What are the physical properties of 4-chlorobenzenesulphonic Acid?
4-Chlorobenzenesulfonic acid is a kind of organic compound. Its physical properties are particularly important, related to its application and characteristics.
Looking at its properties, it is mostly a white to light yellow crystalline solid at room temperature, like a fine powder or a small piece, which is easy to identify and dispose of.
When it comes to the melting point, it is about 133-137 ° C. The melting point is the critical temperature at which a substance changes from solid to liquid. This property is crucial when identifying and purifying the substance. When the temperature gradually rises near the melting point, 4-chlorobenzenesulfonic acid slowly melts from the solid state to the liquid state. This phase transition process can be measured by precise instruments.
Its solubility is also significant. 4-Chlorobenzenesulfonic acid is soluble in water and can dissociate ions in water, showing acidic characteristics. This is because of its sulfonic acid group, which is a strong hydrophilic group, which promotes the formation of hydrogen bonds and other interactions between the compound and water molecules, so it can be well dissolved. And in polar organic solvents such as ethanol and acetone, it also has considerable solubility. This solubility makes it widely used in various chemical reactions and industrial processes. It can be used as a reaction medium or a raw material participating in the reaction.
As for the density, it is about 1.74 g/cm ³. The density represents the mass of the substance per unit volume, and this value is helpful for accurate measurement and estimation of its dosage in actual operation. For example, when preparing a solution or conducting a mixed reaction, the exact volume or mass of the required substance can be calculated according to the density to ensure the accuracy and effectiveness of the reaction.
In addition, 4-chlorobenzenesulfonic acid is hygroscopic. It can absorb moisture from the air, causing its own state to change, or agglomeration or deliquescence. Therefore, when storing, it needs to be placed in a dry place to prevent it from deteriorating due to moisture absorption, affecting its chemical properties and application effects. These physical properties are interrelated and together define the use and behavior of 4-chlorobenzenesulfonic acid in many fields such as chemical industry and medicine.

What are the chemical properties of 4-chlorobenzenesulphonic Acid?
4-Chlorobenzenesulfonic acid is also an organic compound. Its properties are common to acids, and it can combine with alkali phases to produce corresponding salts and water. In case of sodium hydroxide, the two interact to obtain sodium 4-chlorobenzenesulfonic acid and water. This reaction is peaceful and belongs to the genus of acid-base neutralization.
The sulfonyl group of 4-chlorobenzenesulfonic acid is hydrophilic, so that it has a certain solubility in water. And its chemical activity is quite high, and the chlorine atom on the benzene ring can participate in a variety of substitution reactions. For example, under appropriate conditions, the chlorine atom can be replaced by other groups such as hydroxyl and amino groups to obtain different derivatives. This is a commonly used method in organic synthesis.
Furthermore, 4-chlorobenzenesulfonic acid can be used as a catalyst. In some organic reactions, it can speed up the reaction rate without being consumed. Due to its acidic properties, it can promote the progress of esterification reactions, reduce the activation energy required for the reaction, make the reactant molecules more prone to effective collisions, and then improve the reaction efficiency.
In addition, its stability is also worth mentioning. Under normal environmental conditions, 4-chlorobenzenesulfonic acid can maintain a relatively stable state. However, when encountering special chemical reagents such as strong oxidants, reactions such as oxidation may occur, resulting in changes in its structure and properties. Therefore, when storing, it is necessary to avoid contact with strong oxidants and other substances, and it should be placed in a cool and dry place to ensure the stability of its chemical properties.

What is the production method of 4-chlorobenzenesulphonic Acid?
The method of making 4-chlorobenzene sulfonic acid is not detailed in the ancient chemical book "Tiangong Kaiwu", but it can be deduced according to the principle of the same kind of sulfonic acid production method.
The method of sulfonation is often carried out by co-heating 4-chlorobenzene with sulfuric acid. The method is to put 4-chlorobenzene in a temperature-resistant kettle and slowly inject an appropriate amount of concentrated sulfuric acid. The kettle needs to be strong and corrosion-resistant to prevent the invasion of strong acids. Then, the heat gradually heats up, so that the temperature of the contents of the kettle gradually rises. When heating, it is necessary to stir frequently to make the materials mix evenly and the reaction is uniform.
At the time of the reaction, 4-chlorobenzene interacts with the sulfonic acid group (-SO-H) in sulfuric acid, and the sulfonic acid group replaces the hydrogen on the benzene ring to form 4-chlorobenzene sulfonic acid. However, this reaction is not achieved overnight, and it needs to be adjusted to temperature and pressure, and it should be observed in time. If the temperature is too high, the side reaction will start, resulting in impure products; if the temperature is too low, the reaction will be slow and take too long.
After the reaction is completed, pour the contents of the kettle into a large container containing water, dilute it with water, and dissolve the 4-chlorobenzene sulfonic acid into the aqueous phase. Then purify it by distillation, During distillation, temperature control allows impurities to escape first, retaining 4-chlorobenzenesulfonic acid; crystallization allows the solute to separate from the solution to obtain pure crystals; filtration to remove insoluble impurities, and finally obtains purer 4-chlorobenzenesulfonic acid.
There are also 4-chloroaniline as the starting material, which is first diazotized, and then reacted with sodium sulfite, and then converted into 4-chlorobenzenesulfonic acid in a series. However, this step is cumbersome and costly, so the method of 4-chlorobenzene sulfonation is more commonly used.
