What are the physical properties of 2,4-dichlorobenzenesulfonyl chloride?
2% 2C4-difluorobenzaldehyde oxime ether is a genus of organic compounds. Its physical properties are as follows:
Looking at its appearance, it often appears as a colorless to light yellow liquid or solid, which varies according to the specific chemical structure and purity. If the molecular arrangement is orderly and the interaction force is strong, it is easy to be solid; if the intermolecular force is weak and the movement is free, it is mostly liquid.
In terms of its solubility, it has good solubility in organic solvents such as ethanol, acetone, dichloromethane, etc. Interactions such as van der Waals force and hydrogen bonds can be formed between organic solvents and 2% 2C4-difluorobenzaldehyde oxime ether molecules, so that the solute molecules are uniformly dispersed in the solvent. However, in water, its solubility is poor. Because of its molecular structure, hydrophobic organic groups account for a large proportion, and the interaction with water molecules is weak, making it difficult to dissolve with water.
Talking about the melting point and boiling point, because the molecular structure contains fluorine atoms, fluorine atoms have strong electronegativity, which can cause intermolecular forces to change. Generally speaking, the melting point and boiling point of fluorinated organic compounds may be different from those of similar non-fluorinated compounds. The specific melting and boiling point of 2% 2C4-difluorobenzaldehyde oxime ether depends on the precise chemical structure, but it is roughly in a certain temperature range. Its melting point may be around tens of degrees Celsius, and the boiling point may reach hundreds of degrees Celsius. This requires a certain amount of energy to overcome the intermolecular forces in order to achieve phase transformation.
Its density is also an important physical property. Due to the specific type and quantity of atoms in the molecule, 2% 2C4-difluorobenzaldehyde oxime ether has a specific density, usually slightly greater than the density of water. This is due to the relative mass of the molecule and the degree of intermolecular packing.
The physical properties of 2% 2C4-difluorobenzaldehyde oxime ether are of great significance in chemical synthesis, materials science and other fields. Understanding its solubility is beneficial to select suitable solvents for reaction and separation; knowing the melting and boiling points can be used for purification and identification of substances; understanding the density is of guiding value for material balance and process design of related chemical processes.

What is the production method of 2,4-dichlorobenzenesulfonyl chloride?
2% 2C4-difluorobenzoyl chloride is an important intermediate in organic synthesis. The common preparation methods are as follows:
First, 2% 2C4-difluorobenzoic acid is used as the starting material and reacted with chlorination reagents. Among these chlorination reagents, sulfoxide chloride (SOCl ²) is often used. The reaction process is: 2% 2C4-difluorobenzoic acid interacts with sulfoxide chloride under suitable conditions, and the hydroxyl group (-OH) in the carboxyl group (-COOH) of the benzoic acid is replaced by a chlorine atom (-Cl) to generate 2% 2C4-difluorobenzoyl chloride, while by-products of sulfur dioxide (SO 2) and hydrogen chloride (HCl) gas. The reaction equation is roughly: $C_7H_4F_2O_2 + SOCl_2\ longrightarrow C_7H_3F_2ClO + SO_2 ↑ + HCl ↑ $. This reaction usually needs to be carried out under heating conditions, and an appropriate amount of catalyst, such as N, N-dimethylformamide (DMF), is often added to speed up the reaction rate and increase the yield.
Second, 2% 2C4-difluorotoluene is obtained by oxidation and chlorination. First, 2% 2C4-difluorotoluene is oxidized to a carboxyl group (-COOH) under the action of an appropriate oxidant to generate 2% 2C4-difluorobenzoic acid. The commonly used oxidizing agents are potassium permanganate (KMnO), potassium dichromate (K 2O Cr 2O O), etc. After that, the obtained 2% 2C4-difluorobenzoic acid is converted into 2% 2C4-difluorobenzoyl chloride according to the above reaction with thionyl chloride. This method is a little complicated, but the starting material 2% 2C4-difluorotoluene is relatively easy to obtain, and the cost may have certain advantages.
In addition, other fluorobenzene derivatives are used as starting materials to prepare 2% 2C4-difluorobenzoyl chloride through a series of reactions. However, due to the complex reaction steps, harsh conditions or rare raw materials, such methods are not as widely used as the first two.
