4-Fluorobenzenecarbothioamide is 4-fluorobenzothiamide, and its synthesis method is as follows:
can be started from 4-fluorobenzoic acid. First, 4-fluorobenzoic acid is reacted with dichlorosulfoxide. This step is to use carboxylic acid and dichlorosulfoxide under heating conditions, and the hydroxyl group in the carboxyl group is replaced by a chlorine atom to generate 4-fluorobenzoyl chloride. During the reaction, it is necessary to control the temperature and reaction time in an appropriate reaction vessel to ensure that the reaction is fully carried out, and pay attention to the pungent odor of dichlorosulfoxide. The operation should be in a well-ventilated place.
The obtained 4-fluorobenzoyl chloride is then reacted with thioamidation reagents. It is common to react with thiourea in a suitable solvent and under alkaline conditions. During this process, the alkaline environment prompts the reaction to proceed in the direction of generating 4-fluorobenzothiamide. The choice of solvent is crucial, and it needs to be determined according to the solubility and reaction characteristics of the reactant and the product. Common organic solvents such as ethanol and dichloromethane can be tried. After the reaction is completed, separation and purification steps need to be carried out. High-purity 4-fluorobenzothiamide products can be obtained by methods such as column chromatography and recrystallization.
Or 4-fluorobromobenzene is used as the starting material, and the Grignard reagent is first reacted with magnesium, and then reacted with carbon disulfide to form a sulfur-containing intermediate, and then hydrolyzed and amidation steps can also be obtained. When preparing Grignard reagent, the reaction system needs to be anhydrous and oxygen-free to ensure a smooth reaction. The subsequent reaction steps also need to control the reaction conditions, and the corresponding separation and purification operations need to be carried out after each step of the reaction to improve the purity of the product.

4-Fluorobenzolamide is an organic compound, and many things need to be paid attention to when storing.
First, it is related to the storage environment. This compound should be placed in a cool, dry and well-ventilated place. If the ambient temperature is too high, it may cause thermal decomposition and cause chemical properties to change. Humid environment is also not advisable, because moisture or reaction with it will affect its purity and stability. For storage in ancient times, a dry and ventilated place must be selected, so that the quality of the protective material remains unchanged.
Second, it is necessary to avoid open flames and heat sources. 4-Fluorobenzolamide or flammable, in case of open flames, hot topics can easily cause combustion or even explosion, just like the ancients fire prevention, away from the fire heat source is the first thing.
Third, about packaging. Should use a well-sealed packaging container to prevent it from contacting with the air. Oxygen, carbon dioxide and other components in the air may react with 4-fluorobenzolamide to cause it to deteriorate. Just like the ancients sealed treasures, they must use a secret device to prevent external intrusion.
Fourth, it needs to be stored separately from oxidizing agents, acids, alkalis and other substances. Because of its chemical activity, it can mix with these substances, or trigger violent chemical reactions, resulting in dangerous conditions. Ancient objects were also classified and stored to prevent mutual influence.
Fifth, the storage area should be equipped with suitable containment materials. In the event of leakage, it can be collected and treated in time to avoid pollution to the environment. This is a precautionary measure, just like an ancient preparation, to cope with sudden changes. In short, the storage of 4-fluorobenzolamide must follow the above points carefully to ensure its quality and safety.

4-Fluorobenzenecarbothioamide, that is, 4-fluorobenzolamide, the impact of this substance on the environment is quite complex and needs to be analyzed in detail.

Different types of microorganisms have different decomposition capabilities and pathways for 4-fluorobenzolamide. Some microorganisms may be able to completely mineralize it and convert it into inorganic substances such as carbon dioxide and water; some may only convert it into other intermediate products, which continue to participate in various environmental processes in the soil.
