What are the main uses of Sodium α-Olefinsulfonate?
Sodium-alpha-olefin sulfonate has a wide range of uses. In the field of daily chemical industry, it is often a key component of detergents. It has excellent decontamination ability and can efficiently remove oil stains and stains. With its unique molecular structure, it can reduce surface tension at the interface between water and oil, making grease easily dispersed and emulsified in water. Therefore, it often exists in various household cleaning agents, such as washing powder and detergent, which can make cleaning more convenient and decontamination more thorough.
In the field of industrial cleaning, it is also important. For example, cleaning after metal processing can remove oil stains on metal surfaces, cutting fluid residues, etc., to ensure that metal products are clean and do not damage their performance. And in the textile printing and dyeing industry, it is helpful for the fabric pretreatment process, removing impurities on the surface of the fabric, laying the foundation for subsequent dyeing, finishing and other processes, making the fabric dyeing more uniform and brighter.
Furthermore, in the petroleum industry, it can be used as an oil displacement agent. It can improve the wettability of the surface of the reservoir rock, reduce the interfacial tension between oil and water, promote the release of crude oil from the rock pores, and improve the oil recovery rate, which is of great significance in energy extraction. In the field of emulsion polymerization, sodium-α-olefin sulfonates can be used as emulsifiers to stabilize the emulsion system and ensure the smooth progress of the polymerization reaction, which is essential for the preparation of high-quality polymer emulsions.
How safe is Sodium α-Olefinsulfonate?
Sodium α-Olefinsulfonate is a common ingredient in daily chemical products. Its safety is related to the health of the user and is very important.
In terms of toxicity, many studies have shown that this substance has low acute toxicity. When ingested orally, at normal doses, it rarely causes serious toxicity to organisms. In terms of skin contact, it generally does not cause strong irritation. Numerous experiments have been conducted on animals and human volunteers to observe their reactions after exposure to this substance. Most of them show only mild discomfort and few serious allergic or irritating symptoms.
In terms of environmental safety, Sodium α-Olefinsulfonate has certain biodegradability. In the natural environment, it can be gradually decomposed by the action of microorganisms, so the risk of lasting pollution to the environment is low. And the decomposition products usually do not pose significant environmental hazards.
However, when using this product, it still needs to follow relevant norms and standards. Although its safety is high, excessive or improper use may also cause some problems. For some sensitive individuals, it may cause mild skin allergies, but such situations are relatively rare. And if not properly handled during production and use, it may also cause temporary effects on the local environment.
Overall, Sodium α-Olefinsulfonate is highly safe under normal use specifications, can be an active ingredient in daily chemical products, and is more friendly to users and the environment.
What is the proportion of Sodium α-Olefinsulfonate used in different products?
Sodium-alpha-olefin sulfonate is used in various products in different proportions. For cleansing products and the like, it often accounts for three to eight parts of the formula. Because of its good decontamination and foaming ability, it can effectively wash away facial oil and dirt, and it is mild and less irritating, suitable for most skin types.
As for laundry detergents, the ratio may be between five and fifteen parts. This is because sodium-alpha-olefin sulfonate has strong decontamination power, excellent removal effect on common stains, and can make clothes soft and fluffy after washing, so it is very important for laundry cleaning.
In the field of household cleaners, its use ratio is mostly eight to twenty parts. This ingredient can efficiently remove stubborn stains in kitchens, bathrooms, etc., and can quickly decompose oil, making the home environment refreshing and clean.
In personal care products, such as body wash and shampoo, it accounts for about two to six parts. Sodium-alpha-olefin sulfonate not only produces a rich foam, brings a comfortable use experience, but also is gentle to the skin and hair, and can maintain the water and oil balance between the skin and scalp.
In short, sodium-alpha-olefin sulfonate is used in different products, according to its functional needs and characteristics, and the use ratio is flexibly adjusted. It is all giving full play to its advantages of cleanliness and mildness to meet the diverse needs of the public.
What are the advantages of Sodium α-Olefinsulfonate compared to other surfactants?
Sodium-alpha-olefin sulfonate (Sodium-alpha-Olefinsulfonate) is unique among all surfactants.
First, it has good decontamination power. Its molecular structure is exquisite, one end is lipophilic and the other end is hydrophilic, which can efficiently absorb oil stains and make them disperse in water. Even in the face of heavy dirt stains, it can quickly disintegrate, and the cleaning power is quite good. Compared with other active agents, the decontamination efficiency is particularly excellent.
Second, the biodegradability is very good. In the natural environment, it can be decomposed by microorganisms faster and turned into harmless substances, without long-term residue. It contributes a lot to environmental protection, far more than some refractory active agents.
Third, the foam performance is suitable. It can produce rich and stable foam. During the washing process, the foam can help it better cover the surface of the product to be washed and enhance the cleaning effect, but it will not be difficult to rinse without too much foam. Compared with some active agents with too much or too little foam, this point has obvious advantages.
Fourth, it is gentle to the skin. When in contact with the skin, it is slightly irritating and can reduce damage to the skin. It is suitable for many cleaning products that are in close contact with the human body, such as hand sanitizer, body wash, etc., which is beyond the reach of many strong irritating active agents.
Fifth, good chemical stability. Under common temperature and pH conditions, it can maintain stability and does not easily decompose and deteriorate, ensuring the stability of the product during storage and use. It is more practical than those active agents with poor stability.
What is the production process of Sodium α-Olefinsulfonate?
The production process of sodium-alpha-olefin sulfonate is an important matter in chemical manufacturing. The first step is in the selection of raw materials, alpha-olefin and sulfonating agent are the key materials. Sulfur trioxide is often used as a sulfonating agent, because of its high reactivity, it can cause efficient sulfonation reactions.
At the beginning of production, it is necessary to make α-olefin and sulfur trioxide contact under specific conditions. Temperature, pressure and material ratio are all important factors. Temperature should be controlled within a certain range. If it is too high, the reaction will be excessive and by-products will be easily generated. If it is too low, the reaction will be slow and the efficiency will not be obvious. Pressure also needs to be adjusted to help the reaction proceed smoothly. The material ratio is also carefully considered to make the two fully react and achieve the best yield.
After the sulfonation reaction is completed, the product still contains impurities and needs to be processed later. Neutralization is often used to neutralize excess acid with lye to make the pH of the system appropriate. Then, separation and purification are performed to remove unreacted raw materials, by-products and other impurities to improve the purity of the product.
Repeat with refining steps, such as filtration, distillation, crystallization, etc., to make sodium-alpha-olefin sulfonate meet the required Quality Standards. Through these various processes, high-purity sodium-alpha-olefin sulfonate can be obtained to meet the needs of industrial, daily use and other fields. The process is fine and complex, and each step needs to be precisely controlled to obtain good products.
