What are the physical properties of 3-Chloro-4-Aminobenzotrifluoride?
3-Chloro-4-aminotrifluorotoluene is one of the organic compounds. Its physical properties are worthy of detailed observation.
Looking at its appearance, it often shows a crystalline powder like white to light brown, which is easy to identify. Under the eye, the state of its fine particles can be observed.
When it comes to the melting point, it is about 39-43 ° C. The melting point is the critical temperature at which the substance changes from solid to liquid. In this temperature range, the intermolecular force of the compound can just cause the solid structure to disintegrate, and then it becomes liquid. The characteristics of this melting point are an important reference for the identification, separation and purification of the substance.
The boiling point is about 254 ° C. The boiling point is the temperature at which the saturated vapor pressure of the liquid is equal to the external pressure. When this boiling point is reached, the molecule of 3-chloro-4-aminotrifluorotoluene is energized enough to overcome the constraints of the liquid phase and escape into the gas phase. This boiling point value is of great significance in the operation of distillation in chemical production.
Furthermore, its solubility is also a key physical property. In organic solvents such as ethanol, ether, and acetone, 3-chloro-4-aminotrifluorotoluene has good solubility. This is because the molecular structure of these organic solvents has a chemical affinity with the compound, which can make the molecules uniformly disperse. However, the solubility in water is not good, and the difference between the polarity of water and the structure of the compound makes it difficult for the two to blend. The characteristics of this solubility affect its reaction and application scenarios in different media.
In terms of density, it is about 1.42g/cm ³. The density represents the mass of the substance per unit volume. This value reflects the compactness of its molecular accumulation. It is an indispensable parameter in practical applications such as stoichiometry involving mass and volume conversion and material transportation and storage.
In addition, its stability also belongs to the category of physical properties. Under normal environmental conditions, 3-chloro-4-aminotrifluorotoluene has certain stability, but in case of high temperature, open flame or strong oxidant, the stability is damaged and it is easy to cause chemical reactions. This stability feature requires careful consideration and precautions during its storage and use.
What are 3-Chloro-4-Aminobenzotrifluoride synthesis methods?
The synthesis method of 3-chloro-4-aminotrifluorotoluene has been around for a long time, and with the passage of time, it has become more and more complicated and delicate. The following are the common methods.
First, 3-chloro-4-nitrotrifluorotoluene is used as the starting material, and the target product is obtained by reduction method. In the past, iron powder and hydrochloric acid systems were mostly used. The reaction was as follows: 3-chloro-4-nitrotrifluorotoluene was placed in a reactor with iron powder and hydrochloric acid, and slowly heated. During the process, the iron powder was eroded by hydrochloric acid, and the released hydrogen atoms gradually reduced the nitro group to an amino group. Although this process is relatively simple to operate, the amount of iron powder is quite large, and after the reaction is completed, the treatment of waste iron filings is complicated and easy to cause environmental pollution. Later, the catalytic hydrogenation method is replaced, and palladium carbon, platinum carbon, etc. are often used as catalysts to reduce in hydrogen atmosphere. This method has relatively mild reaction conditions, high product purity, and no fear of iron sludge, and has gradually become the mainstream. For example, under appropriate temperature and pressure, the ethanol solution of 3-chloro-4-nitrotrifluorotoluene and palladium carbon catalyst are co-placed in an autoclave, and hydrogen is introduced. After several times of reaction, high-purity 3-chloro-4-aminotrifluorotoluene can be obtained.
Second, starting from fluoroaromatic hydrocarbons, it is synthesized through a series of steps such as halogenation, nitration, and reduction. First, fluoroaromatic hydrocarbons are halogenated under appropriate conditions, and chlorine atoms are introduced. For example, chlorine and ferric chloride are used as halogenation systems, so that aromatic hydrocarbons and chlorine gas are substituted under the catalysis of ferric chloride, and chlorine atoms are introduced at specific positions in the benzene ring. Then nitrification is carried out, and the nitro group is treated with mixed acid (a mixture of concentrated sulfuric acid and concentrated nitric acid), so that the nitro group is precisely positioned and in a suitable position with the chlorine atom. Finally, as mentioned earlier, the nitro group is converted into an amino group by catalytic hydrogenation or chemical reduction, thereby obtaining 3-chlor The length of this route lies in the easy availability of raw materials. Although there are many steps, the reaction of each step is relatively mature, and the reaction conditions can be flexibly adjusted according to actual needs to obtain the best yield and purity.
Third, there are also other compounds containing nitrogen, chlorine, and fluorine synthesized by coupling reactions. For example, a specific chlorofluorine-containing halogenated aromatic hydrocarbon and an amino-containing compound are coupled under palladium catalysis. This reaction requires fine regulation of the reaction conditions and requires a high catalyst. However, it has the advantages of high atomic economy and few side reactions. At the moment of pursuing green chemical synthesis, it has great research and application potential.
What are the precautions in storage and transportation of 3-Chloro-4-Aminobenzotrifluoride?
For 3-chloro-4-aminotrifluorotoluene, many precautions need to be paid attention to during storage and transportation.
This substance has certain chemical activity, and when stored, the first environment is dry. Because moisture can easily induce its chemical reaction and damage its quality. The warehouse should be selected in a cool place, and strict protection against rainwater leakage.
Temperature is also critical. It should be stored in a cool place to avoid heat. High temperature may cause it to decompose, evaporate, and even pose a risk of safety. Therefore, the warehouse needs to be equipped with cooling facilities, such as air conditioners, ventilation devices, etc.
Furthermore, the substance must be stored in isolation from oxidants, acids, alkalis, etc. These substances meet with it, or react violently, causing the disaster of ignition.
When transporting, the packaging must be sturdy. Use suitable packaging materials, such as special iron drums, plastic drums, etc., to ensure that it will not be damaged or leaked during transportation.
Transportation vehicles should also be clean, dry, and prohibited from mixing with the above-mentioned objects. During driving, drivers should drive slowly and steadily to avoid bumps and vibrations and prevent damage to the packaging.
When loading and unloading, operators should be cautious and wear protective equipment, such as gloves, goggles, etc. It is strictly forbidden to drop or press lightly to avoid packaging cracking, material leakage, and endangering the environment and personal safety.
In short, the storage and transportation of 3-chloro-4-aminotrifluorotoluene is related to safety and quality, and all aspects must be strictly adhered to, and must not be slack and negligent.
