The name of this compound is derived from its structural characteristics. "Benzenethiol" is also called benzenthiophenol, which means that on the benzene ring, there is a thiol group (-SH) connected to it, which is the basic skeleton of the compound.
"P-chloro", "P" stands for para -, that is, at the position opposite to the thiol group, there is a chlorine atom (-Cl) to replace the hydrogen atom on it.
And in "s-chloromethyl", "s" or a specific label, "chloromethyl" is chloromethyl (-CH ³ Cl), which is also connected to the benzene ring.
In summary, the structure of this compound is on the benzene ring, with the thiol group and the chlorine atom in a para-position distribution, and the other chloromethyl group is connected to the benzene ring. Its structure is roughly like this, and the beauty of chemistry is evident here.
In terms of its appearance, under room temperature, it often appears as a colorless to slightly yellow liquid, with a flowing state. It looks like a clear spring, but it is not as pure as that clear spring. It has a special smell, pungent and strong, and the smell is impressive, as if to warn that this thing is unusual.
As for the boiling point, according to common sense, it is about a certain range, which depends on its molecular structure and intermolecular forces. Intermolecular forces include van der Waals forces, etc., which cause it to absorb considerable heat in order to break free from the bonds between molecules and transform from liquid to gaseous.
The melting point also has its specific value. When the temperature drops to a certain critical point, the molecular motion slows down, gets close to each other, and finally solidifies into a solid state. The density of this substance is different from that of water. In the density measurement experiment, the relationship between its density and water can be clarified, and then its floating and sinking state in water can be inferred.
In terms of solubility, in organic solvents, such as ethanol, ether, etc., there is a certain solubility. Due to the principle of "similarity and miscibility", its molecular structure is similar to that of organic solvents, and the force between them can promote them to mix with each other. However, in water, its solubility is not good, because the molecular structure of water molecules and P-chloro-s-chloromethylbenzene mercaptan is quite different, it is difficult to form an effective force to achieve mutual solubility.
These physical properties are of great significance in many fields such as chemical industry and scientific research, providing a key basis for its separation, purification, application and other operations.
First, in the field of organic synthesis, it is often used as a key intermediate. In the art of organic synthesis, in order to create complex and delicate organic molecules, it is necessary to gradually build a variety of compounds as the basis. P-chloro-s-chloromethylbenzene mercaptan has a specific chemical structure and activity, and can be linked with other compounds through chemical reactions to form new carbon-sulfur bonds or other chemical bonds, and then derive other types of organic compounds. For example, it can react with compounds containing nucleophilic groups, such as alcohols and amines, and obtain thioethers or thiamines with special functions through nucleophilic substitution reactions. This is of great value in the fields of medicinal chemistry and materials science.
Second, it is also useful in pharmaceutical research and development. To create new drugs, medical chemists often need to explore molecular structures with unique biological activities. P-chloro-s-chloromethylbenzenthiol and its derived compounds may have specific biological activities and can interact with proteins, enzymes and other macromolecules in vivo. It may regulate the activity of enzymes or affect the signaling pathways of cells, which is expected to develop drugs to treat specific diseases. Although it is itself or not a direct drug, it provides a key starting material and structural template for the development of drugs.
Third, it also has potential uses in the field of materials science. Modern materials science pursues the creation of new materials with specific properties. P-chloro-s-chloromethylbenzene mercaptan may participate in the preparation process of materials and endow materials with special properties. If it is introduced into the structure of polymer materials, it may change the surface properties, thermal stability, mechanical properties, etc. With its special properties of sulfur atoms, it may realize the functions of cross-linking and modification of materials, thereby meeting the diverse needs of material properties in different fields.
First, a suitable benzene substrate should be taken. This substrate should have a modifiable group to facilitate the subsequent introduction of chlorine, chloromethyl and mercapto groups. If chlorobenzene is used as the starting material, chlorine atoms can be introduced at specific positions in the benzene ring by halogenation reaction. The method can react with chlorine gas in the presence of light or catalysts such as iron filings, so that the chlorine atoms can be located and connected to obtain benzene derivatives containing specific chlorine substitutions.
The second time, chloromethyl is introduced. It can be reacted by chloromethylation, often with polyformaldehyde and hydrogen chloride as raw materials, and reacted with the previous product under the catalysis of suitable catalysts such as zinc salts. In this process, the reaction temperature and the proportion of the material need to be controlled well, so that the chloromethyl can be selectively connected to the specific position of the benzene ring to obtain the chlorobenzene product containing chloromethyl.
As for the introduction of sulfhydryl groups, the above products are often reacted with sulfur-containing reagents such as sodium hydride. This reaction also needs to pay attention to conditions, such as the pH and temperature of the reaction medium. Under suitable alkaline conditions, hydrogen sulfide ions can replace suitable leaving groups, so as to access sulfhydryl groups, and finally obtain P-chloro-s-chloromethylbenzenethiol.
Every step of the synthesis process needs to be precisely controlled, from the purity of the raw material, the reaction conditions to the separation and purification of the product, all of which are related to the quality and yield of After each step of the reaction, it is often necessary to purify the product by distillation, recrystallization, column chromatography, etc. to remove impurities and obtain a pure target product.
The first priority is safety, and this compound has a certain degree of danger. It may be irritating, and it may cause damage to the skin, or even damage. Therefore, when using the oil, it must be protected by protective devices, such as gloves, eyes, etc., so that the skin and eyes are protected from it. If you accidentally contact the oil, quickly wash it with a lot of water, and it is necessary to seek treatment.
In addition, its taste or bad, and in the air, or have a bad nature. Therefore, it is advisable to operate it well to prevent inhalation, and breathing. If the operation does not taste normal, it will stop immediately, and the application will be carried out through the process to ensure the safety of the environment.
And its transformation and activity, in the event of storage, pay attention to the source of fire and fire. When mixing other things, it is necessary to understand the anti-reaction characteristics of the two first, so as to prevent the generation of strong reactions and cause danger. And store it in a dense container, place it in a dry place, and avoid direct light.
In addition, the utensils used must be cleaned when they are used, so as to prevent the shadow of the things left behind from being used next time, and to avoid corrosion of the utensils. The process of operation is easy to check on the day, and it is beneficial to track the potential of life. Therefore, be careful and follow the rules to ensure the safety of use and the effectiveness of this thing.
