of the warehouse should be strictly controlled, and it should not exceed 30 ° C, and it should be kept dry to avoid moisture, because moisture may also cause reactions and affect purity.
Furthermore, this compound has certain toxicity and irritation. When storing, it must be separated from oxidants, acids, bases, etc., and cannot be mixed. Because it encounters with these substances, or reacts violently, it causes safety hazards. At the same time, the warehouse should set up obvious warning signs to remind people entering and leaving to pay attention to protection.
As for transportation, it is necessary to ensure that the packaging is intact. Packaging materials should have good sealing and corrosion resistance to prevent leakage. During transportation, vehicles should also run smoothly to avoid bumps and vibrations and prevent packaging from breaking.
Transportation personnel should also be professionally trained to be familiar with the dangerous characteristics of 2-methyl-4-iodophenol and emergency treatment methods. In case of leakage during transportation, emergency measures should be taken immediately to evacuate people, isolate contaminated areas, and properly dispose of leaks to ensure the safety of personnel and the environment from pollution.
In summary, the storage and transportation of 2-methyl-4-iodophenol are subject to strict requirements in terms of temperature, humidity, light, packaging and personnel operation, so as to ensure its safety and quality.
