What are the physical properties of 2-chloro-1-nitro-3- (trifluoromethyl) benzene?
2-% -1-amino-3- (triacetyl) benzene, this product is polyphysical. Its external surface is often solid, and the shape may vary depending on the synthesized parts and the degree of strength, or it is a crystalline powder, or it is a microgranular appearance.
It is determined by the melting temperature, which is roughly equal to a certain degree of strength. This characteristic is one of the important factors of this product. Melting is affected by factors such as molecular force and crystallization. If the molecular force is applied, a higher energy is required to break the crystal lattice, resulting in an increase in melting temperature.
The boiling temperature is also a specific value. Under a specific condition, the required degree of boiling is required for the material to be melted from the liquid. The molecular weight and molecular force of the boiling temperature are closely related to each other. If the molecular weight of the phase is large and the molecular force is large, the boiling temperature is often higher.
In terms of solubility, the surface is different in different solubilities. For water, such as water, its solubility is limited. Due to the mismatch between the degree of molecular solubility and water, water molecules can effectively disperse the molecules. However, in some soluble molecules, such as ethanol, acetone, etc., the solubility phase is good, because there are similar forces in the soluble molecules, and the principle of similar dissolution is followed.
The density is also one of the physical factors, reflecting the amount of matter in the chemical position. The density depends on the amount of molecules and the density of molecular arrangement. If the molecular weight is heavy and the arrangement is dense, the density is large.
In addition, this substance may have a specific refractive index, which is the ratio of the sine value of the incident angle of the optical substance to the sine value of the refractive angle, which can reflect the molecular properties and aggregation properties of the substance.
The above-mentioned physical properties are important for the determination, fractionation, and use of 2-% -1-amino-3- (triethyl) benzene in different domains. Only by mastering its physical rationality can we make better use of this substance.
Is the chemical properties of 2-chloro-1-nitro-3- (trifluoromethyl) benzene stable?
The chemical properties of 2-% -1-amino-3- (trifluoromethyl) benzene are uncertain, and it is worth exploring. In this compound, the atomic activity is easy to be reactive. The amino group is a strong nuclear base and can be biochemically combined for many times. Trifluoromethyl compounds have high molecular density due to their fluorine atoms, which cause high molecular density and low molecular activity.
It is difficult to react to the environment of reaction. If it is acidic medium, amino groups may be reactive, and its nuclear properties are changed. In the environment of reaction, the atom may be taken and lead to the same reaction. And this compound exhibits special reaction activity to oxidizing the original reaction, or because of its special characteristics.
However, the determination of the chemical properties of 2-%-1-amino-3- (trifluoromethyl) benzene still depends on the reverse properties. Such as degree, solubility, etc., can affect the reverse direction. If the degree of solubility is high, or promote its decomposition; a specific solubility may increase or weaken the molecular force, which affects its qualitative.
Therefore, the chemical properties of 2-%-1-amino-3- (trifluoromethyl) benzene are determined. It is necessary to consider a number of factors in order to determine the degree of reaction characteristics in different situations.
What are the preparation methods of 2-chloro-1-nitro-3- (trifluoromethyl) benzene?
The method of 2-% -1-amino-3- (triacetyl) benzene can be followed as follows:
The first starting material is benzene, and the nitro group can be introduced. Under the action of the mixed acid of sulfuric acid and nitric acid, the benzene atom on the benzene is replaced by the nitro group to form nitrobenzene. In this step, the reaction rate needs to be controlled. Generally, it is maintained at 50-60 ° C, and it is easy to generate by-products such as polynitrobenzene.
To obtain nitrobenzene, the original nitro group is reacted to the amino group. With the original acid system, the nitrobenzene is reacted under the appropriate conditions, and the nitro group is gradually reacted to generate the most aniline. During the reaction process, attention should be paid to the acidity and reversal of the reaction system.
Aniline is then triacetylated. Triacetyl chloride or acetic anhydride can be used. In the presence of catalytic catalysts such as pyridine or triethylamine, the amino group of aniline is triacetylated. In the presence of bioacetylation, the triethyl group is introduced into the amino group position or the amino group position. In addition, 2-% -1-amino-3- (triethyl) benzene can be obtained.
Another way, nitrotoluene can be produced. First, nitrotoluene is oxidized, and methyl is oxidized to carboxyl groups. High-acid oxidation can be used, and nitrobenzoic acid can be obtained under suitable solution and reaction conditions. Then, as in the original step of nitrobenzene, the nitro group of nitrobenzoic acid is the amino group to obtain aminobenzoic acid. Then a series of inverse groups are introduced, such as the first carboxyl group and the acid chloro group that is easy to reverse, and then the triacetylated phase is introduced, and the triethyl group is introduced to obtain the target.
Or use other compounds with similar properties as starting materials, follow the basic principle of synthesis, and carefully synthesize the reaction path through the reduction of functional properties, the introduction and elimination of nitrobenzoic acids, so as to form 2-% 1-amino-3- (triethylyl) benzene. In the whole process, it is necessary to control the reaction components in each step, including degree, force, proportion of reaction materials and amount of catalyst, etc., and make good use of the means of extraction to improve the yield of the target materials.
What are the precautions for storing and transporting 2-chloro-1-nitro-3- (trifluoromethyl) benzene?
2-% -1-amino-3- (triethyl) indole, this substance is a delicate material. When it is stored in a hot summer sun, it is necessary to pay attention to the eventful situation in order to ensure its stability and avoid accidents.
The first one is the degree of survival. This compound should be stored in a low environment, usually 2 to 8 degrees Celsius. If the degree is high, it may cause it to dissolve and cause it to decompose or collapse. If you are under the hot summer sun, the ice will melt quickly, and so will this compound. Under the high temperature, it will preserve its original quality.
The second time, you need to pay attention to the degree of the environment. In the tidal environment, it is easy for the compound to absorb moisture. It absorbs moisture, or causes it to be damaged, or changes its chemical properties. Therefore, if it is not stored, it is better to be dry and clear. It is like an ancient treasure, and it must be dried in a cool place, so as to prevent the material from being invaded.
Furthermore, it is very important to keep the package in a suitable container, and the container has a good sealing property to prevent leakage. If this compound is leaked, it will not be damaged, and it is more likely to endanger the safety of people in the surrounding environment. In addition to the container, there are also excellent materials to prevent shock and collision. If it is sent to the container, it must be fixed and properly prevented.
In addition, during the process, avoid oxidation, acid and other substances from being connected. This compound is special, and when the above-mentioned objects meet, it is easy to cause strong reactions and reactions, such as fire and fire, and it will form a large one. Therefore, if it is not easy to do so, it must be separated from this material, and it will be safe to ensure a safe journey.
In this case, 2-%-1-amino-3- (triethyl) indole should be paid attention to the degree, degree, packaging and avoid the connection of specific objects, etc., so as to ensure its safety and effectiveness.
