What are the physical properties of Sodium 4-Hydroxybenzene Sulfoate (Anhydrous)
The physical properties of sodium and sodium 4-hydroxybenzenesulfonate (anhydrous) are particularly important, which is related to its use and characteristics.
Sodium 4-hydroxybenzenesulfonate (anhydrous), at room temperature, is in the state of white crystalline powder with fine texture. It has good water solubility and can be quickly dissolved in water, due to the hydrophilicity of the sulfonic acid groups in the molecular structure. And its aqueous solution is neutral or slightly alkaline, which is a key property in many chemical processes.
When it comes to melting point, its melting point is quite high, which indicates that the intermolecular forces are strong and the structure is stable. This stability allows sodium 4-hydroxybenzenesulfonate (anhydrous) to remain solid within a certain temperature range, not prone to phase changes, and to maintain its own structure and properties under high temperature environments, which is of great significance in industrial production and storage.
Furthermore, sodium 4-hydroxybenzenesulfonate (anhydrous) has weak hygroscopicity. This characteristic makes it difficult to absorb moisture in the air and deliquescence in general humidity environments, and can be kept dry for a long time, which is convenient for storage and transportation, and reduces the worry of quality changes due to moisture.
Sodium is an active metal. Its texture is soft and can be easily cut with a knife. The section is silver-white and has a metallic luster. The density of sodium is less than that of water and greater than that of kerosene, so it can be stored in kerosene. Sodium has a low melting point and melts into bright globules when heated. And its chemical properties are extremely active, reacting violently in contact with water, generating sodium hydroxide and hydrogen, and releasing a large amount of heat at the same time.
When sodium comes into contact with sodium 4-hydroxybenzenesulfonate (anhydrous), if conditions are suitable, the activity of sodium may initiate a chemical reaction, changing the original physical properties and chemical structure of sodium 4-hydroxybenzenesulfonate (anhydrous). The specific reaction situation depends on the environmental conditions and the ratio of the two.
What are the chemical properties of Sodium 4-Hydroxybenzene Sulfoate (Anhydrous)
The chemical properties of sodium and sodium 4-hydroxybenzenesulfonate (anhydrous) are quite specific. Sodium is a reactive metal with strong reducing properties. Its texture is soft and silver-white, and it reacts rapidly when exposed to water at room temperature to generate sodium hydroxide and hydrogen gas, and this reaction is violent, often accompanied by a large amount of heat release, causing hydrogen combustion.
As for sodium 4-hydroxybenzenesulfonate (anhydrous), this is an organic sulfonate. In its structure, the hydroxyl group is connected to the benzene ring, giving the molecule a certain hydrophilicity and reactivity. The conjugate system of the benzene ring makes the molecule relatively stable. The sodium sulfonate group has good water solubility and ionic properties.
When sodium meets sodium 4-hydroxybenzenesulfonate (anhydrous), sodium may be substituted with active hydrogen on the benzene ring, which is due to the strong reactivity of sodium. However, the specific reaction process depends on the reaction conditions, such as temperature and reaction medium. Under high temperatures, the reaction may become more intense; in specific organic solvents, the reaction path may be different from the product.
4-hydroxybenzenesulfonate (anhydrous) can ionize sulfonate ions and sodium ions in water. The aqueous solution is alkaline and originates from the hydrolysis of sulfonate ions. The addition of sodium to this compound system may break the original ionization equilibrium, triggering a series of complex chemical changes, which affect the formation of products and the direction of reaction. The chemical properties of the two are complex and changeable. When they interact, the reaction phenomena and products vary according to conditions, which is a topic worthy of further investigation in chemical research.
What is the production method of Sodium 4-Hydroxybenzene Sulfoate (Anhydrous)?
The method of preparing anhydrous sodium 4-hydroxybenzene sulfonate has been known since ancient times. The method is probably to take an appropriate amount of phenol first, which is the root material. Put phenol in a reactor, use sulfuric acid as a sulfonating agent, add it slowly, and control its temperature and reaction time. Sulfuric acid meets phenol, and then it changes into sulfonation. A sulfonic acid group is added to the phenol ring of phenol to produce 4-hydroxybenzene sulfonate.
At this time, the obtained product is not anhydrous sodium 4-hydroxybenzene sulfonate. To obtain sodium salt, it needs to be neutralized with sodium hydroxide. Slowly add sodium hydroxide solution until the pH of the reaction solution is enough. This step needs to be done with caution to observe the subtle changes in the reaction to prevent it from being too much. After neutralization, a solution of sodium 4-hydroxybenzenesulfonate is obtained.
To remove its water and obtain an anhydrous state, the method of evaporation and concentration is commonly used. At a moderate temperature, the water in the solution gradually disperses, and the concentration of sodium 4-hydroxybenzenesulfonate gradually increases. When there is a crystallization appearance, move to a cooling place to allow the crystal to slowly precipitate. The precipitated crystal, or contains some impurities, can be purified by recrystallization. Dissolve it in an appropriate solvent, then evaporate and cool, to obtain a relatively pure anhydrous sodium 4-hydroxybenzenesulfonate crystal. During the whole process, the temperature, pH, and the ratio of materials need to be carefully controlled to obtain high-quality anhydrous sodium 4-hydroxybenzenesulfonate.
What are the precautions for Sodium 4-Hydroxybenzene Sulfoate (Anhydrous) in storage and transportation?
4 - Sodium hydroxybenzenesulfonate (anhydrous), during storage and transportation, it is necessary to pay attention to many matters.
The first thing to pay attention to is the storage environment. This substance should be stored in a dry and well-ventilated place, because moisture can easily cause deliquescence and deterioration, which will damage the quality. In the warehouse, the humidity should be strictly controlled and not too high.
Next, pay attention to the temperature. Avoid high temperatures, which may cause changes in its chemical properties or even trigger safety risks. Store in a cool place to prevent temperature from exceeding the limit.
Furthermore, store it at a distance from other chemicals, especially oxidizing and reducing substances, to avoid mutual reaction and cause danger. At the same time, the container must be well sealed to prevent it from coming into contact with outside air, water vapor, etc.
When transporting, the packaging must be firm and reliable. Make sure that the packaging is not damaged and leaked during handling, loading and unloading. Transportation vehicles should also be maintained in dry and cool conditions, avoiding exposure to the sun and rain on the way. Transport personnel should also be familiar with the characteristics of this material. In case of accidental leakage, etc., they can be disposed of quickly according to the correct method to prevent the harm from expanding. And the transportation process must strictly abide by relevant regulations and standards to ensure safety.
