Furthermore, the introduction of fluorine atoms gives the compound special properties. Fluorine atoms have high electronegativity, which can enhance molecular polarity and affect their physical and chemical properties. For example, it may affect the solubility of compounds, solubility in some organic solvents or different from fluorine-free analogs.
And due to the influence of fluorine atoms on the distribution of electron clouds in the benzene ring, the reactivity and selectivity of the benzene ring will be changed. In electrophilic substitution reactions, the localization effect of fluorine atoms will tilt the reaction check point to a specific position, and the distribution of reaction products is different compared with non-fluorinated phenylenediamines.
In addition, in terms of stability, fluorine atoms are connected to the benzene ring and amine groups. Due to the higher C-F bond energy, molecular stability is enhanced to a certain extent. In some chemical reactions or environments, their stability is different from that of similar substances without fluorine.

The method of preparing 1,2-phenylenediamine and 3,5-difluorine has been used in ancient times, and is described in detail below.
First take benzene as the starting material, which is a common chemical raw material. After halogenation, fluoride is reacted with fluoride in a specific reaction vessel, and a suitable temperature and pressure are set to introduce fluorine atoms at a specific position on the benzene ring to obtain fluorinated benzene derivatives. This step requires fine regulation of the reaction conditions. If the temperature is too high, side reactions will occur, and if it is too low, the reaction will be delayed and difficult to achieve.
Then, nitrification of fluorinated benzene derivatives is performed. With a specific nitrifying reagent, react in a suitable medium to introduce the nitro group into the benzene ring, and locate it accurately to obtain a benzene compound containing fluorine and nitro groups. This process also requires careful temperature control and the proportion of reagents to prevent the position deviation of nitro substitution or excessive nitrification.
Then the compound containing fluorine and nitro is reduced by the method of reduction to convert the nitro group into an amino group. Commonly used reducing agents such as the combination of metal and acid, or catalytic hydrogenation. In this step, the choice of catalyst and the control of the reaction environment are crucial to ensure that the nitro group is completely reduced to an amino group without damaging the structure of the fluorine atom and the benzene ring.
After the above steps of reaction, the method of separation and purification is added. Using methods such as distillation, extraction, recrystallization, etc. to remove impurities in the reaction system to obtain pure 1,2-phenylenediamine and 3,5-difluorine products. Every step of the operation needs to follow the delicacy of ancient methods and combine current technology to make the preparation process smooth and the product excellent.

First, this product is toxic. If inadvertently touched, whether it is penetrated through the skin, inhaled its dust, vapor, or taken by mistake, it will cause damage to the human body. After skin contact, it may cause redness, swelling, itching, and pain; after inhalation, it is easy to cause respiratory tract irritation symptoms, such as cough, asthma, etc. If swallowed inadvertently, it may cause serious effects on the stomach and even the organs of the whole body. Therefore, when operating, be sure to be fully armed, wear protective clothing, protective gloves and gas masks, and beware of contact with them.
Second, it is flammable. In case of open flames and hot topics, it is very easy to burn and may even cause an explosion. Storage and use places should be kept away from fire and heat sources, and fireworks are strictly prohibited. At the same time, suitable fire extinguishing equipment should be equipped for emergencies.
Third, it is also harmful to the environment. Once it enters the environment, it may cause pollution to water bodies, soil, atmosphere, etc., affecting the ecological balance. During use, be sure to properly dispose of waste and must not discharge it at will.
Fourth, storage is also exquisite. Store in a cool, ventilated place, away from fire and heat sources. It should be stored separately from oxidants, acids, etc., and should not be mixed. The storage area should be equipped with suitable materials to contain leaks.
In short, the operation of 3,5-difluoro-1,2-phenylenediamine must be vigilant at all times and strictly follow safety operating procedures, so as to ensure personal safety and environmental safety.
