4-Fluoro-Benzenemethanamine is 4-fluorobenzamine. The method of synthesizing this compound can follow the following steps.
4-fluorobenzoic acid can be selected as the starting material. First, 4-fluorobenzoic acid is co-heated with thionyl chloride, and this reaction can convert the carboxyl group to an acyl chloride group to generate 4-fluorobenzoyl chloride. The chemical reaction formula is: 4-fluorobenzoic acid + SOCl ³ → 4-fluorobenzoyl chloride + SOC ² ↑ + HCl ↑. This reaction needs to be carried out under heating conditions. Sulfinyl chloride not only acts as a reactant, but also acts as a solvent. The reaction is more efficient, and the by-product sulfur dioxide and hydrogen chloride gas are easy to escape from the system, which is convenient for product separation.
Then, the obtained 4-fluorobenzoyl chloride is reacted with excess ammonia gas. The ammonia gas undergoes an aminolysis reaction with the acyl chloride group, and the acyl chloride group is replaced by an amino group to obtain 4-fluorobenzamide. The reaction formula is: 4-fluorobenzoyl chloride + 2NH 🥰 → 4-fluorobenzamide + NH Cl. This reaction is usually carried out under low temperature conditions to avoid side reactions. Excess ammonia can promote the forward reaction and improve the yield.
Finally, the reduction reaction of 4-fluorobenzamide is carried out. Using lithium aluminum hydride (LiAlH) as the reducing agent, in anhydrous ether and other organic solvents, lithium aluminum hydride can reduce the amide group to amino group, and successfully prepare 4-fluorobenzamide. The reaction formula is: 4-fluorobenzamide + LiAlH→ 4-fluorobenzamide. The reaction needs to be operated in an anhydrous and anaerobic environment, because lithium aluminum hydride will react violently in contact with water and oxygen, and excess aluminum hydride needs to be carefully handled after the reaction to prevent danger. Through this series of reactions, 4-Fluoro-Benzenemethanamine can be effectively synthesized.

4 - Fluoro - Benzenemethanamine, Chinese name 4 - fluorobenzamine, there are several important items to pay attention to when storing and transporting this substance.
Let's talk about storage first. First, you must find a cool, dry and well-ventilated place. Because if it is in a high temperature and humid place, this substance may react with water vapor and other components in the air, causing it to deteriorate. Second, you must keep away from fires and heat sources. Because of its flammability, in case of open flames and hot topics, there is a risk of combustion or even explosion. Third, the storage place should be separated from oxidants, acids, etc. 4-Fluorobenzamine is chemically active and in contact with oxidants, it is easy to trigger a violent oxidation reaction; coexisting with acids, or reactions such as acid-base neutralization, will damage its purity and properties. Fourth, storage containers are also particular, and well-sealed containers must be used to prevent leakage. And the material of the container should not chemically react with 4-fluorobenzamine, glass, specific plastic materials, etc. may be suitable choices.
As for transportation, first of all, the transportation vehicle should be equipped with corresponding fire protection equipment and leakage emergency treatment equipment. In case of leakage and other emergencies on the way, it can be dealt with in time to reduce the damage. Second, when transporting, ensure that the container does not leak, collapse, fall, or damage. Road bumps, sudden braking, etc. may cause damage to the container and cause leakage. Third, during transportation, you should prevent exposure to the sun, rain, and high temperature. In summer, the temperature in the carriage is easy to rise, and 4-fluorobenzamine is unstable at high temperatures; if rainwater seeps into the container, it will also affect its quality. Fourth, transport according to the specified route, do not stop in densely populated areas or prosperous areas. Once an accident such as leakage occurs, it will cause greater harm in densely populated areas. In short, 4-fluorobenzamine storage and transportation need to be cautious and operated according to specifications to ensure safety.

4 - Fluoro - Benzenemethanamine is an organic compound, and its safety risk should not be underestimated. This substance may be toxic and pose a potential threat to human health. If inhaled inadvertently, it may cause respiratory irritation, causing cough, asthma and other diseases; contact with the skin, or cause allergies, redness, swelling, itching; if eaten by mistake, it may damage the digestive system and involve the liver, kidneys and other organs.
In terms of the environment, it enters the water body, soil, or affects the ecological balance, and is toxic to aquatic organisms, soil microorganisms, etc., destroying the ecosystem.
When using this substance, be sure to operate strictly in accordance with safety procedures. Workers work in protective clothing, protective gloves and goggles, and work with good ventilation to prevent inhalation of its volatile gases. In case of accidental contact, rinse with plenty of water as soon as possible and seek medical attention if necessary.
When storing, store in a cool, dry and ventilated place, away from fire and heat sources, and store separately from oxidants and acids to prevent dangerous reactions.
In short, the safety risks of 4 - Fluoro - Benzenemethanamine must not be taken lightly, and should be treated with caution to ensure that personnel safety and the environment are not damaged.
