What are the chemical properties of Sodium 4-hydroxybenzene Sulfoate (dihydrate)

Sodium and sodium 4-hydroxybenzenesulfonate (dihydrate) have interesting chemical properties. Sodium, which is an active metal, has strong reducing properties. In contact with water, it reacts violently, such as boiling water, hissing, releasing hydrogen gas, and generating sodium hydroxide.
4-hydroxybenzenesulfonate (dihydrate), in this compound, the sulfonic acid group -SO 🥰 Na is hydrophilic, which can make the substance easily soluble in water. Hydroxy-OH gives it a certain reactivity.
From the perspective of acid-base properties, sulfonic acid groups are highly acidic and can neutralize with bases. Hydroxy groups can also participate in reactions such as esterification under suitable conditions. This compound can ionize sodium ions and 4-hydroxybenzenesulfonate ions in aqueous solution.
In terms of redox properties, sodium can be used as a reducing agent and can react with many oxidants. In sodium 4-hydroxybenzenesulfonate (dihydrate), although there is no part that is easily oxidized, under the action of a specific strong oxidant, the hydroxyl group may be oxidized, or the benzene ring structure may change.
Furthermore, its stability also needs to be considered. At room temperature and pressure, if the environment is dry, sodium 4-hydroxybenzenesulfonate (dihydrate) is relatively stable. In case of extreme conditions such as high temperature, strong acid and alkali, decomposition or other chemical reactions may occur. The chemical properties of these two are complex and changeable, and they have important uses and research value in many chemical fields.

What are the physical properties of Sodium 4-hydroxybenzene Sulfoate (dihydrate)

Sodium 4-hydroxybenzene sulfonate (dihydrate) is a special compound. Its physical properties are interesting and worth exploring in detail.
In terms of its appearance, it is often white crystalline, like fine ice crystals, pure and uniform in texture, shining in natural light with a soft luster, delicate and beautiful.
In terms of solubility, it is easily soluble in water, just like snowflakes melting into a stream, quietly disappearing, but giving the water body a special chemical property. This property is due to the formation of hydrogen bonds and other interaction forces between its molecular structure and water molecules, allowing it to spread freely in the embrace of water to form a uniform solution.
Looking at its melting point, it is about a specific temperature range. When the external temperature rises to that point, the compound will gradually convert from the solid state to the liquid state, just like the melting of ice. This process requires a certain amount of heat to be absorbed, reflecting the strength of the intermolecular forces.
Again, its density is relatively moderate, neither light as a feather nor heavy as lead. This property is closely related to the way its molecules are deposited and the atomic weight. Under different environmental conditions, the density may vary slightly, but the amplitude is very small.
Its hygroscopicity is also significant. It can absorb water like a sponge in the air and maintain its dihydrate form. This property makes it necessary to pay attention to the influence of environmental humidity when storing and using it.
In conclusion, the physical properties of sodium 4-hydroxybenzene sulfonate (dihydrate) are unique and of great significance in many fields. In-depth understanding of it will help to use this compound more appropriately and maximize its effectiveness.

What is the production method of Sodium 4-hydroxybenzene Sulfoate (dihydrate)

To prepare sodium 4-hydroxybenzenesulfonate tetrahydrate, the method is as follows:
First take an appropriate amount of phenol and place it in the reactor. Add a certain amount of concentrated sulfuric acid, which is the key reagent for sulfonation. Heat up to a suitable temperature, usually between 100-150 ° C, to maintain this warm state, so that phenol and concentrated sulfuric acid can fully react. During this time, the sulfate radical will replace the hydrogen atom on the phenyl ring to form 4-hydroxybenzenesulfonate.
After this reaction is completed, cool the reaction product and cool down. Then, slowly add the sodium hydroxide solution. Pay attention to the rate and amount of addition to ensure a smooth reaction. Sodium hydroxide will neutralize with 4-hydroxybenzenesulfonate to form 4-hydroxybenzenesulfonate sodium.
After the neutralization reaction is completed, the reaction solution is evaporated and concentrated. The water is gradually evaporated by heating, and the concentration of the solution gradually increases. When a certain degree is reached, the crystallization is cooled, and the sodium 4-hydroxybenzene sulfonate will precipitate in the crystalline form.
Then, the crystals are separated from the mother liquor by filtration. The crystals are washed with an appropriate amount of cold water to remove attached impurities.
Finally, the washed crystals are placed in an oven, controlled at a suitable temperature, and dried to obtain the finished product of sodium 4-hydroxybenzene sulfonate tetrahydrate. The whole process requires precise control of factors such as temperature, reagent dosage and reaction time to produce high-purity products.

Sodium 4-hydroxybenzene Sulfoate (dihydrate) in storage and transportation

4-Hydroxybenzenesulfonate sodium dihydrate should pay attention to the following things during storage and transportation:
First, when storing, it should be placed in a cool, dry and well-ventilated place. This is because if the substance is in a humid and warm environment, or due to water vapor invasion and high temperature, its properties will change, which will affect its quality. If the humidity is too high, the dihydrate may deliquescent and destroy its original structure; if the temperature is too high, it may cause a chemical reaction and cause it to deteriorate.
Second, it needs to be stored separately from oxidants and acids, and must not be mixed. Due to its chemical properties, coexisting with oxidants, or triggering oxidation reactions; contact with acids, or leading to other chemical reactions, will cause 4-hydroxybenzene sulfonate sodium dihydrate to lose its original characteristics, and even dangerous.
Third, the storage area should be equipped with suitable containment materials. In case of leakage, it can be collected in time to avoid its spread and pollution of the environment, and at the same time, it can also prevent it from accidentally reacting with other substances.
Fourth, during transportation, be sure to ensure that the container is well sealed. The road is bumpy. If the container is poorly sealed, the substance or leakage will not only lose materials, but may also cause harm to the transportation environment and personnel.
Fifth, keep away from fire and heat sources during transportation. Under heat conditions, the chemical stability of this substance may be affected, and it is close to fire and heat sources, which greatly increases the possibility of dangerous reactions.
Sixth, transportation vehicles should be equipped with corresponding varieties and quantities of fire equipment and leakage emergency treatment equipment. In the event of an accident on the way, it can be responded to in time to reduce the degree of harm.
