In the field of medicine, it may be used as a raw material for antibacterial drugs. Because of its unique structure, it has certain antibacterial properties, or it can be chemically modified to produce better antibacterial agents to fight against various pathogens from infecting the human body and protecting the well-being of the people.
In the field of pesticides, this compound may be used as a key ingredient in insecticides and fungicides. Due to its chemical properties, it may be able to effectively inhibit the reproduction of pests, kill bacteria, and protect crops from diseases and insect pests, making the harvest of crops promising and maintaining the foundation of people's livelihood.
In the dye industry, N-chloro-N-phenylbenzenesulfonamide may provide raw materials for the synthesis of new dyes. With its structural characteristics, it may endow the dye with unique color and properties, making the dyed material more vivid and lasting, in order to meet the needs of all parties for color.
With its characteristics, this compound plays an important role in the pharmaceutical, pesticide, dye and other industries, providing support for the development of all walks of life and far-reaching impact.
Looking at its properties, under room temperature and pressure, it is mostly white to light yellow crystalline powder, which is easy to store and handle. Its odor is slight and does not have a strong pungent taste, which can reduce sensory discomfort in actual operation.
When it comes to melting point, it is about [X] ° C. The melting point is set. When heating or melting treatment, there is a clear temperature basis, which can ensure accurate operation.
Solubility is also an important property. In organic solvents such as ethanol and acetone, it has a certain solubility. If it is soluble, it can be used for the reaction of solution systems or the preparation of related preparations. However, in water, the solubility is not good. This characteristic can be used in the process of separation and purification. It can be effectively separated by the difference in solubility between water and organic solvents.
In addition, its density is also fixed, about [X] g/cm ³. The value of density is very important in mixed systems or in the case of volume and mass conversion. It can provide basic data for experimental design and industrial production.
Its stability is acceptable, and it is not easy to decompose or react violently under normal environmental conditions. However, under special conditions such as high temperature and strong oxidants, the stability may be affected, which requires special attention when storing and using.
In summary, the physical properties of N-chloro-N-phenylbenzenesulfonamide play a key guiding role in the application of chemical industry, medicine and many other fields.
It is oxidizing. Due to the presence of chlorine atoms, the chlorine atom is in a higher oxidation state and can be used as an oxidant in many reactions. In case of reducing substances, the electrons that can be obtained by the chlorine atom are reduced, and the oxidation state itself is reduced, thereby oxidizing the substance that reacts with it.
In the nucleophilic substitution reaction, the benzenesulfonamide part of the compound, because the nitrogen atom is connected with an electron-absorbing benzenesulfonyl group, reduces the electron cloud density of the nitrogen atom, making it vulnerable to the attack of nucleophilic reagents and nucleophilic substitution occurs. Nucleophiles can attack nitrogen atoms and replace chlorine atoms to form new nitrogen-containing organic compounds.
Its stability is also worthy of attention. Affected by the conjugation effect of benzene ring, the molecular structure is relatively stable. The conjugate system of benzene ring can disperse electrons, reduce the molecular energy and enhance the stability. However, under certain conditions, such as high temperature, strong acid, and strong alkali environment, its structure will be affected, and decomposition or other reactions will occur.
In terms of solubility, because it is an organic compound, according to the principle of similar miscibility, it has better solubility in organic solvents such as ethanol, ether, and chloroform, but poor solubility in water. Because the main molecules are hydrophobic benzene ring and sulfonyl structure, it is difficult to form effective interactions with water molecules. The chemical properties of N-chloro-N-phenylbenzenesulfonamide make it widely used in the field of organic synthesis. It can be used as an oxidant and a raw material for nucleophilic substitution reactions to synthesize various organic compounds.
First take benzenesulfonyl chloride and place it in a reactor with aniline. Temperature control, accompanied by an appropriate catalyst, makes the two condensation reaction. In this process, the sulfonyl group of benzenesulfonyl chloride is combined with the amino group of aniline to obtain N-phenylbenzenesulfonamide. The reaction formula is roughly: benzenesulfonyl chloride + aniline → N-phenylbenzenesulfonamide + hydrogen chloride. After the reaction is completed, N-phenylbenzenesulfonamide is extracted with a suitable solvent, and pure N-phenylbenzenesulfonamide can be obtained through the separation and purification steps.
Then, the obtained N-phenylbenzenesulfonamide is dissolved in a suitable solvent, such as an inert organic solvent. Slowly add chlorine-containing reagents, such as sodium hypochlorite solution. In this process, the temperature, pH and other conditions of the reaction need to be carefully regulated. The chlorine atom will replace the hydrogen on the nitrogen atom in the N-phenylbenzenesulfonamide to obtain N-chloro-N-phenylbenzenesulfonamide. The reaction is roughly: N-phenylbenzenesulfonamide + chlorine-containing reagent → N-chloro-N-phenylbenzenesulfonamide. After the reaction is completed, after a series of post-treatment processes such as extraction, washing, drying, crystallization, etc., high-purity N-chloro-N-phenylbenzenesulfonamide products can be obtained. The whole preparation process, the conditions of each step are controlled as the key, which affects the purity and yield of the product.
First, this agent has a certain chemical activity. When storing, be sure to choose a cool, dry and well-ventilated place. If it is wet or hot, it may deteriorate and damage its effectiveness. And it must be placed separately from other chemicals, especially reducing substances, to prevent accidental chemical reactions.
Second, when using this agent, protective gear is indispensable. Wear protective clothing, gloves and goggles. Because it may be irritating to the skin and eyes, if it is accidentally touched, rinse it with plenty of water as soon as possible, and seek medical attention immediately.
Third, the operating environment is also the key. It is necessary to ensure smooth ventilation to prevent the accumulation of volatile gases, causing air pollution and endangering the human body. During the deployment or use process, the action should be slow and careful to avoid its splashing.
Fourth, the accurate dosage should not be ignored. Before use, study the reaction requirements and instructions carefully, weigh accurately, and the amount is large and small, which can affect the effectiveness of the reaction and the quality of the product.
Fifth, after use, dispose of the residue properly. Do not dump at will, and treat it harmlessly in accordance with relevant laws and regulations to avoid polluting the environment.
