The synthesis method of 3-methyl-2-thiophene formaldehyde has been explored by many parties throughout the ages, and now it is listed below.
First, 3-methylthiophene is used as the starting material. First, it is combined with N-methylaniline under the action of phosphorus oxychloride and undergoes the Wilsmeer-Hack reaction. This reaction needs to be carried out at a suitable temperature and duration. During the reaction, the amount of phosphorus oxychloride and the reaction temperature are the key factors. If the temperature is too high, side reactions occur frequently; if the temperature is too low, the reaction is slow. After the reaction is completed, regular post-treatment, such as extraction, washing, drying, distillation and other steps, can obtain 3-methyl-2-thiophenylformaldehyde.
Second, use 2-bromo-3-methylthiophene as raw material. Let it react with magnesium powder to make Grignard reagent, and then react with N, N-dimethylformamide. In this process, the purity of magnesium powder and the anhydrous and anaerobic conditions of the reaction system are crucial. When preparing Grignard reagent, the initiation reaction needs to be handled carefully. When Grignard reagent is prepared, the reaction with N, N-dimethylformamide also needs to be controlled conditions. After the reaction is completed, the target product can also be obtained after similar post-treatment steps.
Third, with the help of the rearrangement reaction of thiophene derivatives. Take a specific 3-methylthiophene derivative and make it rearrange under suitable catalyst and reaction conditions, and then introduce formyl groups. This method requires quite high catalyst requirements, and requires fine screening and regulation of reaction conditions to improve the yield and selectivity. After subsequent separation and purification, 3-methyl-2-thiophene formaldehyde can also be obtained.
All synthesis methods have their own advantages and disadvantages. In practical application, careful choices should be made according to the availability of raw materials, cost, yield and purity requirements.

3-Methyl-2-thiophene formaldehyde is an organic compound. When storing and transporting, many things need to be paid attention to to to ensure its quality and safety.
When storing, the first environmental conditions. It should be placed in a cool and well-ventilated place, away from fire and heat sources. This compound is prone to chemical reactions when heated, or even the risk of combustion and explosion, so the storage temperature should be maintained at a low level, generally 2-8 ° C. In addition, it is necessary to ensure that the storage area is dry, because it is quite sensitive to moisture. In contact with water or humid air, reactions such as hydrolysis may occur, causing it to deteriorate.
At the same time, it should be well sealed and stored. 3-Methyl-2-thiophene formaldehyde is volatile. Sealed storage can prevent its volatilization loss, and can also avoid contact with oxygen and other components in the air and be oxidized, which will affect its chemical properties. In addition, the storage place should be stored separately from oxidants, acids, alkalis, etc., and must not be mixed. Because it may react violently with these substances and cause danger.
When transporting, there are also many points. Appropriate packaging needs to be selected. The packaging should be strong and well sealed, which can effectively prevent leakage. During transportation, it is necessary to ensure that the container does not collide or dump, so as to avoid chemical leakage caused by packaging damage. Transportation vehicles should be equipped with corresponding fire equipment and leakage emergency treatment equipment. In the event of an accident, they can be responded to in time.
In addition, transportation personnel must be familiar with the properties of 3-methyl-2-thiophene formaldehyde and emergency treatment methods. During transportation, pay close attention to environmental factors such as temperature and humidity. In case of high temperature weather, necessary cooling measures should be taken. In case of leakage, the leaked contaminated area should be quickly isolated, personnel should be restricted from entering and leaving, and appropriate treatment methods should be taken according to the chemical characteristics, such as absorption with inert materials such as sand and vermiculite, or neutralization with suitable chemical reagents to avoid pollution and harm to the environment.
