What is the chemistry of 4-chlorobenzenesulfonamide?
4-Chlorobenzenesulfonamide is one of the organic compounds. Its shape is usually white crystalline powder, with specific physical and chemical properties.
In terms of chemical properties, this compound contains a sulfonamide group and a chlorine atom, which give it unique activity. In the sulfonamide group, the nitrogen atom has lone pair electrons and can participate in the formation of hydrogen bonds. Therefore, 4-chlorobenzenesulfonamide can be combined with compounds containing active hydrogen in hydrogen under appropriate conditions, which has a great impact on its solubility and interaction with other molecules.
Furthermore, the chlorine atom is an electron-withdrawing group, and its presence reduces the electron cloud density of the benzene ring. This electronic effect changes the electrophilic substitution activity of the benzene ring. Compared with benzene, the benzene ring of 4-chlorobenzenesulfonamide is more difficult to undergo electrophilic substitution reaction, and the substitution position is also affected by the positioning effect of the chlorine atom and the sulfonamide group.
In terms of acidity and alkalinity, the sulfonamide group can be weakly ionized and is weakly acidic. Because the hydrogen on the nitrogen atom can be partially dissociated, 4-chlorobenzenesulfonamide can react with bases in an alkaline environment to generate corresponding salts.
In addition, 4-chlorobenzenesulfonamide can participate in many chemical reactions, such as reactions with nucleoph Nucleophiles can attack the positions on the sulfonyl chloride group or benzene ring affected by chlorine atoms, so as to realize the structural modification and transformation of compounds, and have a wide range of uses in the field of organic synthesis. The diversity of their chemical properties makes them have important applications in many fields such as medicinal chemistry and materials science.

What is the preparation method of 4-chlorobenzenesulfonamide?
The preparation method of 4-chlorobenzenesulfonamide, according to the ancient method, is obtained by reacting 4-chlorobenzenesulfonyl chloride with ammonia.
First take an appropriate amount of 4-chlorobenzenesulfonyl chloride, which is the key raw material for the reaction. The preparation may be obtained by sulfonation of 4-chlorobenzene with chlorosulfonic acid. In a suitable reaction vessel, slowly add 4-chlorobenzene to the cooled chlorosulfonic acid, and the temperature should be carefully controlled to prevent overreaction. Stir to mix the two thoroughly. During the reaction process, the sulfonic acid group of chlorosulfonic acid replaces the hydrogen atom on the benzene ring to form 4-chlorobenzenesulfonyl chloride After the reaction is completed, the pure 4-chlorobenzenesulfonyl chloride is obtained through appropriate separation and purification steps.
The 4-chlorobenzenesulfonyl chloride is taken for the second time, and ammonia is slowly introduced into another reaction device. Ammonia gas reacts with 4-chlorobenzenesulfonyl chloride, and the chlorine atom in the sulfonyl chloride group is replaced by the amino group of ammonia to produce 4-chlorobenzenesulfonamide. During this reaction process, it is advisable to maintain certain temperature and pressure conditions to promote the forward progress of the reaction. At the same time, the reaction system may need to be stirred to fully contact the reactants and improve the reaction efficiency.
The reaction is completed, and the product may contain unreacted raw materials and by-products. A variety of separation and purification methods can be used, such as crystallization, extraction, column chromatography, etc., to obtain high-purity 4-chlorobenzenesulfonamide. For example, using the difference in solubility in different solvents, the crystallization operation is carried out to precipitate 4-chlorobenzenesulfonamide from the solution, and then the pure 4-chlorobenzenesulfonamide product is obtained through filtration, washing, drying and other processes.

What is the price range of 4-chlorobenzenesulfonamide in the market?
4-Chlorobenzenesulfonamide is in the market, and its price range is difficult to determine. This is a fine chemical category, and its price varies for many reasons.
Purity is the first end. If the purity is perfect and almost flawless, the price of such a good product will be high. If it contains impurities, although it can be used, the price will be low. For example, if the high purity reaches more than 99%, compared with 95% purity, the price can be far different.
Furthermore, the state of supply and demand also affects its price. When there are many people in the market, but the amount of production is small, and the supply is in short supply, the price must rise. On the contrary, if the supply exceeds the demand, the merchant wants to sell its goods quickly, and the price may drop.
The production method and cost are also the main reasons. If the new method is adopted, it is efficient and cost-effective, and the price may be competitive. And the old law production, the cost is high and the price is also high.
Regional differences also have an impact. Prosperous commercial ports, convenient transportation, low logistics costs, prices or slightly flat. In remote places, transportation is difficult, costs are superimposed, and prices rise.
And the effect of the brand, well-known large factories, outstanding reputation, strict quality control, their production of 4-chlorobenzenesulfonamide, the price is often higher than that of unknown small factories.
Roughly speaking, the lowest price may be tens of yuan per kilogram. If it is a high-purity, special-purpose product, it can reach hundreds of yuan per kilogram, and even more expensive. Market conditions are volatile, and prices vary day and night with changes in the market. It is necessary to observe in real time to know the exact price.
