What are the physical properties of Sodium 4-Hydroxybenzenesulfonate?

Sodium 4 - Hydroxybenzenesulfonate, or sodium p-hydroxybenzenesulfonate, is an organic compound. Its physical properties are many, as detailed below:
- ** Appearance properties **: This compound is often in the state of white crystalline powder, with fine texture and pure white color, like the first snow in winter, giving people a sense of purity. Its powdery form makes the particles fine and uniform, flickering slightly under light, like a shimmer in fine sand.
- ** Solubility **: Sodium p-hydroxybenzenesulfonate has good solubility in water, just like salt dissolves naturally and smoothly in water. When placed in water, it quickly interacts with water molecules and gradually diffuses and dissolves to form a uniform and transparent solution. This property is due to the interaction between its molecular structure and water molecules, which allows the two to be closely combined. However, it is not very soluble in organic solvents such as ethanol and ether, just like oil and water are difficult to melt. In these organic solvents, it often exists in solid form and is difficult to disperse and dissolve.
- ** Melting point **: The substance has a specific melting point, around 300 ° C. When the temperature gradually rises to the melting point, sodium p-hydroxybenzenesulfonate slowly changes from a solid state to a liquid state. This process is like melting snow. At a specific temperature, the forces between molecules change, and the lattice structure gradually disintegrates, thus realizing the transformation of the state of matter.
- ** Stability **: Under normal conditions, sodium p-hydroxybenzene sulfonate is quite stable, just like a strong fortress, and it is not easy to react with common substances in the air, such as oxygen and carbon dioxide. Even over time, its chemical properties can remain basically unchanged. However, it should be noted that it should avoid contact with strong oxidants and other substances, otherwise it may cause chemical reactions, just like placing flammable materials near the fire source, which is easy to cause danger and damage the stability.

What are the chemical properties of Sodium 4-Hydroxybenzenesulfonate?

The chemical properties of sodium-4-hydroxybenzene sulfonate are particularly important. This compound has ionic properties. Because it contains sodium ions and 4-hydroxybenzene sulfonate ions, it can be ionized in aqueous solution, resulting in its ability to exhibit electrolyte properties and conduct current.
Its solubility is also considerable. Generally speaking, it has good solubility in water, and its ionic structure can form a strong interaction with water molecules, that is, ion-dipole interaction, so it can be well dispersed in aqueous medium.
In terms of reactivity, the hydroxyl group in the 4-hydroxybenzene sulfonate group is nucleophilic and can participate in many nucleophilic substitution reactions. In case of suitable electrophilic reagents, the oxygen atom of the hydroxyl group can provide electron pairs, bond with electrophilic reagents, and derive new compounds.
Furthermore, the benzene ring is also a reactive site. Because the benzene ring has an electron-rich conjugated system, it is vulnerable to attack by electrophilic reagents, triggering electrophilic substitution reactions such as halogenation, nitrification, and sulfonation.
In addition, it may also participate in acid-base reactions. Hydroxyl groups can release protons, although they are less acidic, they can undergo acid-base neutralization in a specific alkaline environment, resulting in changes in molecular structure and properties. The sulfonic acid group is acidic and can react with bases to form salts, which is of great significance in many organic synthesis and industrial applications.

What is the production method of Sodium 4-Hydroxybenzenesulfonate?

The method of making sodium and sodium 4-hydroxybenzenesulfonate is quite exquisite. In the past, the method started with phenolic compounds. Take pure phenol and place it in a special reactor. This kettle needs to be able to resist acid and alkali and high temperature. Slowly add an appropriate amount of fuming sulfuric acid to the kettle. This process needs to be carefully controlled, and it should not exceed 60 degrees Celsius. Due to the strong corrosiveness and reactivity of fuming sulfuric acid, excessive temperature is prone to side reactions. Phenol and fuming sulfuric acid then sulfonate, and the sulfuric acid group is cleverly connected to the phenyl ring hydroxyl group to form 4-hydroxybenzenesulfonic acid. This reaction takes a long time and requires continuous stirring to make the reactants fully contact and react evenly.
After the reaction is completed, a mixed solution containing 4-hydroxybenzenesulfonic acid is obtained. Then slowly add sodium hydroxide solution to it. This step also requires careful temperature control to neutralize the acid and base, and the pH value gradually becomes neutral. 4-hydroxybenzenesulfonic acid reacts with sodium hydroxide to precisely generate 4-hydroxybenzenesulfonic acid. After neutralization, the mixed solution may contain impurities, and separation and purification are carried out. It is often used as a crystallization method. The mixture is cooled down, the solubility of 4-hydroxybenzenesulfonic acid decreases, and crystallization precipitates from the solution. The crude product of 4-hydroxybenzenesulfonic acid is obtained by filtering. After recrystallization, it is repeatedly washed with an organic solvent to remove residual impurities to obtain pure 4-hydroxybenzenesulfonic acid.
As for the preparation of sodium, in ancient times, electrolysis of molten sodium chloride was often used. In a special electrolytic cell, refined molten sodium chloride is used, graphite is used as the anode, and iron rods are used as the cathode. With direct current, sodium chloride loses electrons at the anode to form chlorine gas and escapes. At the cathode, sodium electrons are precipitated, attached to the surface of the cathode, and collected to obtain metallic sodium. However, this process consumes a lot of energy and requires strict protection. Due to the toxicity of chlorine gas, sodium is chemically active and reacts violently in contact with water. In summary, the preparation of sodium and sodium 4-hydroxybenzenesulfonate requires following the procedures to obtain good products.

What are the precautions for Sodium 4-Hydroxybenzenesulfonate in storage and transportation?

4 - Sodium hydroxybenzene sulfonate is a chemical substance. When storing and transporting, many things need to be paid attention to to ensure safety.
First, the storage environment should be carefully selected. It should be placed in a cool, dry and well-ventilated place, and must not be exposed to high temperature and humid environment. High temperature can easily cause chemical reactions of the substance, which affects its quality; moisture may cause it to deteriorate. For example, if it is stored in a dark and humid basement, it is very easy to have such a situation.
Second, the packaging must be tight. It needs to be packed in a well-sealed container to prevent contact with air, moisture, etc. This can prevent the substance from evaporating, oxidizing or absorbing moisture and changing its own properties. If the package is damaged, sodium 4-hydroxybenzenesulfonate is easy to interact with external substances.
Third, the transportation process cannot be ignored. Make sure it is stable, avoid collisions and bumps, and prevent packaging damage. And it needs to be transported in isolation from other chemicals, especially those substances that may react with it. For example, it should not be transported by car with strong oxidants, strong acids and alkalis, otherwise dangerous chemical reactions may be caused.
Fourth, fireworks should be strictly prohibited in storage and transportation places. Although sodium 4-hydroxybenzenesulfonate is not flammable and explosive, if there is an open flame around it, it may indirectly cause danger due to other factors. At the same time, corresponding fire equipment and emergency treatment equipment need to be equipped for emergencies.
Fifth, whether it is storage or transportation, there must be clear and clear labels, marking the name of the substance, properties, hazards and other information. Relevant operators also need to undergo professional training, familiar with its characteristics and safety operating procedures, so as to ensure the safety of 4-hydroxybenzenesulfonate storage and transportation in all links.
