What are the physical properties of 2,3-dichlorobromobenzene?
2% 2C3 -dioxacyclohexane, this substance has strange properties and unique physical properties. Its color is transparent, like the clarity of morning dew, and it is a flowing liquid. It looks like smart water, but its properties are different.

is about -42 degrees Celsius. When it drops to Swain, the original smart state gradually condenses, as if time freezes, the liquid state turns to a solid state, and the molecular arrangement tends to be orderly from disorder, like a soldier array.
2% 2C3 -dioxane has a slightly lighter density than water. If you pour it into water, it can be seen that it floats on the water surface leisurely. The two are distinct, just like the incompatibility of oil and water.
Its solubility is also unique, and it can be miscible with many organic solvents such as alcohols and ethers, just like old friends reunite and blend with each other. However, in water, the solubility is limited, and it can only be partially dissolved, just like facing each other across the bank, making it difficult to fully integrate.
In addition, its volatility is strong, and it dissipates quietly in the air after a while, as if it is invisible. Its vapor is heavier than air, and it is easy to deposit in low places. If it is in a closed space, it is necessary to prevent its accumulation and cause hidden dangers.

What are the physical properties of 2,3-dichlorobromobenzene?
2% 2C3-dichlorobenzoic acid is an organic compound, and its physical properties are as follows:
In terms of view, this substance is usually in the state of white to light yellow crystalline powder. Smell it, or have a specific smell, but its taste is light and not pungent.
When it comes to the melting point, it is about 150-154 ° C. The melting point is quite high. Because of its strong intermolecular force, it requires more energy to disintegrate the crystal lattice and convert it from solid to liquid.
As for the boiling point, it is about 317 ° C. The higher boiling point also reflects the relatively strong interaction between molecules, and a higher temperature is required to vaporize it.
In terms of solubility, 2% 2C3-dichlorobenzoic acid is slightly soluble in water. This is because water is a polar solvent, and although the compound contains carboxyl groups (-COOH) that can form hydrogen bonds with water, there are still two chlorine atoms in the molecule, which reduces the overall polarity, and the non-polar part of the benzene ring is large, making it insoluble in water. However, it is soluble in some organic solvents, such as ethanol, ether, acetone, etc. In these organic solvents, it can be uniformly dispersed by virtue of the Van der Waals force between molecules and the dipole-dipole interaction.
The density is about 1.55 g/cm ³, which is higher than that of water. Therefore, if placed in water, it will sink to the bottom of the water. The physical properties of this compound are closely related to its molecular structure, which lays the foundation for its application in chemical, pharmaceutical and other fields.

What are the common synthesis methods of 2,3-dichlorobromobenzene?
The common synthesis method of 2% 2C3-dichloropropane is obtained by the high temperature substitution reaction of propylene and chlorine as raw materials.
Propylene and chlorine meet under high temperature conditions. The chlorine atom in the chlorine gas is greatly active due to high temperature, so it can substitution with the hydrogen atom of propylene. In the structure of propylene, its α-hydrogen atom is abnormally active, so the chlorine atom is replaced by α-hydrogen first. In this way, 2-chloropropene is obtained.
2-chloropropene is formed, and then it meets with chlorine. This time, the chlorine atom of the chlorine gas reacts with the hydrogen atom at the ortho position of the 2-chloropropene double bond. After an addition reaction, the final product is 2% 2C3-dichloropropane.
There is also a method of using 1% 2C3-dichloropropene as raw material. 1% 2C3-dichloropropene and hydrogen are added in the presence of a suitable catalyst. This catalyst is often a metal catalyst such as nickel and palladium. Under the action of the catalyst, the hydrogen molecule is split into a hydrogen atom, which is combined with the double bond of 1% 2C3-dichloropropene to obtain 2% 2C3-dichloropropane.
Furthermore, propanol is used as the starting material. Propanol first interacts with chlorination reagents, such as phosphorus trichloride and phosphorus pentachloride, and the hydroxyl group is replaced by chlorine atoms to obtain chloropropane. Chloropropane and chlorine under light or high temperature conditions undergo radical substitution reaction, and a second chlorine atom can be gradually introduced, and 2% 2C3-dichloropropane can also be obtained.
All kinds of synthesis methods have their own advantages and disadvantages. The method of using propylene as the raw material is easy to obtain, but the reaction conditions are more severe, and high temperature operation must be cautious. The method of using 1% 2C3-dichloropropene as the raw material has a relatively mild reaction, but the preparation of 1% 2C3-dichloropropene itself is not easy. The method of using propanol as raw material, although the steps are slightly complicated, the raw materials are widely sourced and the operation is relatively safe. Therefore, when actually synthesizing, when considering the availability of raw materials, the difficulty of reaction conditions, and the cost, etc., make a prudent choice.

If there are many people in the market who want it, it will be used for the development of pharmaceuticals, pesticides, dyes, etc., and the supply is limited, the price will increase; on the contrary, if there are few people who want it, the supply will exceed the demand, and the price may drop.
Second, the price of raw materials also has a great impact. The production of 2,3-dichlorobenzoic acid requires all kinds of raw materials. If the price of raw materials increases, the cost of the production will increase, and the price in the market will also increase. If the price of raw materials decreases, the cost will decrease, and the price will decrease accordingly.
Furthermore, whether the process is advanced or not, the policy guidance and control, and the transportation cost are all involved in its price. Good craftsmanship, the yield will increase, the cost will decrease, and the price may be cheap; the policy will help the price to stabilize; the transportation cost will increase, or the price will be high.
Roughly speaking, the current market price of 2,3-dichlorobenzoic acid is between [X] yuan and [X] yuan per kilogram. However, this is only an approximate number, and the actual price still needs to be examined in detail at that time and the local situation. Only by consulting the chemical material suppliers and observing the market conditions can we obtain the exact number.
